Early-crystallizing chromian spinel(Cr-spinel) in the Nagqu ophiolite has high Os and low Re contents,and it is resistant to alteration during serpentinization,weathering and metamorphism.The chemical composition of p...
In 1997 and 1998, hundreds of specimens of megascopic carbonaceous compressions or algal fossils were found from - 1800-million-year old Changzhougou Formation, which is the lowermost unit of the latest Palaeoproteroz...
Carbons pyrolyzed at temperature ranging from 500℃ to 1 000℃ are premising materials for high-energy density lithium batteries. These carbons not only possess a capacity higher than the theoretical value of graphite...

Application of the mixing-line model for two components has proved successful to the dating of carbonaceous samples and been extended to the domain of uranium-series chronology, as weU as to the Late Quaternary record...
During the past two decades, great progress has been made in the uranium-series disequilibrium studies and the results have been widely applied to the dating of the Pleistocene pure carbonate deposits with great succe...
