| 摘 要： | 白乃庙地区绿色片岩主要为阳起石＋钙质斜长石组合，形成不同矿物组合和亚带。白乃庙地区花岗质侵入岩体侵入到岛弧蛇绿岩中形成外接触变质带内—阳起石～钙质斜长石带。该带的确立为建立阳起石～钙质斜长石角门岩相及分布其中的接触变质型铜钼矿床提供依据。

| Abstract: | The green shist mainly are actinolite+calcolagioclase assemblage that formed of different minerals assemblage and subzone. The granitic instrusive rock body intruded into the island are ophiolite where formed of tie actinolie-calcplagioclase zone of inner outer contact metamorphic zone. The zone of establish offered the for that the actinolite calcplagioclase hornfels face in which distributed the contact metamophic type of copper molybdnum deposit in Bainairnao area. |
