description: Abstract

This study aims to develop an internal optimization model for the allocation of teaching budgets to local regular undergraduate universities, focusing on identifying internal indicators that influence budget allocation and their interrelationships. Utilizing a mixed-methods approach, the research surveyed 511 participants from 16 public undergraduate universities in Sichuan Province, incorporating both quantitative and qualitative analyses through SPSS and interviews. The findings revealed five key internal indicators: the Scale of the Faculties (SF), Special Projects (SP), Discipline and Professional Construction (DPC), Collaborative Education (CE), and Teaching Reform and Research (TRR), all positively associated with teaching budget allocation. Notably, SF was found to mediate the relationship between the other variables and budget allocation. The constructed optimization model demonstrated robustness through various fit indices, indicating a substantively meaningful and parsimonious model. The study holds significant policy implications, offering a strategic guide for budget allocation that could enhance educational outcomes, transparency, and accountability in fund management. Academically, it provides a theoretical framework for educational economics, potentially impacting related fields such as public administration and organizational theory. Practically, it offers valuable insights for university administrators, facilitating informed decision-making to maximize educational quality and performance. This research contributes to the broader discourse on financial management within educational institutions, providing a benchmarking tool for optimal resource allocation and encouraging the adoption of best practices in financial decision-making.
STRUCTURAL CHARACTERISATION OF HIGHLY BRANCHED ISOPRENOID ALKENES FROM SEDIMENTS AND ALGAE
Creators: name: COOKE, DAVID ALAN
Publisher: name: University of Plymouth
Year: 1995

description: At least fourteen C25 highly branched isoprenoid (HBI) alkenes have been previously reported in estuarine and coastal sediments from locations worldwide. The parent alkane structure has been proven but only a few of the double bond positions established previously. A wide body of evidence suggests that the compounds have a diatomaceous origin, with one report in the laboratory cultured diatom Haslea ostrearia. Alkenes with more than two double bonds appear to be rapidly removed from the hydrocarbon fraction of most sediments. There is evidence that some of the alkenes react rapidly with sulphur to form S-containing analogues. HBIs, both as hydrocarbons and S-containing analogues, may prove useful environmental indicators once the sources and exact structures have been established. A study of the temporal variations of HBI and carotenoid biomarker concentrations in Tamar sediments was conducted during 1994. The concentrations of C25 HBI alkenes exhibited strong negative correlations with those of /J-C2i:6 and fucoxanthin, common diatom markers. The strong inverse variance suggests that HBI concentrations are related to diatom populations in the Tamar estuary. Six C25 HBI alkenes ranging from a diene to hexaene have been isolated from ‘bulk' cultures of Haslea ostrearia and Caspian Sea sediments. The occurrence of HBIs in Haslea ostrearia is thus confirmed. Furthermore, the structures were unambiguously assigned by detailed nuclear magnetic resonance spectroscopy and mass spectral analysis, as well as by chemical degradation. The hydrocarbons are 2,6,10,14-tetramethyl-7-(3- methylpent-4-enyl)pentadec-5-ene; 2,10,l4-trimethyi-6-methylene-7-(3-methyIpent-4- enyl)pentadec-9-ene; 2,10,14-trimelhyl-6-methylene-7-(3-methylpent-4-enyl)pentadec- 9,13-ene; 2,10,14-trimethyl-6-methylene-7-(3-methylpent-4-enyl)pentadec-2,9,13-ene; 2,6,10,14-tetramethyl-7-(3-methyIpent-4-enyl)pentadec-2,5,9,13-ene and 2,6,10,14- tetramethyl-7-(3-methylenepent-4-enyl)pentadec-2,5,9,l3-ene. Structural elucidation of the HBI alkenes produced by Haslea ostrearia and comparison with sedimentary distributions suggests that the latter may arise from a facile double bond isomerisation of the biosynthetic compounds. The evidence presented suggests that inputs from Haslea ostrearia may account for at least eight of the dominant sedimentary HBI alkenes. The unusual behaviour exhibited by HBI alkenes during solid phase chromatography suggests that an incomplete record exists for HBI alkenes reported in the environment.

