Four-Dimensional Dynamic Synchrotron Microcomputed Tomography Imaging of Gas-Water Interface at High Pressure and Low Temperature
Authors: Alshibli Khalid , Jarrar Zaher A. 
Published: July 2020

Abstract
It is challenging to separate water from gas phases in computed tomography images of three-phase granular materials because water and most gases have close attenuation coefficients for x-ray. This article presents two techniques for three-dimensional (3D) imaging using synchrotron microcomputed tomography (SMT). Monochromatic x-ray beam that can be tuned for a specific energy level was used for a dual energy SMT that takes advantage of a sudden change in attenuation at the absorption edge of iodine. A solution of 4 % by weight potassium iodide (KI) and distilled water was used as a doping agent to saturate a column of sand as a test sample. The article focuses on how the technique was employed to image a column of sand as the degree of saturation changes. Water and air were separated easily, and the degree of saturation was calculated for the sand column at different drainage conditions. The article also presents a description of a high-pressure, low-temperature flow cell suitable for SMT imaging for dynamic monitoring of gas hydrate formation and dissociation. High photon flux beam (pink beam) enabled fast 4D imaging (3D plus time) of xenon gas hydrate formation. Hydrate specific area increased initially with increasing hydrate saturation and began to decrease after a threshold, which is evidence of Ostwald Ripening. For hydrate saturation less than 10 %, the predominant pore-habit was surface coating. Cementing pore-habit was observed at 15 % hydrate saturation, and pore-filling hydrate pore-habit was observed with further increase in hydrate saturation.

Published: July 2020

Abstract
Pneumatic pressure equipment is an important component of wind tunnel test systems, which have been extensively applied in most modern industries. To guarantee the reliability and safety of pneumatic pressure equipment, a regular inspection is needed. To improve the inspections process, automating the process of identifying defects continues to receive attention in the research community. In this paper, in order to achieve automatic defect identification, an improved feature extraction algorithm in eddy current pulsed thermography is presented. The presented feature extraction algorithm contains four elements: data block selection, variable step search, relation value classification, and between-class distance decision function. The data block selection and variable step search are integrated to decrease the redundant computations in the automatic defect identification. The goal of the classification and between-class distance calculation is to select the typical features of a thermographic sequence. The main image information can be extracted by the method precisely and efficiently. Experimental results are provided to demonstrate the capabilities and benefits (i.e., increased precision, reduced processing time) of the proposed algorithm in automatic defect identification.
Analytical and Experimental Investigation of Elastic–Plastic Strain Distributions at 2-D Notches
Authors: Ball D. L. , Martinez M. , Baldassarre A. , Dubowski D. M. , Carlson S. S. 
Published: July 2020

Abstract
Both elastic and elastic–plastic stress–strain response were studied for a series of part-circular and V-shaped notches in flat specimens. Both the peak strain at the notch root and the strain distribution along the notch bisector were studied. These quantities were determined analytically using detailed finite element analysis (FEA), and it was shown that significant differences can arise between detailed FEA results and two of the commonly used approximations for the peak notch strain response: Neuber’s rule and Glinka’s equivalent strain energy density theorem. These differences can become significant for notches with low acuity. The strain response for these configurations was also studied experimentally using two measurement techniques: optical fibers and surface differential displacement mapping. Agreement was shown between computed response strains and measured strains for some of the eight notch configurations and two aerospace alloys studied, while for others, experimental difficulties prevented agreement. These difficulties are described in detail.
Distribution of Felsic-Mafic Intrusive and Extrusive Rocks in the Earth’s Crust: Correlation with Magma Viscosity Regularities
Authors: Persikov E.S. 
Published: July 2020

Abstract
—New regularities of the viscosity of near-liquid felsic, medium, and mafic hydrous magmas have been established in a wide range of thermodynamic parameters and the Earth’s crust depths (1–30 km). The study was carried out using our new structural and chemical model of reliable predictions and by calculation of the viscosity of magmas of almost any composition. It is shown that these regularities are actually a quantitative physicochemical basis explaining the cause of the relative distribution of intrusive and effusive felsic and mafic rocks in the Earth’s crust. This confirms V.S. Sobolev’s idea of the relationship between the relative distribution of intrusive and effusive felsic, medium, and mafic rocks in the Earth’s crust and the laws of changes in the viscosity of hydrous magmas in a variable P–T field.
Large-Scale Fluid Transfer between Mantle and Crust during Supercontinent Amalgamation and Disruption
Authors: Touret J.L.R. , Huizenga J.M. 
Published: July 2020

