title: Seasonality of tropical airborne algae: a 16-month study based on high-throughput sequencing in the Hawaiian Islands

description: The airborne environment is a critical juncture linking terrestrial and aquatic habitats, yet the algae of this environment are not well-characterised and understood. The goal of this study was to examine seasonality patterns of airborne algae in a tropical environment. Airborne algae were collected monthly in spore traps on a building rooftop on the island of Oʻahu, Hawaiʻi, U.S.A. from December 2015 to March 2017. Metabarcoding of Universal Plastid Amplicon (UPA) and 16S ribosomal RNA (rRNA) markers was used to characterise the algal diversity in the samples relative to meteorological data. Modelled back-trajectories of air masses arriving at the site demonstrated that months with the highest rainfall corresponded to those with the strongest tradewind signal. Thirty airborne algal Exact Sequence Variant (ESV)s were identified using the UPA marker including Cyanobacteria (20), Chlorophyta (4), Streptophyta (3), Chrysophyceae (1), Synurophyceae (1), and unknown Stramenopila (1). Forty-four ESVs were identified using the 16S marker and consisted of Cyanobacteria (43) and plastids of Streptophyta (1). The number and diversity of sequence reads obtained varied strongly both among samples for a given time period and from month to month. Highest rainfall and air temperatures corresponded to months with the largest cyanobacterial relative abundance according to the UPA marker. Although cyanobacteria were the most common group identified using the 16S marker, the dominant cyanobacterial taxon varied by month. Diversity or abundance patterns were not explained by meteorological conditions, which may be due to the relatively small annual amplitude in conditions in the Hawaiian Islands.

title: Mineralogy and character of the Liikavaara Östra Cu-(W-Au) deposit, northern Sweden

description: The Liikavaara Östra Cu-(W-Au) deposit is situated close to the operating Aitik Cu-Au mine in northern Sweden. It is scheduled for production in 2023. Modern geological descriptions of the deposit are lacking though knowledge of geological and mineralogical details prior to operation is beneficial to avoid surprises. In this study, petrological, mineralogical and geochemical investigations of the wall rocks, host rock and mineralisation, and zircon U-Pb analysis of a footwall granodioritic intrusion were carried out. The mineralisation is hosted by quartz±tourmaline-calcite veins, calcite veins and aplite dykes that cross-cut biotite-amphibole schists and gneisses. The wall rocks to the ore are metavolcaniclastic rocks of basaltic to andesitic composition. A granodiorite intrusion occurs in the footwall. The mineralisation is mainly chalcopyrite, pyrrhotite and pyrite with some sphalerite, galena, scheelite, molybdenite and magnetite. It shows slight enrichments in Au, Ag and Bi. Gold and Ag occur as electrum and Ag also in hessite and an Ag-sulphide. The Bi mineralogy includes native Bi, Bi-tellurides and Bi-sulphides. These minerals are found as inclusions, along the borders of and in cracks in chalcopyrite, pyrite, pyrrhotite, sphalerite, molybdenite and quartz. The footwall granodiorite intrusion was dated at 1.87 Ga. It is suggested here to be the source for ore genesis based on its spatial relation to the mineralisation, as well as on high-salinity fluids and metal composition of the ore. The aplite dykes may have acted as pathways for the magmatic hydrothermal fluids that carried the metals from the intrusion to the host rock.

title: High-resolution event stratigraphy (HiRES) of the Silurian across the Cincinnati Arch (USA) through integrating conodont and carbon isotope biochemostratigraphy, with gamma-ray and sequence stratigraphy

description: Silurian strata within the tristate area of Indiana, Ohio, and Kentucky have been thoroughly studied for well over a century. Due to rapid facies changes throughout the region numerous lithostratigraphic terminologies were established, many of which were difficult to correlate even over short distances. Recently these stratigraphic complexities have received renewed interest due to advancements in bio-, chemo-, and sequence stratigraphy that greatly improved our understanding of the tristate area. These improvements had significant implications for our ability to correlate Rhuddanian through lower Sheinwoodian strata between the Appalachian and Illinois basins and allowed unified nomenclatural and sequence stratigraphic hierarchies for this interval to be developed across the Cincinnati Arch. Recent advancements in regional chronostratigraphy of Silurian strata, however, highlight several discrepancies with regards to the 3<sup>rd</sup>- and 4<sup>th</sup>-order sequence stratigraphic hierarchies assigned within these basins. In an effort to alleviate these points of disagreement, we contribute new δ<sup>13</sup>C<sub>carb</sub> chemostratigraphic and sequence stratigraphic analyses of a basinward Appalachian section from Scioto County, Ohio, spanning upper Telychian through Gorstian strata assigned to the Estill through Tymochtee formations, complemented by gamma-ray core scans for localities traversing northwestward from the sampled core section into western Ohio. These new data allow unified nomenclatural and sequence stratigraphic hierarchies to be developed throughout the region for strata spanning the upper Telychian through Gorstian stages. Additionally, these findings highlight a significant shift in the primary sites of sediment accommodation during the studied depositional interval.

