摘　　要：针对中等尺度范围(或中等比例尺)区域成矿潜力和已知矿山的深部及外围资源评价等问题,试图用成矿地质事件方法开展相关研究。成矿地质事件评价方法,就是在恢复矿床形成过程并建立成矿模式的基础上,通过对矿源岩系的构造变形岩相形迹追索来恢复与成矿有重要意义的地质事件及其演化过程,研究在这一系列地质事件中成矿物质的分布规律和逐步富集成矿的标志及程度,并用以进一步探索、指导区域资源潜力评价和填图找矿的方法。应用这一思路对南岭中段锡多金属矿和胶东矿集区金矿进行了区域成矿地质事件研究和地质填(编)图方法的初步探讨。This paper attempts to use the ore-forming geological event method to study the problems regarding the evaluation of medium-scale regional ore potentials and mineral resources at depths and peripheries of the known mines. This method can be briefly summarized as follows: based on the reconstruction of the process of formation of related ore deposits and construction of metallogenic models, reconstruct some important ore-forming geological events and their evolution processes are reconstructed by tracing the tectono-deformation petrofacies in the ore sources series, study the distribution patterns of ore materials in a series of geological events and indicators and degrees of gradual ore material concentration and formation of ore deposits and further explore and direct evaluation of regional resource potentials, mapping and mineral exploration in ore deposit concentration areas. With this idea in mind, the authors studied the regional ore-forming geological events and geological mapping method in tin-polymetallic deposits in the central segment of the Nanling Mountains, South China, and the Jiaodong gold deposit concentration area, Shandong province.
