TL;DR: In this article, the authors analyzed three major hydrocarbon bearing intervals in the Lunnan lower bulge for their stable carbon isotopes and molecular biomarkers and concluded that the recently discovered deep (6500m) eastern Lungu giant Ordovician gas condensate pool with an estimated reserve of 723 million bbl oil equivalent is a secondary hydrocarbon accumulation derived from the mixing of an early formed oil and a late formed gas.

TL;DR: In this article, the authors examined factors controlling biogenic gas generation in the Quaternary Qaidam Basin of China, and found that meteoric water invasion was important in stimulating microbial activity.

TL;DR: Based on tracers of different diagenetic stages, Wang et al. as mentioned in this paper examined various rocks of the Quaternary gas-producing province in the Sanhu Depression, Qaidam Basin, and identified the possible source rocks for the biogenic gas through investigating the special minerals, characteristics of organic matter, and their inter-relationship.

TL;DR: In this paper , two episodes of magmatism with zircon U-Pb ages of 2.46 Ga and 2.0 Ga were studied in the Jinpan Complex in the north Yangtze Craton of South China.

TL;DR: A field-based geochemical study of amphibolites with extremely high Nb/Ta ratios (up to 98.7) and enriched HREE concentrations was performed in this paper , which revealed the progressive leaching and fractionation of HFSE and rare earth elements by the hydrothermal fluids.
