会理—东川坳拉槽对铜多金属成矿的控制

HUILI-DONGCHUAN AULACOGEN CONTROLLING ON THE MINERALIZA-TION OF COPPER-POLYMETALLIC ORE DEPOSITS

本文在论述会理—东川坳拉槽的地质构造特征和主要铜矿床类型的基础上，着重指出坳拉槽火山活动、生长断裂、次级局限盆地、富铜地幔及坳拉槽构造演化阶段与坳拉槽沿走向地壳类型变化是控制铜多金属成矿的主要构造因素。

Based on the description of geological and tectonic features and main copper deposit types of the Huli-Dongchuan Aulacogen,this paper emphatically points out that volcanic activities,contemporaneous faults,secondary confined basins in the aulacogen,copper-rich mantle,evolutionary stages of the aulcacogen and variation in earth crust along the aulacogen are the main copper-polymetallic ore controls
