The fate of giant Silurian paleo-reservoirs in Tarim Basin
- Guangzhou Institute of Geochemistry (China); and others
Tarim Basin is located in the south part of the Xinjiang Yugur autonomous region of China, between Tianshan and Kunlun mountains. Tarim Basin is the largest petroliferous sedimentary basin in China, with a total area of 560,000 km{sup 2}. Within the past five years` exploration, it was revealed that there occur widely tar sands and heavy oils in the Silurian formation in North and Central uplifts of Tarim basin in a huge volume. Based on the geochemical data including distribution of biological markers, this talk will discuss how these tar sands and heavy oils were formed by destruction and degradation of giant Silurian reservoirs. It will also be pointed that these tar sand bitumen have made important contribution to petroleum accumulation as an unique hydrocarbon source in Tarim basin.
