摘　　要：鄂尔多斯地区包含鄂尔多斯西缘和鄂尔多斯盆地2个三级成矿单元。笔者对鄂尔多斯西缘成矿带厘定矿床成矿系列12个,解析亚系列19个;鄂尔多斯盆地成矿区厘定矿床成矿系列8个,解析亚系列14个。以矿床成矿系列为基础建立了整个鄂尔多斯地区成矿谱系;以矿床成矿亚系列为基础分别细化了鄂尔多斯西缘成矿谱系和鄂尔多斯盆地成矿谱系;按前寒武纪—早古生代—晚古生代—中新生代地质进程,概述了区域成矿演化史,并例举了大量沉积作用、岩浆作用、变质作用、流体作用和表生作用相关矿床实例,使读者既可了解区域成矿总体格架,也可查询所关注的具体矿床。Ordos area consist of two metallogenic belts:Ordos basin and its western margin.There are 12 metallogenic series and 19 metallogenic subseries of mineral deposits in the metallogenic belt of western margin of Ordos basin,and 8 metallogenic series and 14 metallogenic subseries of mineral deposits in the metallogenic zone of Ordos basin.Based on these metallogenic series of mineral deposits,the metallogenic pedigree of Ordos area was established.According to these metallogenic subseries of mineral deposits,the refined gional metallogenic pedigrees of Ordos basin and its western margin were established.The rule of regional Metallogenic evolution was summarized in sequence from Precambriam,Early Paleozoic,Neopaleozoic,Mesozoic to Cenozoic.In order to help readers not only understand the regional metallogenic evolution history,but also can query concrete deposits which they are interested in,a lot of deposit examples which related to sedimentation,magmatism,metamorphism and supergenesis are enumerated in this article.
