四川会理—会东地区火山沉积变质型铜矿遥感地质特征及找矿标志

Remote-sensing Geological Features and Prospecting Criteria for Volcano-Sedimentary Metamorphic Cu Deposits in the Huili-Huidong Region, Sichuan

通过遥感地质构造特征解译,结合地质分析,对两会地区火山—沉积变质型铜矿的成矿条件,矿床地质特征及控矿因素进行了研究,将矿床类型细分为火山沉积变质型(拉拉式)、沉积变质型(大箐式,相当于东川式)、火山沉积热液改造型(小青山式)三种亚型,分别提出了各亚型铜矿的遥感找矿标志。

This paper deals with ore-forming conditions, geological features and ore-control factors of the volcano-sedimentary metamorphic Cu deposits in the Huili-Huidong region by means of remote-sensing geological features. These Cu deposits may be divided into volcano-sedimentary metamorphic type （Lala type）, sedimentary-metamorphic type （Daqing type or Dongchaun type） and volcano-sedimentary-reformed type （Xiaoqingshan type）. Their prospecting criteria are put forward.
