Petrologic and geochronological constraints on the polymetamorphic evolution of the collisional granites, Araçuaí Orogen (SE Brazil) by SANDRO MAURI, MARILANE G. MELO, CRISTIANO LANA, RODSON A. MARQUES

“…Preservation of the mineral assemblage A1 (garnet-biotite-plagioclase-K-feldspar-quartz-ilmenite-melt) indicates that most of the generated melt was lost from these rocks at or near peak metamorphic conditions. A second metamorphic event (M2) is characterized by growth of a second generation of garnet in preserved A2 assemblage (garnet-sillimanite-biotite-plagioclase-K-feldspar-quartz-ilmenite-melt). …”

Conodont biostratigraphy of a Carboniferous–Permian boundary section in siliceous successions of pelagic Panthalassa revealed by X-ray computed microtomography by Shun Muto, Satoshi Takahashi, Masafumi Murayama, Masafumi Murayama

“…X-ray computed microtomography, while not widely used in biostratigraphic studies until now, allows us to visualize fossils that are impossible or difficult to extract from host rocks due to poor preservation. In this study, we applied this method on conodonts from a pelagic chert–claystone succession in Okoshizawa, Iwaizumi Town, Northeast Japan, using a laboratory-based X-ray microscope. …”

Genesis of the Halılar Metasediment-Hosted Cu-Pb (±Zn) Mineralization, NW Turkey: Evidence from Mineralogy, Alteration, and Sulfur Isotope Geochemistry by Demet Kiran Yildirim

“…The study area represents local Cu-Pb with some Zn brecciated-stockwork vein type mineralization along the NE–SW fault gouge zone at the lower boundary of the Sakarkaya and Düztarla granitoid rocks. Two main zones, consisting of sericite–quartz–chlorite ± kaolinite ± pyrite (i.e., zone-1) and calcite–epidote–albite ± chlorite ± sericite (i.e., zone-2), were observed within the central ore mineral zone at the mining site. …”

Groundwater quality assessment in the ophiolite area of (BAER-BASSIT) in north-western Syria by أريج عدره, محمد هشام أبظلي, عبدالله افرنجي

“…The results showed that groundwater is highly influenced by the weathering of ophiolitic rocks which is slightly alkaline and shows (Mg HCO3) water  type as a major type using Piper plot.The concentration of magnesium and bicarbonate ions were predominant in most water samples and  exceeding maximum permissible limit according to the Syrian standards.While the concentrations of ions (Ca2+، K +، Na +) (Cl-، SO42-، NO3-) were within the limits of drinking water.  …”

Simple house foundation models in potential landslide area (case study: Bojong Koneng Village, Babakan Madang Sub-District, Bogor District) by Hasanah Mauliyatul, Asokawati Fajrina Citra, Elvirandra Laura, Fansuri Muhammad Hamzah

“…Bogor Regency is a land area that has varied geomorphological conditions, mostly in the form of plateaus, hills and mountains with constituent rocks dominated by volcanic eruptions. This study was conducted to determine the topographic and geotechnical conditions at the Bojong Koneng location to determine the prediction of landslide areas, obtain the foundation planning criteria for simple houses in vulnerable areas, and design a foundation model suitable for simple houses in erosion-prone areas based on field survey in Curug Village, Bojong Koneng Village, Babakan Madang, Bogor Regency, West Java With a slope ranging from 10°-25° sloping to the north which is a soft black clay layer with the slope of the layer in the direction of the slope. …”
