古特提斯东昆仑活动陆缘及其区域成矿

ACTIVE CONTINENTAL MARGIN AND REGIONALMETALLOGENESIS OF THE PALAEO-TETHYSIN THE EAST KUNLUN MOUNTAINS

东昆仑地质构造特征、石炭—三叠系火山 -沉积建造及区域岩浆作用研究显示 ,海西 -印支期 ,该区属于古特提斯北侧活动陆缘的组成部分。活动陆缘区特殊的沉积环境、区域岩浆活动及构造变形动力等作用 ,构成了区域矿产形成的主要背景和控制因素 ,从而使不同类型和元素组成的矿床得以形成 ,并表现区域成矿的总体分带规律。

The study on the structure, volcanic sediment and magmatism shows that the east Kunlun Mountains belong to the Palaeo-Tethys active continental margin during the Hercynian-Indosinian period. In this tectonic setting, the special sedimentary environment and regional magmatism as well as tectonic force are the main factors which control the regional metallogenesis.It is the effective factors that lead to the deposits forming in the area, and showing a regular distribution both of ore types and the composition of elements.
