Different classes of organic phosphorus compounds have been identified in marine sediment samples taken at depth cores from pelagic, lower slope, and continental shelf depositional environments using solution solid-state magic angle spinning (MAS) 31P nuclear magnetic resonance (NMR) techniques. Phosphate esters as the major form all extracts separated bulk matter. Phosphonates, a P previously unreported sediments, were but one samples. The persistence both phosphate phosphonates suggests...

Five unique mineral assemblages that include the sulfates millosevichite, alunogen, anhydrite, tschermigite, coquimbite, voltaite, and godovikovite, as well halide salammoniac an unidentified phase, according to X-ray diffraction EDS data, were found encrustations on quartzofeldspathic sand sandstone adjacent coal-fire gas vents associated with underground coal fires in Wuda coalfield of Inner Mongolia.
Abstract The Biga Peninsula of NW Turkey is host to six major halloysite deposits in the Go¨nen, Yenice and Balya districts. Mineralization took place areas Permian limestone blocks where Triassic Karakaya Complex contact with early Miocene calc-alkaline volcanic rocks. Hypogene mineralization was controlled by intersection minor faults vicinity clay deposits. During Pleistocene, activity North Anatolian Fault (NAF) brought ascending geothermal solutions through fault zones surface, which...
Abstract. Long-term environmental research networks are one approach to advancing local, regional, and global science education. A remarkable number wide variety of operate around the world today. These diverse in funding, infrastructure, motivating questions, scientific strengths, sciences that birthed maintain networks. Some have individual sites were selected because they had produced invaluable long-term data, while other new span ecological gradients. However, all share two challenges....
Mineral weathering is a balanced interplay among physical, chemical, and biological processes. Fundamental knowledge gaps exist in characterizing the biogeochemical mechanisms that transform microbe-mineral interfaces at submicron scales, particularly complex field systems. Our objective was to develop methods targeting nanoscale by using high-resolution microscopy assess geochemical drivers of natural settings. Basalt, granite, quartz (53-250 µm) were deployed surface soils (10 cm) three...
Abstract Geomorphologists are quantifying the rates of an important component bedrock's weathering in research that needs wide discussion among soil scientists. By using cosmogenic nuclides, geomorphologists estimate landscapes’ physical lowering, which, a steady landscape, equates to upward transfers weathered rock into slowly moving hillslope‐soil creep. Since 1990s, these processes have been called “soil production” or “mobile regolith production”. In this paper, we assert importance...

Abstract Fixed nitrogen in illite-smectites (I-S) has been measured for Miocene shales from a Gulf of Mexico oil well. N values the <0.2 µm fraction increase with depth 150 ppm (1000 m) to maximum 360 (3841 m). This is coincident illitization 41% I I-S 75% I-S. Below 3841 m, fixed decrease 190 (4116 while maintained slight 77 82%. The changes increasing are consistent notion that proceeds via both transformation and dissolution/ precipitation reaction mechanisms. trend decreasing illitic...
Silicification of microbial communities is the most pervasive form mineralization in two terrestrial hot springs Uzon Caldera. X-ray diffraction and electron microscopy reveal a diverse sinter mineral assemblage dominated by opal-A with accessory sulfur, sulfides, alunite group minerals, oxides, oxyhydroxides. Aluminum laminations (reported for first time) noted one deposit may slow transformational rates enabling mineralized remnants to exist longer rock record. Although preservation forms...
