摘　　要：木里新山在地质构造上处于扬子地台西缘推覆弧形构造带上的一个穹窿中,地表出露有许多褐铁矿体,规模很大。本文认为这些铁帽由原生铜矿床氧化形成,且与李伍铜矿具有相同的成矿地质环境和类似的矿床地质特征,预测铁帽的下部,可能存在一中至大型的原生铜矿床。Xinshan gossan in Muli, tectonically, lies in a dome of the arc-nappe structural zone in the western margin of the Yangtze Platform. Many limonite orebodies have been ex-posed. The Present paper suggests that the Xinshan gossan was formed by oxidation from the primary copper deposit which is of geological setting and geological feature similar to those of Liwu copper deposit, and, therefore, predicts that a large- or medium-scale pri-mary copper deposit is buried under the gossan.
