来宾地区中晚二叠世之交烃源岩沉积的主控因素及大地构造背景
Main factors controlling the deposition of the Middle-Upper Permian source rocks in Laibin area and its tectonic setting
摘要
Abstract
Based on analyzing geochemical indicators, such as total organic concentration ( TOC ) , paleoproductivity ( Ba/Al ratio), and paleoredox ( V/Cr, V/(V + Ni)), of the Maokou Formation (the Middle Permian) and the Heshan Fromation (the Upper Permian) from the Penglaitan section and Tieqiao section in Laibin area , it is concluded that ( 1 ) good source rocks ( average TOC == 3 % ) locally developed at the Penglaitan section and (2 ) the basin environment with anoxic depositional condition mainly controlled the accumulation of them. Compared with regional study, we consider that source rocks not developed regionally in the Qiangui basin during the Late Permian, which was probably related to the regional uplift caused by the Emeishan Plume.关键词
