| 中文摘要:本文以我国最重要的大型金矿集中区之一——胶东矿集区为研究对象，对胶东矿集区的地质异常进行了全面研究，把该区地质异常分为三级，即宏观地质异常、中观地质异常和微观地质异常，并对各级异常的特征进行了深入研究。在此基础上利用地理信息系统(GIS)对胶东矿集区金成矿的地质异常控制进行了研究，并对胶东矿集区地质异常致矿、地质异常控矿和地质异常示矿进行了深刻阐述。同时就胶东矿集区的地质异常准则进行了全面总结，地质异常准则包括：区域构造异常准则、区域岩性组合异常准则、区域地球化学异常准则和区域物探异常准则。 |

| Abstract:The Jiaodong gold ore concentration area is one of the largest gold ore concentration areas in China. With this area as a study object, the authors investigated in detail geo-anomalies in this area. The geo-anomalies in Jiaodong gold ore concentration area can be assigned to three levels, namely macroscopic geo-anomalies, medium geo-anomalies, and microcosmic geo-anomalies. Characteristics of geo-anomalies at different levels were also studied. The controlling role of the geo-anomaly in the formation of gold deposits was studied by means of Geographical Information System (GIS). The ore-forming, ore-controlling, and ore-indicating roles of geo-anomalies in Jiaodong gold ore concentration area were also investigated. The criteria of geo-anomalies in Jiaodong gold ore concentration area are summarized, which include the criteria of tectonic anomalies, the criteria of lithologic combination anomalies, the criteria of geochemical anomalies and the criteria of geophysical anomalies. The summarization of the criteria of geo-anomalies is the sublimation in the understanding of ore-forming regularity in Jiaodong gold ore concentration area and can play an important role in ore prognosis. |
