Abstract The new progresses and achievements of 1∶50 000 regional geological survey of Wuyinhurile Temple sheet and the other three sheets in Inner Mongolia were as follows. Based on rock associations, animal and plant fossils and isotopic age, the authors redefined and divided the rock succession into sixteen lithostratigraphic mapping units. Abundant animal and plant fossils were found for the first time in a variety of sedimentary rock intervals, and the chronological frameworks of the sedimentary strata were established. The intrusive rocks were redivided into four mapping units, and the chronological frameworks of intrusive rocks were established. A large-scale ductile deformation zone was discovered and interpreted as an inverse-left-lateral ductile strike-slip fault of the late Middle Triassic period, which was the southern part of the NE-trending Ergun River-Alongshan ductile deformation domain. The authors have discovered twenty new mineral occurrences, including three metal mineral occurrences, six mineralization occurrences, nine non-metallic occurrences, and two mineralization occurrences. This paper also summarized the metallogenic regularity in the area, and delineated mineralization and prospecting target areas.

Key words： strata fossil Chaihe Formation intrusive rock mineral occurrence ductile deformation zone