THE FABRICATION AND STUDY OF METAL CHELATING STATIONARY PHASES FOR THE HIGH PERFORMANCE SEPARATION OF METAL IONS
Creators: name: Shaw, Matthew James
Publisher: name: University of Plymouth
Year: 2000

description: The preparation and characterisation of chelating sorbents suitable for the high efficiency separation of trace metals in complex samples, using a single column and isocratic elution, is described. Hydrophobic, neutral polystyrene divinylbenzene resins were either impregnated with chelating dyes or dynamically modified with heterocyclic organic acids, using physical adsorption and chemisorption processes respectively. A hydrophilic silica substrate was covalently bonded with a chelating aminomethylphosphonic acid group, to assess the chelating potential of this molecule. These substrates were characterised in terms of metal retention capability (selectivity coefficients and capacity factors), separation performance, column efficiency and suitability for analytical applications. Chelating molecules with different ligand groups were found to have unique selectivity patterns dependant upon the conditional stability constants of the chelate. Other factors, including mobile phase constituents - complexing agents, ionic strength and pH, column length and column capacity were additionally investigated to examine their effect upon the separation profiles achieved. The promising metal separation abilities illustrated by a number of these chelating columns were exploited for the determination of trace toxic metals in complex sample matrices using High Performance Chelation Ion Chromatography (HPCIC). This included the determination of beryllium in a certified stream sediment, uranium in seawater and a certified stream sediment, and cadmium, lead and copper in a certified rice flour. The results for each analysis fell within the certified limits, and reproducibility was good. The optimisation of post column detection systems using chromogenic ligands additionally gave good detection limits for the metals in each separation system.

description: Building and sustaining relationships with university faculty and students can be challenging for liaison librarians. Using a concept mapping approach to organizing librarian liaison activities provides a frame of reference for planning outreach. Activities were grouped by four main elements of proactive customer service: visibility, relevance, usefulness, and timeliness. Liaison effectiveness can be enhanced by choosing complementary activities from each of the four elements. The best options for engagement will vary depending upon the type of customer, setting, and disciplines. The concept map is useful for envisioning how research and instruction activities interrelate and contribute to academic community engagement.
Teleseismic P-Wave Tomogram of the Yellowstone Plume

description: Inversion of a new data set of teleseismic P-wave traveltimes from three PASSCAL seismic deployments around the Yellowstone hotspot reveals a 100 km diameter upper mantle plume that extends from the Yellowstone volcanic caldera to 500 km depth and dips 20° to the northwest. A monotonic decrease in the velocity perturbation of the plume from -3.2% at 100 km to -0.9% at 450 km is consistent with a uniform thermal anomaly of 180°C. Where the plume crosses the 410 km discontinuity, previous research shows a depression in the 410 km discontinuity consistent with a warm plume (Fee and Dueker, 2004). Additionally, a region of high velocities extends to 250 km beneath the Wind River basin in NW Wyoming that may represent a convective downwelling of the lithosphere.

SUB-SURFACE MIGRATION OF AN OIL POLLUTANT INTO AQUIFERS
Creators: name: MACDONALD, LOUISE ANN
Publisher: name: University of Plymouth
Year: 2000

description: The risk to groundwater quality following a sub-surface spillage of immiscible pollutants such as oil, petroleum and other organic chemicals is an increasingly potent threat, through escalating industrial application of such pollutants. This study significantly enhances the understanding of the flow of immiscible pollutants within soil, through field scale investigations to define the spatial variability and extent of a contaminated area and the development of a comprehensive framework for the analysis of oil pollutant migration. This study represents a first attempt by researchers to analyse oil pollutant migration on a wide range of scales, from pore- to field-level. The research shows that quantity of pollutant is a critical factor in determining the extent of oil migration. Permeability and porosity of the sample material are also important secondary factors. High permeability assists the migration of oil pollutants. Soils with a high porosity allow the pollutant to migrate vertically under the influence of gravity, whereas soils with low porosity induce lateral oil migration, as the oil spreads from the point of injection. A Jull scale field study using contrasting soil types determines that oil migration is approximately symmetrical about the point of injection. Experimental data is used to establish modelling capabilities for the characterisation of pollutant migration. Modelling is undertaken at two levels. The first consists of the development of simple Gaussian equations based upon observations of oil glomuses. The glomus approach, newly developed in this work, can be compared to a fractal model, with the glomuses observed in each of the different scales studied.

