It is widely accepted that natural gas is formed from thermal decomposition of both oil in reservoirs and, to a lesser extent, the organic matter in shales from which the oil was derived. But laboratory pyrolysis experiments on shales do not reproduce the methane-rich composition typical of most...
The Qiangtang Basin is located in the northern Qinghai–Tibet Plateau with an average altitude of more than 5000 m. So far, the surface gas manifestations have been poorly investigated due to difficulties accessing northern Tibet and its severe natural condition. In the present study, we report ...
δ 13C 2– δ 13C 3, along with natural gas plots, have proven to be a very effective tool in the genetic interpretation of natural gases from kerogen and oil cracking in the Tarim basin. Their combined application shows that two types of gas source can be identified in the Tazhong ...

Lead white is one of the most important pigments in human history, and its synthesis has promoted the development of art and cosmetics. The corrosion approach to synthesize lead white appeared in Greece during the fourth century BCE, and since then lead
Overall, more conclusive evidence, beyond molecular and bulk isotopic constraints, is needed to identify the origin of natural gas and extent of secondary microbial methane. In this study, we apply to methane the approach known colloquially as ‘clumped isotope geochemistry’ based on the natural ...
The δ13C values of natural gas alkanes are known to change with increasing molecular weight. In our previous studies (Dai, 1992, Dai et al., 1992, Dai et al., 2000a, Dai et al., 2000b), we have observed two types of carbon isotopic compositions: a normal order (i.e. δ13C1<...
