Abstract:
Based on the strdy of stratigraphy and quantitative Sedimentology of each frndamental section,according to the "Single Factor Anlysis and Comprehensive Mapping Method",various single factor maps and quantiative lithofacies palaeogeography maps of the Feixianguan Aga (Indian),Jianlingjiang Age(Olenikian),Leikoupo Age (Anisian)and Tianjingshan Age(Ladian) of the Early and Middle Trassic of south china were studied and mapped,In these lithofacies palaeogeography maps,the determination of the first rank,second rank and third rank paleogeographical units was based on quantiative single factror data,The framework of the lithofacies paleogeography of each age can be generalized as follows:lands altemated with seas,platforms altenatedwith basins,in platforms there were basins,in basins therewere platforms,in platforms there werebanks and flats,and there were slopes between pltforms and development Fron the Feixianguan Age of the Earlyu Triassic to the Tianjingshan Age of the Middle Trassic is a relatively large regssion process,Such quantitative study and mapping of lithofacies palaeogeography provid the most fundamental scientific grounds for the exploration of oil and gas in the Lower and Middle Triassic of South China.
