Xinzhuang gold deposit in Shanxi province is located in the Northern Margin of North China Platform and the Hengshan mountain of Northeast Shanxi, which is typical vein hydrothermal gold deposit.The deposit geological features, the ore-forming geological conditions and the deposits genesis of Xinzhuang gold deposit were studied according to the genesis and prognosis theory and method of gold deposits. The location metallogenic regularity and typical recognition of vein of Xinzhuang gold deposit were analyzed. Prospecting targets were predicted on the base of tectononic geochemistry anomaly analysis.The main details in this paper are as follows:The classifying of metallogenesis types, the theory and method of the metallogenesis were summarized in the domestic and overseas situation of study.The deposit geological features were studied, geological features of vein-1 were dissected mainly. Orebody feature was studied from location, shape, occurrence, scale, and variation of grade of orebody, texture and structure of ores, wall rock alteration, ore-forming stages aspect.The ore-forming geological conditions were probed from the relationship between mineralization and stratum, structure, magma rock aspect. The gneiss stratum of high gold content in Wutai group greenstone belt is the source bed; The orebody was controlled by the structure which is the most important factor in mineralization; The magmatic rock of Yanshanian is the beneficial parent rock of mineralizing.The occurrence regularity of orebody and main sign of recognition of vein of Xinzhuang gold deposit were analyzed on the base of analysis of mineralizing geological conditions.Xin zhuang gold deposits is typical and yanshanian mediosilicic-acid magma intrusion activities related to the low temperature filling quartz vein type gold deposits on the base of comprehensively analyzing of geological characteristics of ore deposit and mineralizing geological conditions.According to tectononic geochemistry survey in Xinzhuang area and mathematical statistic analysis of data, the best ore-forming indicator elements is Cu, the optimal indicator elements combination are Au-Cu-Ag-Pb-Zn.6 Prime tectononic geochemistry anomalous belts were delimitated according to index of lgAuCuAgPbZn.The beneficial ore-prospecting information on geology, geochemistry and geophysics were summarized.8 prospecting targets positions were determined combining investigation and collection of the beneficial ore-prospecting information in survey area. The importance of prospecting targets was sequenced.
