Abstract
Based on a systematic review of the evolution from macroscopic qualitative description to high-precision quantitative analysis of the Permian lithofacies palaeogeography in southern China,this study focuses on the rock evolution characteristics and formation mechanisms centered on the dolomite of the Qixia Formation-Maokou Formation and the siliceous rocks of the Gufeng Formation、Dalong Formation.The study emphasizes that the spatiotemporal distribution of lithofacies profoundly reflects the control of tectonics,especially the dynamic background driven by scissor-like collision and the distal effect of mantle plumes,which determine the spatiotemporal evolution of the sedimentary pattern and the characteristics of the platform-basin differentiation.In response to the current bottleneck problem in the delimitation of facies belts,this study proposes that the spatiotemporal constraints should be strengthened by relying on palaeobiogeographic similarity indicators,and combined with big data and artificial intelligence technologies,to promote the transformation from static map drawing to dynamic process prediction,aiming to provide more rigorous petrological evidence and evolution models for the evaluation of"sweet spots"in unconventional oil and gas exploration.关键词