description: We used an allometric approach to compare the minimum nitrogen requirements (MNR) and the total endogenous nitrogen loss (TENL) of nectar- and fruit-eating birds with those of omnivorous birds. These two parameters were 4x higher in omnivores than in nectarivores and frugivores. In nectarivorous-frugivorous birds, MNR was 152.8 mg N kg-0.76 day-1; in omnivorous birds, it was 575.4 mg N kg-0.76 day-1. Similarly, TENL was 54.1 mg N kg-0.69 day-1 in nectarivores-frugivores, and 215.3 mg N kg-0.69 day-1 in omnivores. The residuals of the allometric relationships between TENL and MNR and body mass were positively correlated, which suggests that a large proportion of the interspecific variation in MNR is explained by variation in TENL. Although our results show that nectar- and fruit-eating birds have low nitrogen requirements, the mechanisms that these animals use to conserve nitrogen remain unclear.
DEVELOPMENT OF A LOW PRESSURE-INDUCTIVELY COUPLED PLASMA-ION SOURCE FOR MASS SPECTROMETRY
Creators: name: O'Connor, Gavin Thomas
Publisher: name: University of Plymouth
Year: 1998

description: A low pressure-inductively coupled plasma (LP-ICP) ion source has been investigated for the production of atomic and molecular ions for mass spectrometry (MS). A dedicated LPICP- MS was constructed, by modifying a Hewlett Packard mass selective detector, to detect ions from the LP-ICP. The ion sampling interface and ion optics were designed using established theory and the use of a computer simulation program. Perfluorotributylamine was continuously introduced into the LP-ICP, via a molecular leak, and the ion sampling interface, plasma forward power, and plasma gas flow rates, were optimised. When the LP-ICP ion source was sustained at 6W with a gas flow of 6 ml min'* helium, and iodobenzene and dibromobenzene, introduced via GC, only atomic signals for iodine and bromine were observed. Detection limits were 4 and 76 pg for iodobenzene and dibromobenzene respectively. The addition of nitrogen to a LP helium ICP increased the molecular signal for chlorobenzene, resulting in a detection limit of 2 pg. However, the addition of nitrogen did not aid the production of molecular ions of iodobenzene and dibromobenzene. When 0.07 ml min' of isobuiane was added to the LP-ICP mass spectra similar to those obtained by an electron impact source were observed. However, on the addition of more isobutane only the molecular ions (M*) for chlorobenzene, iodobenzene and dibromobenzene were observed. The detection limits for the instrument operating in the molecular mode were 100, 140 and 229 pg for chlorobenzene, iodobenzene and dibromobenzene respectively. Langmuir probe measurements were used to asses the effect of plasma forward power and gas flow rate on the local plasma potential, ion number density, electron temperature and electron number density within the LP-ICP. The local plasma potential varied from +50 V to -20 V depending on the plasma conditions used. The ion and electron number densities increased with increasing plasma power, with ion number densities of approximately 10^ cm' ^ and electron number densities of approximately at 10* cm ^ The effect of extra plasma gas had a less distinct affect on the plasma excited species. A plasma sustained at 6 W, 7 ml min'' helium and 1.8 ml min'* isobutane was used to provide both quantitative and qualitative information of tetraethyllead in the standard reference friel (NBS SRM 1637 II), with .the determined value of 13.06 ± 0.91 being in good agreement with the certified value of 12.9 ± 0.07 expressed as total lead.

Subjects: subject: Aerosol, shipping, metals, sulfur, legislation, V/Ni
subject: ResM

