摘要
通过龙门山南段宝兴至荥经地区区域地质、铅锌矿化特征的研究，划分矿化类型，着重分析区域成矿地质条件，提出“层─盆─破─热”是本区层控型铅锌矿形成的基本因素。总结出铅锌矿在本区形成时间有“三个高峰期”，空间集中于“一带两弧”的时空分布规律。在分析不同矿化类型成矿模式的基础上，建立了区域综合理想成矿模式，为本区找矿靶区和预测区的确定奠定了坚实基础。
The types of lead and zinc mineralization in the area of Baoxing-Yingjing are classi- fied after the study of the regional geology and mineralization characteristics.Emphasis is put on the analysis of the regional geological conditions of mineralization. Layer,basin,facture and heat are the fundamental factors controlling the formation of stratabound lead and zinc ore dcposits in the area. The time and spatial regulation of three stages of lead and zin mineraliZation clima and of the concentration of ore deposits in one belt and two arcs is proposed and summarized.Bsaed on the discription of various minerogenetic models,the regional comprehensive ideal model of mineral genesis is established.The model lays a foundation for the determination of ore-predict- ing and ore-hunting areas.
