Abstract The episode of widespread organic carbon deposition marked by peak black shale sedimentation during the Palaeoproterozoic is also reflected in exceptionally abundant graphite deposits this age. Worldwide anoxic/euxinic sediments were preserved as a deep crustal reservoir both carbon, and sulphur accompanying pyrite, commonly >1 wt %. carbon- sulphur-rich crust interacted with mafic ...

Abstract Mountain Pass is the site of most economically important rare earth element (REE) deposit in United States. Mesoproterozoic alkaline intrusions are spatiotemporally associated with a composite carbonatite stock that hosts REE ore. Understanding genesis and magmas an essential scientific goal for society which critical minerals high demand will continue to be so foreseeable future. We p...

Current research on diagenesis and its evolution focuses mainly sandstone reservoirs. Conventional oil gas reservoir observation techniques for characterizing shale reservoirs are limited, comprehensive nanoscale pore variations, of reservoirs, especially immature low-maturity marine is relatively scarce. To reveal the shale, geochemical mineral analyses, quantitative characterization structure...