description: Maritime shipping is a significant source of anthropogenic emissions, with annual growth of shipping continually on the rise. In the marine environment, shipping emissions often dominate the atmospheric deposition of sulfur and contribute significantly to global sulfur emissions. As a result, the International Maritime Organisation (IMO) introduced a regulation on 01/01/2020 restricting global marine fuel sulfur content from 3.5% to 0.5% w/w. The present study investigated the changes in airmass marine aerosol chemical character arriving at the Penlee Point Atmospheric Observatory (PPAO; 50∘19′ N, 4∘11′ W) to gain insight into the efficacy of the IMO-2020 regulation. The observatory in Southwest England is ideally located next to the port of Plymouth and near to a major international shipping lane in the English Channel with high density marine traffic. Aerosol filter samples were collected from 2020-2021 (n=64). Filter samples were water-leached and subsequent leachates were analysed for major ions using Ion Chromatography, and trace elements using Inductively Coupled Plasma – Mass Spectrometry. Concentrations of V/Ni and calculated non-sea-salt sulfate (nss-SO42-) were compared to PPAO datasets from 2015-16 and 2017-18 respectively. The vanadium/nickel (V/Ni) ratio has been widely used as a marker of shipping emissions in the marine boundary layer, with the range of 2.5 to 4 indicating shipping activity. Trace element analysis showed a drop in V from 2.91 pmol/m3 to 1.44 pmol/m3, and Ni increase from 0.95 pmol/m3 to 4.8 pmol/m3. V/Ni ratio post-IMO-2020 decreased from 3.3 to 0.28, showing a significant change to the trace metal signature of marine aerosols. Post-IMO-2020 nss-SO42- concentrations were significantly lower than pre-IMO-2020 values (n=109, p<0.05), with total nss-SO42- concentration dropping from 1.35 µg/m3 to 0.33 µg/m3. A change from nss-SO42- dominated atmospheric sulfur pre-IMO-2020 to primarily natural dimethylsulfide dominated sulfur was observed. Clear seasonal nss-SO42- fluctuations increasing during spring and summer were visible post-IMO-2020. These results indicate a major change to the atmospheric chemistry of sulfur in the lower atmosphere near to regions of intense shipping.
THE EFFECT OF SYNOPTIC SCALE WEATHER AND TOPOGRAPHY ON ROAD SURFACE TEMPERATURES IN DEVON
Creators: name: MCLEAN, PETER JAMES
Publisher: name: University of Plymouth
Year: 1995

description: Microclimates of various road weather stations in Devon were examined. Road surface temperatures were measured during various synoptic conditions. Data from the thermal mapping exercise conducted by Vaisala TMI were analysed and categorised as clear and calm, cloudy and windy, and a condition between the two extremes. Results indicate valleys to be relative cold spots in clear conditions, and high altitude stations are cold spots during cloudy conditions. A separate case study during the cold spell of February 1991 reinforced the conclusion and extended these views county wide. Coastal stations with surface winds were observed to be 1 to 3 deg.C warmer than inland stations. Reaction times, the delay in road temperature reaction due to synoptic change, showed for the most difficult forecasting scenario on the passage of a cold front, small reaction times (less than 30 minutes) at exposed sites when clear skies resulted, sheltered sites having a reaction time of up to 2 hours. Sheltered sites in valleys had the largest temperature drop due to cold air drainage. A surface climate model was used in retrospect to predict road surface temperatures at night, each station having its own characteristic exposure. Cloud change was estimated from satellite images. Results indicate predicted minimum temperature within 0.5 deg.C of observation. Real time forecasts were tried and an accuracy of 65% at this level was achieved. These results were equal or better than the existing "Open Road" forecasts.

description: In this paper, we investigate the influence of high temperature and high pressure hot pressure on the magnetic and transport properties of polycrystalline CrO2 samples compacted under high pressure and high temperature of up to 5 GPa and 600 °C, respectively. The magnetic moment increases with compacting temperature, and a metal-semiconductor transition is observed in hot-pressed samples, different from the cold-pressed samples. These results indicate that the formation of Cr2O3 at the grain boundaries of CrO2 is suppressed by hot pressure. The magnitude of low field magnetoresistance of up to 1 T at 5 K is enhanced first with the increase of compacting temperature and then decreased under higher compacting temperature. This result can be well explained by the change of spin-dependent tunneling at the modulated grain boundaries of CrO2 due to the transformation from Cr2O3 to CrO2 under hot pressure.
Otolith morphology and population dynamics of grenadier bycatch to improve fishery observer species identification and fisheries management at the Heard and McDonald Islands
Creators: name: Connor, William
Publisher: name: University of Tasmania
Year: 2024

