中文摘要:
      土状铜矿普遍发育于滇中地区中元古界昆阳群落雪组和绿汁江组的土状风化壳内。是一种新的矿床类型,也是昆阳群中铜矿床的富矿,过去认为是不可利用资源,20世纪90年代后期随着湿法冶金技术的进步,使之成为可用资源。其形成演化与特殊的成矿背景有密不可分的关系。
英文摘要:
      Earthy copper deposits exist pervasively in the earthy weathering curst on the surface of Mesoproterozoic Luoxie Formation and Luzhijiang Formation. They are regarded as a new type of copper mineral resources and one of rich copper deposits in Kunyang Group now. However, they have been regarded as an unworthy copper mineral resources for a long time. Since in the late 1990s, with new hydrometallurgical technology advance, made these deposits become one of the effective mineral resources. Formation and evolvement of these earthy copper deposits are associated with a particular geologic setting of metallogenesis.
