Geochemical characteristics of natural gases in the Sichuan basin
Chinese Journal of Geochemistry, 1985The Sichuan basin is one of the largest gas-oil-bearing basins in China. Ool and. gas pools occur in Mesozoic, Paleozoic and Proterozoic strata in this basin, with natural gases being dominant.

The application of prestack inversion in Guang'an area, Sichuan Basin
SEG Technical Program Expanded Abstracts 2007, 2007In recent years, the Xujiahe formation of the Upper Triassic in the Sichuan Basin has become an important objective for gas exploration. This is especially true in the Xu6 Section where sandstone has developed, but not all sandstones are effective reservoirs.

Characteristics and origins of carbonaceous aerosol in the Sichuan Basin, China
Atmospheric Environment, 2014Abstract The Sichuan Basin is a low visibility area in southwest China, where the hilly and basin topography, plus humid and stagnant weather, lead to unique pollution patterns. To identify the characteristics and sources of carbonaceous aerosols, one-year record of 24-h PM2.5 samples were analyzed for organic carbon (OC) and elemental carbon (EC ...

Implications of ozone transport on air quality in the Sichuan Basin, China
Environmental Science and Pollution ResearchOzone pollution is formed through complex chemical and physical processes closely associated with emissions, photochemical reactions, and meteorological conditions. The objective of this study is to quantify the contributions of meteorological chemical formation, vertical transport, and horizontal transport to air quality during spring and summer in ...

Lower Cretaceous paleosols and paleoclimate in Sichuan Basin, China
Cretaceous Research, 2016Abstract Abundant Lower Cretaceous (Berriasian–Hauterivian) paleosols have been recognized in the Sichuan Basin, along with the preserved pedogenetic features, e.g., soil horizons, soil structure, root traces and pedogenic nodules. Chemical, geochemical and mineralogical analyses were used to examine the paleosols.

The Qiongzhusi-Dengying petroleum system in the Sichuan Basin, China
AAPG BulletinABSTRACT In the Sichuan Basin there is abundant evidence in the lower Cambrian Qiongzhusi Formation and Ediacaran (upper Sinian) Dengying Formation for the existence of the oldest petroleum system in China. Here, we discuss the essential elements of the petroleum system—source rock in the Qiongzhusi Formation and reservoir rock in the

The Deep Structure Feature of the Sichuan Basin and Adjacent Orogens
Acta Geologica Sinica - English Edition, 2015AbstractThe basin‐mountain system in the Sichuan Basin (SCB) reflects the main tectonic activity and the orogenic denudation in this region. The seismic probing work reveals the deep structure of the basin‐mountain system. The seismic work was re‐sampled to the Moho depth and the sedimentary thickness as well as the P‐wave velocity‐depth function to ...

Timing and provenance of loess in the Sichuan Basin, southwestern China
Palaeogeography, Palaeoclimatology, Palaeoecology, 2010Abstract Loess-like sediments (locally called the Chengdu Clay) are widely distributed in the Sichuan Basin, at the eastern margin of the Tibetan Plateau (TP), southwest China. Geomorphology, sedimentology/pedology, grain size distributions and quartz oxygen isotopic ratios collectively demonstrate the aeolian origin of the Chengdu Clay and its main ...

Paleozoic shale gas resources in the Sichuan Basin, China
AAPG Bulletin, 2018ABSTRACT The Sichuan Basin, China, is commonly considered to contain the world’s most abundant shale gas resources. Although its Paleozoic marine shales share many basic characteristics with successful United States gas shales, numerous geologic uncertainties exist, and Sichuan Basin shale gas production is nascent.
