Hydrochemistry of the lakes in the southern Badain Jaran Desert and its paleosalinity reconstruction

China Geology
: The reconstruction of paleohydrology, especially paleosalinity, is an important component of paleoenvironmental research. Researches on the modern characteristics of lake water chemistry and the relationship between lake salinity and hydrochemistry are

Oyster shells as archives of present and past environmental variability and life history traits: A multi‐disciplinary review of sclerochronology methods and applications

Limnology and Oceanography Letters, Volume 10, Issue 2, Page 179-199, April 2025.
Abstract Oysters inhabit a variety of coastal and deep‐sea settings over a wide latitudinal range and have a role as ecosystem engineers. They also represent an important food source for humans since hunter‐gatherer times, which motivates interest in using oyster shells as environmental and life history archives.

Source Rock Characteristics and Petroleum‐Geological Significance of Paleogene Niubao Formation in the Nima Basin, Central Tibet, China

Energy Science &Engineering, Volume 13, Issue 2, Page 878-893, February 2025.
ABSTRACT Nima Basin, as a typical Tethys area, is a Cenozoic oil‐bearing basin in the middle of Qinghai‐Tibet Plateau, which is expected to become an important target for petroleum exploration. The main controlling factors and models of organic matter enrichment are not yet clear.

Quantitative reconstruction of the paleosalinity in the Daihai Lake, Inner Mongolia, China

Chinese Science Bulletin, 2001
Ostracods are small bivalved aquatic crustaceans. They secrete shells of low-Mg calcite that are often preserved in lake sediments. Recent work has shown that the uptake of trace elements (especially Mg and Sr) into the shell may be a function of the salinity and temperature of the host water. We measured Sr/Ca ratios in living ostracod valves from the
