摘要
红牛铜矿位于云南省香格里拉市格咱乡,属于德格-乡城铜铅锌银多金属成矿带,是格咱岛弧带内燕山晚期成矿系统最大的矽卡岩型铜多金属矿床。通过对矿区找矿突破勘查思路、勘查方法及勘查效果进行研究,将矿区找矿突破划分为从无到有“零”突破、从少到多“量”突破、从小到大“新”突破三个阶段,从地质-地球物理-地球化学-矿产四个方面总结了勘查选区、核心区勘查、深边部勘查三个层面的勘查思路,集成了勘查选区、中浅部勘查、深部勘查三套勘查技术方法,并从地质-地球物理-地球化学三个方面总结了矿区勘查标志,为格咱岛弧带内在新一轮找矿战略行动中寻找类似矿床提供勘查思路、勘查技术方法及勘查标志示范参考,为发展资源经济、保障国家资源安全做出新的贡献。
The Hongniu Copper Mine is situated in Geza Township,Shangri-La City,Northwest Yunnan Province,and is part of the Dege-Xiangcheng copper-lead-zinc-silver polymetallic mineralization belt.It represents the largest skarn-type copper polymetallic deposit in the Yanshanian late mineralization system of the Geza Island Arc Zone.By studying the ore exploration breakthroughs,methods,and effects in the mine area,the ore exploration breakthrough process is categorized into three stages:the initial'zero'breakthrough(from nothing),the subsequent'quantity'breakthrough from less to more,and the recent'new'breakthrough(from small to large).The exploration strategies are summarized for selection area targeting,core area exploration,and deep/edge exploration,integrating geology,geophysics,geochemistry,and mineral resources assessment.Exploration methods for exploration selection,middle-shallow exploration,and deep exploration are integrated,while exploration markers for the mine area are summarized from geological,geophysical,and geochemical perspectives.This study presents exploration concepts,integrated technical methods,and exploration markers for identifying similar deposits in the Geza Island Arc Zone during the next round of mineral exploration,thereby contributing to regional resource economic development and national resource security.
