本文重点讨论了四川重庆北碚天府地区上二叠统生物礁的岩石类型,生物礁组合的微相特征和发育演化史。微相组合和生物学特征证明文星场生物礁是发育在开放性泻湖中的点礁,它的生长、发育受沉积速率控制,消亡的原因是由于海平面的上升速度超过礁的生长速度。 This article focuses on the rock types of the Upper Permian reefs in Beibei area in Beibei, Sichuan, and the microfacies characteristics and developmental history of reef assemblages. Micro-phase assemblage and biological characteristics prove that Wenxuechang reef is a reef developing in an open lagoon. Its growth and development are controlled and controlled by the sedimentation rate. The reason is that sea-level rise rate exceeds the reef growth rate.
