Early Paleozoic Extension-Compression Transition and Formation of a Paleo-Oil Reservoir System in the NW Sichuan Basin: Implications for Deeply Buried Hydrocarbon Accumulation

<div>Surface geological characteristics and paleo-oil reservoir distribution in the TJS PU area. The Tianjingshan Paleouplift can be divided into south, middle, and north segment. Nowadays, the Tianjingshan structure belt (Tianjingshan Paleouplift area) is overlapping on the Mianyang-Changning Intracaratonic Sag.</div>
