SEDIMENTARY FACIES AND TECTONIC EVOLUTION IN THE TONGZIYAN FORMATION OF THE LOWER PERMIAN IN THE SOUTHWEST OF FUJIAN PROVINCE

摘要: 闽西南地区二叠系童子岩组可划分为3段,政和—大埔断裂带以西,南平—宁化构造岩浆带以南地区,分连城型、龙岩型和天湖山型3种沉积类型,主要为一套海陆交互相含煤碎屑岩沉积,一般厚700~800 m,从东往西、从南到北逐渐变薄。二叠系童子岩组沉积盆地在经历了印支—燕山期多期次的构造变动、岩浆作用、风化剥蚀等改造后,部分保存下来;其中影响最大的是印支期,其次是燕山早期。Abstract: The Permian Tongziyan Formation in the southwest of Fujian Province can be divided into 3 members.There are 3 types of sedimentary facies:Liancheng,Longyan and Tianhushan.This formation is generally composed of coal-bearing clastic rock sediments of marine and continental facies,700-800 m thick,reducing from east,south to west,north.Having experienced tectonic evolution,magmatism and weathering degradation in the Indosinian and Yanshan epochs,part of the sedimentary basin of the Permian Tongziyan Formation is preserved.The Indosinian epoch has the largest influence,and the Yanshan epoch the second.
