摘要
据地质构造、沉积学、岩石化学和地球化学等方面资料, 洱源地区三叠系双峰式火山岩属川西甘孜-理塘带的南延部分, 处于“剪刀式”扩张的末端, 具有洋盆—大陆裂谷的过渡性质, 更接近于大陆 (边缘) 裂谷。
According to the information of geological structure, sedimentology, petrochemistry and geochemistry, we think the triassic two-peak type volcanic rocks in Eryuan area belong to the southwards extensive part of the Ganzi-Litang zone of west Sichuan and is at the end of “scissors type” expansion, with transitional characteristics between ocean basin and land rift, near the later.
