摘　　要：宁夏中卫市矿床地质特征分布具有层次性,结合地球化学特征及矿化线索,分析宁夏中卫市矿床地质特征与矿化阶段,宁夏中卫市矿床研究区及邻区处于奥陶—白垩纪地层,Cu-Ni-Cr等相关组合异常,其相匹配的枕状玄武岩的分布较为广阔。结合图模型分析方法,通过二乘回归分析方法,实现对宁夏中卫市矿床勘查及找矿过程中矿床特征分析以及测量,根据赋矿岩性的差异性,分析岩体、地层以及构造等因素对成矿特征的影响,实现矿床地质特征与矿化阶段划分,并通过数据分析方法进行矿床规模及成矿分布的数据处理分析。The distribution of geological characteristics of deposits in Zhongwei City,Ningxia is hierarchical.Combined with geochemical characteristics and mineralization clues,the geological characteristics and mineralization stage of deposits in Zhongwei City,Ningxia are analyzed.The study area and adjacent areas of deposits in Zhongwei City,Ningxia are located in Ordovician Cretaceous strata,Cu Ni Cr and other related combination anomalies and the matching pillow basalt is widely distributed.Combined with the graph model analysis method,through the method of binary regression analysis,to realize the analysis and measurement of the characteristics of the zhongwei deposit in Ningxia province in the process of exploration and prospecting,according to the difference of hosting lithology,analysis of the influence of rock mass,stratum and structure and other factors on the characteristics of mineralization,realize the division of the geological characteristics of the deposit and mineralization stage.The data processing and analysis of deposit size and mineralization distribution are carried out by data analysis method.
