昆嵛山岩体东缘金矿成矿规律研究及找矿靶区划分

昆嵛山岩体是多期次的复式杂岩体，位于胶东半岛米山断裂和牟平断裂之间，是华北克拉通和苏鲁超高压变质带的过渡带。区域金矿成矿类型主要为与中生代燕山期花岗岩有关的岩浆热液型。对昆嵛山岩体东缘物探、化探、遥感、自然重砂信息提取，分析了金矿（点）床检查成果充分分析研究，划分出下卧龙、吴格庄和万家口等3个金矿重点工作区。经过对重点工作区内金矿成矿规律研究，确定区内金矿多与细粒花岗岩和玲珑序列花岗岩相关。建立了昆嵛山地区金矿综合找矿模型，按照“定位+定边”的方法，圈定了下卧龙靶区等9个找矿靶区。

Study on Metallogenic Regularity of Gold Deposits in Kunyushan Rock and Division of Prospecting Target Areas

The Kunyushan rock is a multistage complex. It is located between Mishan fault and Muping fault in Jiaodong Peninsula. It is a transitional zone between the north China Craton and Sulu UHP metamorphic belt. The types of regional gold mineralization are magmatic hydrothermal type related to Mesozoic Yanshan period granite. Based on analysis and study of geophysical prospecting, geochemical exploration, remote sensing, natural heavy sand information extraction and gold deposit (spot) bed inspection results in the eastern margin of Kunyushan rock mass, three key working areas of gold deposits, such as Xiawulong, Wugezhuang and Wanjiakou have been divided. Based on the study of metallogenic regularity of gold deposits in the key working areas, it is confirmed that gold deposits in the area are mostly related to finegrained granites and Linglong sequence granite. Comprehensive prospecting model of gold deposits in Kunyushan area has been established, and nine prospecting target areas have been circled.
