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