Mass movement susceptibility mapping using satellite optical imagery compared with InSAR monitoring: Zigui County, Three Gorges region, China [PDF]

open access: yes, 2010
Mass movements on steep slopes are a major hazard to communities and infrastructure in the Three Gorges region, China. Developing susceptibility maps of mass movements is therefore very important in both current and future land use planning.

Microscopic Pore Structure Characteristics and Genesis of Low Resistivity Reservoirs: A Case Study of the Wufeng and Longmaxi Formations in the Changning Area, Sichuan Basin

open access: yesEnergy Science &Engineering, Volume 13, Issue 12, Page 5910-5923, December 2025.
1. Organic matter graphitization forms highly conductive carbon networks, significantly reducing shale resistivity. 2. Major and trace elements further enhance conductivity through electron transfer and electrochemical reactions. ABSTRACT This study investigates the micro‐pore structure characteristics and genesis of low‐resistivity reservoirs in the ...

Palaeoceanographic controls on spatial redox distribution over the Yangtze Platform during the Ediacaran–Cambrian transition [PDF]

open access: yes, 2016
The Ediacaran–Cambrian interval was an eventful transitional period, when dynamic interactions between the biosphere and its physical environment allowed the Earth System to cross into a new state, characterized by the presence of metazoans, more equable

A new rock-based definition for the Cryogenian Period (circa 720 - 635 Ma) [PDF]

open access: yes, 2016
The Cryogenian Period was first established in 1988 along with other Precambrian eon, era and period-level subdivisions that were defined numerically by Global Standard Stratigraphic Ages (GSSAs).

Dynamic reconstruction of the hydrocarbon generation, accumulation, and evolution history in ultra-deeply-buried strata

open access: yesFrontiers in Earth Science, 2022
The evolution mechanism of hydrocarbons in ultra-deeply-buried and ultra-old strata is the core issue of petroleum geology moving towards Deep Earth. Reconstructing the evolutionary history of ultra-deeply-buried hydrocarbons is the key to shedding light
