摘    要：麻阳铜矿是一种地洼型砂岩铜矿,矿体受山间型河流古河道控制,其长轴与地层走向近于直交。由于地洼盆地属活动区型盆地,差异升降运动频繁,致使河道来回摆动,矿体也随之侧列产出。本文分析了成矿的大地构造环境及其决定的古地理条件,认识了矿体的分布规律,纠正了以往的找矿思路,指出了找矿方向。

Abstract: Mayang Copper Deposit belongs to Diwa Basin sandstone type copper deposit.Its ore-bearing strata is net river deposit in delta and its ore bodies are distri-buted within the paleo-netriver. The stretching direction of the ore bodies iscontrolled by the paleoriver system, the circulating direction, of undergroundwater and the structural stress of metallogenic epoch. Through analysingthe geotectonic condition and the essential paleography, the distributionregularity of the ore bodies has been. known, and the former prospecting ideahas been improved. Based on this the way of prospecting has been presented.
