Mantle processes control plate tectonics and exert an influence on biogeochemical cycles. However, the proportion of mantle sampled in-situ is minimal, as it buried beneath igneous crust sediments. Here we report lithological characteristics two sections from embryonic ocean drilled by International Ocean Discovery Program (IODP) in Tyrrhenian Sea. Contrary to at Mid Ridges (MORs) hyperextended passive margins, our findings reveal exceptionally heterogeneous fertile lithologies, ranging...
Abstract Tungsten deposits are usually associated with granitic intrusions that record a long and complex evolution of the magmatic-hydrothermal system. However, genetic link between tungsten mineralization remains unclear. The Xihuashan deposit in South China, an important vein-type wolframite deposit, is closely greisen multi-phase intrusive activity produced biotite granite, two-mica muscovite granite. From granite to micas vary from siderophyllite lithian siderophyllite, decreasing K/Rb...
Hydrothermal fluids enriched in hydrocarbons of apparent abiotic origin vent from Fe‐Ni sulfide bearing chimney structures on the seafloor at slow spreading mid‐ocean ridges. Here we show results a hydrothermal experiment using carbon isotope labeling techniques and mineral analytical data that indicate pentlandite ((Fe 2 Ni 7 )S 8 ) enhances formation C 3 alkanes, while also contributing to other more complex hydrocarbons, such as alcohols carboxylic acids. ToF‐SIMS reveal existence...
Abstract Hydrogen gas accelerates hydrocarbon generation, but little is known about its distribution and origin in petroliferous basins, which has hindered the further exploration. Taken Jiyang Depression eastern China as an example, this study collected natural from different tectonic units, analyzed various geochemical characters including contents, carbon hydrogen isotopic composition. The result shows that: (1) widespread distributed, content very low, typically ranges 0.01% to 0.1%...
