Tectonic evolution of the Sichuan Basin, Southwest China
Earth-Science Reviews, 2021Abstract Surface deformation in continental interiors is typically coupled to processes at depth. However, in the Sichuan basin, east of the Tibetan Plateau, recent seismic data detect Neoproterozoic subduction and rifts, indicating long-term tectonic quiescence of the basement. The Sichuan basin is characterized by two episodes of weak extension and

The water footprint of hydraulic fracturing in Sichuan Basin, China
Science of The Total Environment, 2018Shale gas is likely to play a major role in China's transition away from coal. In addition to technological and infrastructural constraints, the main challenges to China's sustainable shale gas development are sufficient shale gas production, water availability, and adequate wastewater management.

Characteristics of air pollution in different zones of Sichuan Basin, China
Science of The Total Environment, 2018Sichuan Basin, located in southwest China, has been ranked as the fourth of heavily air polluted regions in China partly due to its deep mountain-basin topography. However, spatial-temporal distribution of air pollution over the basin is still unclear due to the lack of monitoring data and poor knowledge. Since January 2015, six criteria air pollutants

Aerosol optical properties and chemical composition apportionment in Sichuan Basin, China
Science of The Total Environment, 2017PM2.5 and its major chemical components, and light scattering (σscat) and absorption (σabs) coefficients were measured in Chengdu (CD) and Chongqing (CQ) in Sichuan Basin, from October 2014 to July 2015. Annual mean PM2.5, σscat and σabs were 67.0±43.4μgm-3, 421.4±290.1Mm-1 and 36.7±26.4Mm-1, respectively, in CD, and annual mean PM2.5 and σabs were 70 ...

Natural gas accumulation in the basin–mountain transition zone, northwestern Sichuan Basin, China
Marine and Petroleum Geology, 2021Abstract The basin–mountain transition zone is an important area for hydrocarbon exploration. To better understand the process and mechanism of hydrocarbon accumulation in this area, the middle Permian Qixia Formation at the piedmont of the Longmenshan Mountains, northwestern Sichuan Basin, China, was investigated.

Origin of Subsurface Brines in the Sichuan Basin
Groundwater, 1997Abstract Subsurface brines in the Sichuan Basin occur within sedimentary rocks ranging in age from Sinian to Cretaceous, especially within rocks of Triassic age. The chemical and isotopic compositions of the brines and general geological considerations suggest that the Sichuan Basin brines are derived from waters of different origin ...

Water Availability for Shale Gas Development in Sichuan Basin, China
Environmental Science & Technology, 2016Unconventional shale gas development holds promise for reducing the predominant consumption of coal and increasing the utilization of natural gas in China. While China possesses some of the most abundant technically recoverable shale gas resources in the world, water availability could still be a limiting factor for hydraulic fracturing operations, in ...

Northeastward propagation of nocturnal precipitation over the Sichuan Basin
International Journal of Climatology, 2020AbstractThe Sichuan Basin (SCB) is located to the east of the Tibetan Plateau (TP) and features nocturnal precipitation. This study explores spatial variation of nocturnal precipitation during the warm season over the SCB using high spatiotemporal resolution merged precipitation products from 2008 to 2017.
