Preliminary analysis of sedimentary characteristics and facies model of M-II layer in Kazakhstan Oilfield A [PDF]
E3S Web of Conferences, 2022 The lithologic melange accumulation of areskum formation in akshabluk area is one of the key strata in exploration. Its basement inheritance controls the whole process of Jurassic sedimentation, and the filling and leveling gradually reduces the terrain ...

Microplastics affect sedimentary microbial communities and nitrogen cycling [PDF]
Nature Communications, 2020 AbstractMicroplastics are ubiquitous in estuarine, coastal, and deep sea sediments. The impacts of microplastics on sedimentary microbial ecosystems and biogeochemical carbon and nitrogen cycles, however, have not been well reported. To evaluate if microplastics influence the composition and function of sedimentary microbial communities, we conducted a

Phanerozoic cycles of sedimentary carbon and sulfur [PDF]
Proceedings of the National Academy of Sciences, 1981 A reservoir model of a Recent steady-state sedimentary system in which the reduced sulfur and oxidized sulfur reservoirs were coupled with the oxidized carbon and reduced carbon reservoirs was constructed. The time curve of the sulfur isotope ratios of the sedimentary sulfate reservoir was used to drive the model back to the beginning of ...

Orbital frequencies in the carbonate sedimentary record: distorted by diagenesis? [PDF]
, 2004 The most important archive of Earth’s climate change through geologic history is the sedimentary rock record. Rhythmic sedimentary alternations are usually interpreted as a consequence of periodic variations in the orbital parameters of the Earth.

High-frequency East Asia monsoon variability during 115000 - 93000 a BP in Northern China
Terrestrial, Atmospheric and Oceanic Sciences, 2021 The FGS5c-d segment of the Fanjiagouwan section is located in the Salawusu River Valley on the southeast margin of the Mu Us Desert in China. It contains 17 sedimentary cycles consisting of aeolian dune sands and lacustrine facies during 115000 - 93000 a
