从宏观基础地质入手，按矿床学的一些基本概念，针对东川-易门铜矿床地质地球化学特征，探讨了一些存在争议的重要问题。研究认为：狮山段是绿汁江组下部独立存在的地层层位；东川-易门式铜矿床属沉积-改造成因，其中的层状铜矿属沉积成岩成因，不是“热液成矿”；所谓东川-易门式矿床(稀矿山除外)为“喷流沉积成矿”或“岩浆叠加”，尚依据不足；刺穿体是构造作用产物，对成矿有利，是良好的找矿标志，其中的角砾岩主要是沉积角砾岩与构造角砾岩，或沉积-构造角砾岩，不足以冠名“隐爆角砾岩(筒)”。

On the basis of the geological and geochemical characteristics of Dongchuan-Yimen type copper deposits, the important issues regarding the metallogeny of this type of copper deposit are discussed. The authors suggest that the Shishan Member exists independently and belongs to the lower part of the Luzhijiang Formation. The Dongchuan-Yimen type copper deposits are sedimentary-reworked origin, and the stratiform deposits are sedimentary-diagenetic rather than hydrothermal origin. No direct evidence to propose that the existance of exhalative sedimentary mineralization and superimposed mineralization in this area. The piercing bodies formed by structure is important prospecting criteria. In the piercing bodies, there are sedimentary breccias and structure breccias instead of crypto-explosion breccias (pipe).
