Reservoir characteristics and the occurrence mechanism of shale gas outside Sichuan Basin are research hotspots normally pressured shales in China. Taking on Anchang syncline from periphery as an example, X-ray diffraction, organic geochemistry, rock physical experiments were carried out to analyze reservoir their main geological controls shales. The mineralogical results show that studied main...

As the world's urban population continues to grow, it becomes increasingly imperative to understand the dynamic interactions between human activities and the urban environment. The development of urban environmental geochemistry has yielded a significant volume of scientific information about geochemical phenomena found uniquely in the urban environment, such as the distribution, dispersion, an...

The 9th national conference on applied geochemistry in China will be held Chengdu, Sichuan province, October 2023, hosted by the committee of geochemistry, Chinese Society for Mineralogy, Petrology and Geochemistry (CSMPG) [...]

We examined the use of dC, TOC and C/N geochemistry of sedimentary organic matter to reconstruct former sea levels and paleoenvironments in the absence of suitable microfossil data. The modern distribution of dC, TOC and C/N of 33 vegetation and 74 surface sediment samples collected from four coastal wetlands in the Thames Estuary and Norfolk, UK are described. The dC, TOC and C/N geochemistry ...

Ž . We report Inductively Coupled Plasma Mass Spectrometer ICP-MS trace element concentration data for 21 elements in Ž 51 basaltic glasses recovered from 58 stations along a 1500-km segment of the equatorial mid-Atlantic Ridge MAR; 58N to . Ž 58S . Isotope systematics of these glasses revealed mixing between two isotopically distinct Schilling, J.-G., Hanan, B.B., McCully, B., Kingsley, R.H., ...

Reactive iron (Fe) oxides and sheet silicatebound Fe in reservoir rocks may affect the subsurface storage of CO2 through several processes by changing the capacity to buffer the acidification by CO2 and the permeability of the reservoir rock: (1) the reduction of threevalent Fe in anoxic environments can lead to an increase in pH, (2) under sulphidic conditions, Fe may drive sulphur cycling and...

As an unconventional petroleum reservoir, the volcanic reservoir is essential for finding large-scale oil and gas reserves in deep sedimentary basins. Based on basin modeling, organic geochemistry, petrology, this study evaluates exploration potential of Carboniferous volcanic-petroleum system Jimsar Sag southeastern Junggar Basin. The source rocks area were developed Lower Songkharsu Formation...
