Cover Story：Diagrammatic geological section of the Lower Member of the Upper Jurassic Tukari Formation in the Coqen Basin of Tibet. Based on the study of the coral fossils, researchers redefined the carbonate rock in Gechangchayu area at Baoji Town of Bange County as belonging to Upper Jurassic, which can be correlated with the Upper Jurassic carbonate rock of Arab Formation that is one of the major oil-producing horizon in the Tethys oil and gas bearing tectonic do-main and also the major oil-producing horizon of the Ghawar Oilfield, the largest oilfield in the world. The first definition of the Upper Jurassic carbonate rock strata in the Coqen Basin of Tibet has provided solid and important scientific foundation for reevaluating the prospect of oil and gas resources in Tibet and forecast-ing the strategic position of Tibetan energy resources. The newest research result and progress achieved by the research group led by Professor JI Zhan-sheng, Chinese Academy of Geological Sciences and Institute of Geology of CAGS, see pp. 385-473 of this issue for the special column.