Abstract
—Supercontinents are a unique feature of the planet Earth. A brief review of supercontinents formed since the Archean shows that before the Eocambrian, supercontinents, notably Gondwana and Rodinia, amalgamated through high-temperature mobile belts, all of them containing ultrahigh-temperature granulite occurrences. During the final stage of the amalgamation, the lower continental crust was brought to magmatic temperature (from ~900 to more than 1000 °C) during a variable time span, from less than 10 Ma in the recent shortlived orogens to more than 150 Ma in the Eocambrian (Gondwana) or Neoproterozoic (Rodinia) long-lived orogens. Ultrahigh-temperature granulites worldwide contain the same types of fluid inclusions, namely, dense CO2 and highly saline aqueous brines. The fluid amount in the peak metamorphic conditions is indicated by the amount of preserved fluid inclusions (especially CO2) and by the secondary effects caused by the fluids when they left the lower crust, including regional feldspathization, albitization or scapolitization, and formation of megashear zones, either oxidized (quartz–carbonate) or reduced (graphite veins). While some fluids may be locally derived either from mineral reactions or from inherited sediment waters, carbon isotope signature and petrographical arguments suggest that most fluids, both CO2 and high-salinity brines, are derived from carbonatite melts resulting from partial melting of metasomatized mantle. Ultrahigh-temperature metamorphism is critical for supercontinent amalgamation, but the associated fluid causes instability and disruption shortly after amalgamation.
Four Stages of the Thermal Evolution of Eclogites from the Maksyutov Complex (South Urals)
Authors: Fedkin V.V. 
Published: July 2020

Abstract
—Based on a detailed electron probe microanalysis of the composition and zoning of coexisting minerals (garnet, clinopyroxene, and plagioclase), we have studied the P–T conditions of formation of high-pressure (HP/UHP) rocks of the Maksyutov eclogite–blueschist complex in the South Urals. We have established its periodic evolution and have determined the specific thermodynamic parameters of mineral formation at each stage of its geodynamic history, from the conditions of crystallization of the protolith to the final stages of retrograde greenschist metamorphism. The new analytical data on the composition of coexisting phases confirm the high-pressure formation of eclogites present as numerous lenses, boudins, and interlayers among blueschist and feldspar–mica schists in the lower part of the complex. Thermobarometric calculations of metamorphism parameters were performed for the Grt + Cpx ± Pl + Qz paragenesis using a Grt–Cpx geothermometer and a Pl–Cpx–Qz geobarometer. Garnet in eclogites of the Maksyutov Complex, being conservative to changes in the P–T conditions, has a direct, reverse, or inverse chemical zoning. Under equilibrium of garnet with omphacitic clinopyroxene, this zoning records conjugate progressive and regressive P–T paths reflecting the thermodynamic conditions at the certain stages of the terrane evolution. Based on the data obtained, we have recognized at least four P–T stages of progressive metamorphic transformations of the Maksyutov Complex: (1) &gt;800–910 °C/~2.5–3.5 GPa; (2) 540–790 °C/2.0–3.5 GPa; (3) 410–690 °C/1.1–2.5 GPa; and (4) 310–520 °C/1.0–1.2 GPa. The estimated P–T parameters of the conjugate regressive stages of metamorphism are as follows: (1) 870–625 °C/3.5–2.5 GPa; (2) 745–615 °C/3.5–2.0 GPa; (3) 690–550 °C/1.5–1.0 GPa; and (4) 590–460 °C/1.2–0.6 GPa, respectively. The age data for the certain stages, along with the parameters of metamorphism, form a single P–T–t path of the complex, which determines the position of the gradient of the metamorphic field during the complex exhumation.
Oceanic Zircon as a Petrogenetic Indicator
Authors: Aranovich L.Ya. , Bortnikov N.S. , Borisov A.A. 
Published: July 2020