title: Lituitid cephalopods from the upper Darriwilian and basal Sandbian (Middle–Upper Ordovician) of Estonia

description: Cephalopods of the order Lituitida Starobogatov, 1983 from the late Darriwilian and early Sandbian strata of Estonia are revised herein. During that time, the lituitids reached their peak abundance and were among the key components of cephalopod faunas on Baltica, as well as in other mid- and low-latitude palaeogeographic locations. The Estonian lituitids mostly come from localities representing more off-shore environments with deeper-water sedimentation in the Middle Ordovician. This supports previous assumptions that lituitids preferred pelagic environments and were capable of long-distance migration. In the studied lituitid collection, two genera were identified – <i>Lituites</i> Bertrand, 1763 and <i>Ancistroceras</i> Boll, 1857. Three species – <i>Ancistroceras ristnensis</i> sp. nov., <i>Ancistroceras vahikuelaensis</i> sp. nov. and <i>Lituites nehatuensis</i> sp. nov. – were newly established. However, species determinations were often hindered by high intraspecific variability and fragmentary preservation. Investigation of cameral deposits using median sections showed that: connecting rings in chambers with deposits are commonly broken or missing; oriented fragments of connecting rings are present, sometimes overgrown by primary deposits; several generations of primary deposits can be developed; simultaneous presence of both broken and intact connecting rings in the same specimen is usual. These observations elucidate the formation of cameral deposits in lituitids. Currently, this process is explained either by passive deposition from cameral fluids, or active secretion by cameral mantle. The evidence collected herein from Estonian lituitids reveals, however, that both modes of formation might have occurred successively during the lituitid ontogeny and that a gradual, life-time destruction of connecting rings was possibly involved.

title: Zircon U–Pb-Hf isotope data in eclogite and metagabbro from southern Sweden reveal a common long-lived evolution and enriched source

description: Several orogenies have shaped the bedrock of southern Sweden. While mafic intrusions represent significant sources of information for reconstructing geodynamics and crustal evolution, the characterization of the various generations of such intrusions in Sweden remains limited. We report <i>in situ</i> zircon U–Pb ages and Hf isotope data from a Fe-Ti eclogite and a coronitic metagabbro from the Eastern Segment in southern Sweden. Crystallisation ages at 1683 ± 17 Ma of the eclogite suggest affiliation with the surrounding 1730–1660 Ma Transscandinavian Igneous Belt intrusions that dominate the Eastern Segment. Secondary zircon growth and Pb-loss in the eclogite sample at 1459 ± 44 Ma and the crystallisation of the metagabbro at 1431 ± 26 Ma overlap and are related to magmatic activity during the Hallandian orogeny. Zircon Hf isotope signatures with chondritic and sub-chondritic values at ~1683 Ma and ~1431 Ma, respectively, correspond to an enriched (or mildly depleted) source in line with a “Mixed Svecofennian Crustal Reservoir”. These isotope signatures are more enriched than those in the surrounding gneisses. Zircon isotope data from the herein analysed zircon grains indicate that the eclogite and metagabbro had an enriched mafic source in the mid to lower crust, or within the subcontinental lithospheric mantle below Fennoscandia.

title: Design and performance analysis of a micro-displacement worktable based on flexible hinges

description: To investigate the maximum output displacement of the flexible hinges and examine the performance of the flexible hinges. The FEM (Finite Element Method) model of flexible hinges was established. AISI 1045 steel was selected as the material of the model. Figure 7 shows the relationship between the stress of the flexible hinges and the input displacement. The output displacements of three flexible hinges are calculated using FEA. When the stress of the danger points is less than allowable stress, it can be seen input displacement and output displacement have linear relationships. The results are shown in Figure 8 and Figure 9. The flexible hinges were tested on the test platform. Then the experimental results are compared with simulation results. Figure 11 shows the experimental results of the X(→) and Z(→) direction of flexible hinge A. The experimental results of the flexible hinge B and hinge C are shown in Figure 12. The flexible hinge assembly was tested on the experimental platform. The experimental results for the direction of X(→) and Z(→) of the flexible hinge A are shown in Figure 13a. The experimental results for X(︵) and Z(︵) displacement of the flexible hinge B and hinge C assembly are shown in Figure 13b.
