Great progress has been made in the exploration of tight sandstone gas resources Kuqa depression. Dibei structural belt, which proves previously unproven favorable area for gas. The physical properties, controlling factors, and characteristics from Ahe (J1a) Formation reservoir are analyzed. results show that J1a is mainly feldspar lithic sandstone, with low porosity (average 9.1%) permeability...

Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembour...

Volcanism is a dominant natural source of mercury (Hg) to the atmosphere, biosphere, ocean and sediments. In recent years, sedimentary Hg contents have emerged as tool reconstruct volcanic activity, particularly activity (subaerially emplaced) large igneous provinces in geological deep time. More specifically, has shown potential useful proxy illuminate previously elusive impact such large-scal...

Abstract The deepest part of the global ocean, hadal trenches, are considered to act as depocenters for organic material. Relatively high microbial activity has been demonstrated in sections some but deposition dynamics thought be spatially and temporally variable. Here, we explore sediment characteristics in-situ benthic oxygen uptake along two trenches with contrasting surface primary product...
