摘　　要：山上里金矿位于胶东半岛环太平洋构造带,受区域构造及火山期后热液共同影响,经早期蚀变作用和晚期多次叠加矿化,形成了该矿床。通过研究,圈定3条矿脉,矿体6个,其中Ⅰ-①、Ⅱ-①矿体为矿区主矿体,推算金金属资源量约占整个矿山的87%,其余矿体规模较小,探求(332+333)类金金属量7016 kg,查明矿床为中型金矿床;通过分析区域地质构造特征、物化探异常特征、矿体地质特征,总结成岩成矿环境因素,认为矿床类型为中低温热液充填交代蚀变岩型金矿床。The Shanshangli Gold Deposit is located in the Pacific Rim tectonic belt of the Jiaodong Peninsula.Under the combined influence of regional structures and post-volcanic hydrothermal fluids,the deposit was formed through early alteration and multiple superimposed mineralization in the later period.Through research,3 ore veins and 6 ore bodies are delineated,of whichⅠ-①andⅡ-①ore bodies were the main ore bodies in the mining area.It was estimated that the gold metal resources account for about 87%of the entire mine.The remaining ore bodies were small in scale.The amount of(332+333)gold-like metals was 7016 kg,and the deposit was identified as a medium-sized gold deposit.By analyzing the regional geological structure characteristics,physical and geochemical anomaly characteristics,and ore body geological characteristics,the diagenetic and metallogenic environmental factors were summarized,the type of deposit was considered to be a metasomatism-altered rock type gold deposit filled with medium and low temperature hydrothermal fluids.
