早白垩世晚期，盆地以台地相碳酸盐岩沉积为主，裂谷带附近以发育台地边缘礁滩相沉积；裂谷带两侧的日松革吉它日错分区主要由开阔台地相灰岩组成；盆地南北部的措勤申扎分区和木嘎岗日分区由局限台地相灰岩和陆源进积碎屑岩组成。 - The coqen basin in xizang lies between the bangong - nujiang suture zone and yarlung zangbo suture zone , and once extended northwards and southwards , respectively centred by the qiekan - goicang - asog rift zone as the center of deposition and subsidence during the middle jurassic to the early creatceous . ( 1 ) during the middle - late jurassic , the rift zone was occupied by deep - water turbidites , radiolarian siliceous rocks , shallow - water carbonate rocks , clastic rocks and basic - ultrabasic rocks , while both sides of it by littoral and shallow marine elastic rocks and carbonate rocks
摘要位于班公湖怒江缝合带与雅鲁藏布江缝合带之间的措勤盆地，在中侏罗世早白垩世期间具有以且坎古昌阿索裂谷带为沉积、沉降中心向南北两侧展开的古地理格局：中晚侏罗世时期，裂谷带内由深水浊积岩、放射虫硅质岩和浅水碳酸盐岩、碎屑岩岩片及基性超基性岩等组成；裂谷带两侧由滨浅海相碎屑岩和碳酸盐岩组成。 - Xikuangshan type copper ore deposit named those fe - cu deposits hosted in yinmin formation , kunyang group , which located in kunyang rift valley and the edge of southwest yangzi platform . the best example is xikuangshan allotment , luoxue ore area , dongchuan , yunnan . the type deposit spread in south kunyang rift valley , include dongchuan , wuding - luoci , yuanjiang , yimen , huashengping , hongmenchang and so on
稀矿山式铜矿是指赋存在昆阳群因民组地层中的铜铁矿床，其大地构造背景属于元古代裂谷带，大陆裂谷是超大型铜等多金属矿形成和分布的有利环境，在裂谷下部常发育异常地幔和岩浆源，裂谷空间上的多层次性使矿床具有明显垂向分带特征，其演化时间的长期性、脉动性和继承性便于多期成矿作用相互叠加、矿质的高度聚集。
