Abstract:

It is a great challenge to us to apply the plate tectonic theory to the East Asia Paleocontinent which has very complicated tectonic framework and geological evolution history. Prof. WANG Hongzhen proposed the tectonic domain concept as the first order tectonic unit in continent, and proposed the convergent lithosphere consumption zones as a boundary between the tectonic domains, and based upon the concepts a new tectonic and oilbearing basins map had been constructed. The main large superimposed basins (Tarim, Sichuan, Ordos, etc.) were all developed in the stable center area of the stable Precombrain basement. The relative stable condition may have been a very important condition for oil and gas accumulation. The multistage tectonic movement controlled the basin evolution history and could be correlated with the interaction of geological events between the domains.

Key words: tectonic domain, superimposed basin, oil and gas accumulation
