Early oil charging from Sinian shales in Ordovician carbonates of the Tabei Uplift, Tarim Basin: Evidence from biomarkers

Petroleum Research
Despite over 40 years of exploration focusing on the deep to ultra-deep Ordovician carbonates as major hydrocarbon targets in the Tarim Basin, the identification of their source rocks remains elusive.

Origin and age of Mn deposits of the Nantuo Formation in the Sinian System

Chinese Science Bulletin, 1997
THE tillites in the Nantuo Formation of the Sinian System is considered contemporary with theVaranger ice age. The manganese deposits in the Nantuo Formation are most suitable to isotopic dating and may record the precious information on paleo-ocean chemistry.
