Prospects for Petroleum Exploration of Altun Foothill Belt in Western Qaidam Basin

Abstract

Abstract: Altun foothill belt of western Qaidam basin is regarded as a major pre-exploration belt with abundant petroleum resources, high geo-logical evaluation,, low explorative degree and great potentials for prospecting. The study shows that there exist multiple depositional systems, complex structural deformation, good source conditions and favorable petroleum hydrocarbon migration and accumulation features in Altun foothill belt. The main targets for further explorat ion would be Hongliuquan-Qigequan structural-lithologic zones, Shibei-Ganchaigou struc-tural-lithologic zones, Yueyashan fan delta of Palaeogene and stratigraphic unconformity of Neogene in this belt.

Key words: Qaidam basin, Altun foothill belt, fan delta, stratigraphic unoonfority, strike-slipfault zone
