安第斯成矿带斑岩铜矿成矿规律综述

Metallogenic regularities of porphyry copper in the Andes metallogenic belt

本文重点论述了安第斯成矿带地质构造背景、矿床特征及成矿规律,提出了安第斯成矿带受板块俯冲致深成岩浆强烈侵位和近南北的逆冲断层控制矿床的双重构造因素的控制(大多数大型、超大型斑岩铜矿产于该断裂带)及安第斯成矿带斑岩铜矿南北分区,东西分带的矿床分布规律。

This paper mainly discusses geological structure background, features and metallogenic regularity of ore deposit in the Andes metallogenic belt. Put forward the formation of ore deposit is controlled by the dual structure factors：First, Andean metallogenic belt is strongly affected by the plate subduction leads to strong invasion of plutonic magma;Secondly, nearly north-south thrust fault. Most of the large and ultra-large porphyry copper deposits are found in this fault zone. And put forward the distribution law of ore deposit that the porphyry copper in the Andes metallogenic belt is regionalized from south to north and zoning from east to west.
