Abstract: The occurrence and characteristics of volcanic rocks, organic reefs, gypsum-salts, metal (non-metal) deposits, formation waters in Tarim basin are discussed. The results show that there exist active deep geofluids in the basin. Pb-Sr-Nd isotopic systematics of the bitumen and trace elements of the crude oils support the deep inorganic origin of the bitumen and crude oils. The deep crust structure of the basin shows that petroleum can be formed in the low velocity-high conductive layer by Fischer-Trupsch synthetic reaction.

Key words: volcanic rock, organic reef, evaporate bed, deep zone, fluid, trace element, asphalt, inorganic origin