description: Species identification accuracy is crucial within fisheries management as species contain different fishery sensitivities. Observer’s onboard fishery vessels identify target and bycatch species while recording haul depth, time, and catch length and weight data. However, the acknowledged yet understudied issue of species identification is reliant upon fisheries observers and their training. Variable observer experience and challenging working environments stimulate species misidentification, potentially presenting data bias. When commercial fisheries catch morphologically similar species, observer misidentification can lead to incorrect species within historical catch records and species population management.
The Patagonian toothfish bottom longline fishery of the Heard and McDonald Islands (HIMI) has four Macrourus grenadier species known as bycatch. Morphological and distributional differences have split the four grenadier’s bycatch limits from a pooled genus group into pairs ‘Macrourus caml and M. whitsoni’ and ‘M. holotrachys and M. carinatus’ respectively, however, similar characteristics between paired species contribute to fishery observer misidentification. Understanding how to improve observer accuracy is important for accurate Macrourus stock information at HIMI.
This thesis provides a literature review supporting the research manuscript examining baseline descriptions of Macrourus species biological data and otolith shape morphology, to improve fishery observer identification accuracy. We studied a total of 800 otoliths covering all four Macrourus species collected from HIMI's longline fishery (2015–2021). Otolith shape features were analysed to discern the four species, while random forest models were conducted utilising otolith morphometrics to assess accuracy between species pairs and identify important otolith shapes differentiating species. Age structures were constructed to potentially indicate longline, depth and location impacts. Our research presents baseline knowledge valuable for current and future observers, provides a novel tool that highlights species identification accuracy to determine training for individual observers, and forms the basis of regional impact on HIMI Macrourus species stock.
This thesis provides two chapters. Chapter one presents an extensive background literature review to the study field, rationale for research manuscript, research scope and limitations. Chapter two presents a manuscript prepared for submission to the Journal ‘Fisheries Research’ and has been formatted following the journal’s guidelines. Therefore, the manuscript and chapter one literature review contain content overlap. References are provided separately for chapter one and chapter two following identical formats of ‘Fisheries Research’ journal.

OXIDATION OF ZINC SULPHIDE
Creators: name: BASAK, BODHISATTWA
Publisher: name: University of Plymouth
Year: 1973

description: A physicochemical study has been made of roasting and sintering processes for zinc sulphide ores. The sulphides are oxidised to metal oxides or sulphates according to conditions, e.g. temperature and time of heating, composition of surrounding gases, whether under static or dynamic conditions. The mechanisms and kinetics of oxidation depend also on surface area, crystallite and aggregate sizes of the materials and the presence of any impurities. Thus, for basic oxidation studies, finely-divided zinc sulphide samples have been precipitated from solution at various pH levels and in the presence of different concentrations of eletrolytes. These experimental conditions have been correlated with changes in phase composition, surface area and crystallite and aggregate sizes during the formation of the precipitates and their subsequent ageing in solution at various temperatures. The oxidation of the two pure zinc sulphides and five ore Concentrates were investigated using the techniques of thermal analysis, gas sorption, X-ray diffraction, optical and electron microscopy. B)y use of D.T.A., the effects of temperature, time, grain size, flow rate and oxygen content of the air on the roasting of the above materials were determined. Changes in specific surface und average crystallite size (deduced from gas sorption) illustrate the influence of the zinc Sulphate on the sintering of the zinc oxide. Further experiments show the effect of small amounts of lead and iron sulphides on the zinc oxide sintering. Results have been correlated with oxidation rates. Attempts have been made to apply the basic researches to problems arising with the industrial roasting and sintering of natural ores such as spontaneous ignition (during shipment, storage and processing) and their poor sintering behaviour and incomplete sulphur removal at higher temperature. Improvements obtained by the use of lime and silica additives in the production of sinters have been investigated.

description: Powders of polymer and -Fe2O3 nanoparticles were pressed into pellets. The samples were annealed at 250 °C in pure hydrogen flow. X-ray diffraction spectra indicate that there is a complete phase transformation from -Fe2O3 to Fe3O4. Giant negative magnetoresistance MR was observed at room temperature and the MR ratio is over 14% in an applied field of 5.5 T. The maximum MR ratio is higher than 22% at 130 K. The drastic enhancement of the MR ratio is attributed to the fact that the polymer is an excellent barrier material and, more importantly, prevents the oxidation of the surface of Fe3O4. Our results clearly suggest that there is a high degree of spin polarization at room temperature for half-metallic Fe3O4.
PRIVATISATION, RURAL RAILWAYS AND COMMUNITY DEVELOPMENT
Creators: name: LOWNDES, THERESA MARIA
Publisher: name: University of Plymouth
Year: 1997