Abstract
—We present results of a study of the morphology, internal structure, and chemical composition of oceanic zircon, which show that zircon is a sensitive indicator of tectonic and physicochemical processes occurring in the lower oceanic crust. Crystallization of magmatic zircon in gabbroids is not an instantaneous process; it proceeds in the course of differentiation of parental melts in the tectonically active mid-ocean ridge (MOR) setting. The main geochemical indicator of crystallization differentiation during magma cooling is an increase in Hf content toward the zircon grain edge. Zoning is also observed in magmatic zircons from oceanic plagiogranites (OPG), but it is weaker, apparently because of the narrower temperature range of zircon crystallization in these rocks. The OPG zircons are depleted in REE as compared with the least altered magmatic zircons of gabbro, which is probably due to the formation of OPG during the partial melting of gabbro with the participation of concentrated water–salt fluid, a derivate of seawater, and due to the co-crystallization of zircon and apatite. High-temperature hydrothermal processes within slow-spreading MORs lead to a partial or complete recrystallization of zircon as a result of dissolution/redeposition. A significantly reduced cerium anomaly and the presence of microinclusions of xenotime, uranium and thorium oxides or silicates, and, sometimes, baddeleyite in zircon alteration zones indicate a reducing type and high alkalinity of the hydrothermal fluid. The fluid, a derivate of seawater, acquires these features during circulation near the axial zone of ridges as a result of phase separation in the system H2O–NaCl and interaction of the fluid with abyssal peridotites of oceanic core complexes. The estimated solubility of zircon in basic melts indicates that even near-solidus crystallization of zircon is highly unlikely in anhydrous basaltic melts but is possible in differentiates of deep-seated hydrous basic magmas. The Ti-in-Zrn geothermometer must be used with caution, because variations in the Ti content in zircon might be controlled not only by temperature but also by other factors, especially when mineral inclusions in zircon testify to a drastic change in its growth (dissolution) conditions. A geothermometer based on the distribution of Zr and Hf between zircon and the host rock has several advantages over indicators of the crystallization temperature of magmatic zircon that are based on the zircon saturation index and the content of Ti in zircon. It does not depend on the composition of melt and on the correct estimates of the SiO2 and TiO2 activity. In addition, reconstruction of the Zr and Hf fractionation trends during crystallization of zircon from granitoid melts makes it possible to evaluate the temperature of separation of more differentiated melt fractions.
Composition of Reduced Mantle Fluids: Evidence from Modeling Experiments and Fluid Inclusions in Natural Diamond

Published: July 2020

Abstract
—Experimental modeling in the C–O–H, C–O–H–N, and peridotite–C–O–H–N systems, combined with analyses of fluid inclusions in natural diamonds, is used to reconstruct the compositions of fluids that can be stable in the reduced mantle. Hydrocarbons (HCs) in the upper mantle can form either by reactions of carbonates with iron/wüstite and water or by direct hydrogenation of carbon phases (graphite, diamond, and amorphous carbon) interacting with reduced fluids. Carbon required for the formation of HCs can come from diamond, graphite, or carbonates. Mainly light alkanes are stable at the mantle pressures and temperatures in the C–O–H and C–O–H–N systems as well as in the peridotite–fluid system under ultrareduced to moderately reduced redox conditions at the oxygen fugacity from –2 to +2.5 lg units relative to the IW (Fe–FeO) buffer. Some oxygenated HCs can be stable in fluids equilibrated with carbonate-bearing peridotite. Ammonia and, to a lesser degree, methanimine (CH3N) are predominant nitrogen species in reduced fluids in the conditions of the subcratonic lithosphere or the Fe0-bearing mantle.
The presence of HCs as common constituents of reduced mantle fluids is supported by data on inclusions from natural diamonds hosted by kimberlites of the Yakutian province and from placer diamonds of the northeastern Siberian craton and the Urals. Fluid inclusions have minor amounts of H2O, methane, and other light alkanes but relatively high concentrations of oxygenated hydrocarbons, while the H/(H + O) ratio varies from 0.74 to 0.93. Hydrocarbon-bearing fluids in some eclogitic diamonds have high CO2 concentrations. Also, the fluid inclusions have significant percentages of N2 and N-containing species, Cl-containing HCs, and S-containing compounds.
Both the experimental results and the analyses of fluid inclusions in natural diamonds indicate that HCs are stable in the upper mantle conditions. The set of hydrocarbons, mainly light alkanes, might have formed in the mantle from inorganic substances. Further research should focus on the causes of the difference between experimental and natural fluids in the contents of methane, light alkanes, oxygenated hydrocarbons, and water and on the stability of N-, S-, and Cl-containing fluid components.
