AN id=EnChDivSummary name="EnDivSummary">The outcrop and core data show that there have developed wide distribution of tectonic hydrothermal dolomitization of Lower Palaeozoic in Tarim Basin. The research show that there have obvious difference with Devonian hydrothermal dolomite in Seaga Basin. The extensive development of the Permian magmatic thermal event of Tarim Basin maybe is the main causes of tectonic hydrothermal dolomite. The reservoir related to tectonic hydrothermal dolomite are mostly high-quality reservoir, which distribution are closely related to fracture and unconformity, will be a favorable target for oil and gas exploration.