description: This thesis examines two separate, but interrelated, issues, namely rail privatisation and rural dependency on the availability of rail transport. The thesis was based on the proposition that rural accessibility permits the development and sustainability of the social and economic lives of a community and that this interrelationship is currently threatened by rail privatisation and the associated risks of line closures or service cutbacks. To test this proposition a thorough investigation into the theory and practice of privatisation was completed, together with a comprehensive survey of the travel arrangements of people living in rural communities served by branch line railways. A variety of research methods were employed, including desk-top studies involving literature searches, qualitative investigations to assist questionnaire design and the use of self-administered questionnaires by sample populations. The empirical results are presented and discussed against the background of introductory chapters which review the policy of privatisation, the evolution of rail privatisation and the role of the rural branch line. The concluding chapters present three different scenarios for the future of rural branch lines, ranging from closure to revitalisation, and outline areas where future research may be carried out. The main findings were that a substantial number of people depend on the branch lines to enable them to carry out a wide variety of journeys and it was concluded that branch line railways do indeed play a vital role in the development and sustainability of the rural community. Furthermore, it was concluded that rail privatisation may indeed pose a threat to the future provision of branch line services and as such could have far-reaching impacts on the future well-being of the rural community.
CHEMICAL AND PHYSICAL ANALYSIS OF LAMINATED SEDIMENT FORMED IN LOE POOL, CORNWALL
Creators: name: Pickering, David Alan
Publisher: name: University of Plymouth
Year: 1987

description: Laminated and annually-laminated sediments are found in Loe Pool. The origins of such laminations are investigated and evidence for their conditions of formation are presented. In all sediment analysed the combustion residue was greater than 80%, and in the black and grey annually-laminated sediment the organic matter was less than 3%. This indicated that the sediment was dominated by a minerogenic input. The high lacustrine sediment concentrations of copper, zinc and other heavy metals together with evidence from analysis of magnetic variables which indicated high levels of haematite, confirmed that a major sediment source was effluent from mine waste. Analysis of individual black and grey annual laminations revealed increased concentrations of chlorophyll c, phaeopigments and perylene together with a lower C:N ratio i n the black lamination. This indicated formation of the black layer in the summer months. From the high iron:manganese ratio and the low concentrations of calcium and carbonate i n the black lamination as compared with the grey layer it was apparent that the black lamination was formed under conditions of oxygen shortage, and the grey lamination was formed when the bottom waters were fully oxygenated. It was concluded that from the analysis of selected physical and chemical properties of individual laminations it was possible to identify the principal sediment source, the likely season of deposition of each lamination and the palaeo-redox condition of the lake at that time. From this information a hypothesis of the formation of the laminated sediments in Loe Pool is proposed. It is suggested that a dominant factor controlling sediment composition was the redox conditions at the time of deposition. These conditions were primarily influenced by lake depth, lake mixing, input of allochthonous material and the oxygen demand of sedimenting material.

description: Support for the Colorado high topography is resolved using seismic data from the Colorado Rocky Mountain (CRM) Experiment and Seismic Transects. The average crustal thickness, derived from P wave receiver function imaging, is 48 km. However, a negative correlation between Moho depth and elevation is observed, which negates Airy-Heiskanen isostasy. Shallow Moho (depth) is found beneath some of the highest elevations, and therefore, the CRM are rootless. Deep Moho (45-51 km) regions indicate structure inherited from the Proterozoic assembly of the continent. Shear wave velocities from surface wave tomography are mapped to density employing empirical velocity-to-density relations in the crust and mantle temperature modeling. Predicted elastic plate flexure and gravity fields derived from the density model agree with observed long-wavelength topography and Bouguer gravity. Therefore, low-density crust and mantle are sufficient to support much of the CRM topography. Centers of Oligocene volcanism, e.g., the San Juan Mountains, display reduced crustal thicknesses and lowest average crustal velocities, suggesting that magmatic modification strongly influenced modern lithospheric structure and topography. Mantle velocities span 4.02-4.64 km/s at 73-123 km depth, and peak lateral temperature variations of 600°C are inferred. S wave receiver function imaging suggests that the lithosphere-asthenosphere boundary is 100-150 km deep beneath the Colorado Plateau, and 150-200 km deep beneath the High Plains. A region of negative arrivals beneath the CRM above 100 km depth correlates with low mantle velocities and is interpreted as thermally modified/metasomatized lithosphere resulting from Cenozoic volcanism.
