Yimen Fengshan copper deposit is a typical example of Yimen-type copper deposit which is located in the copper mineralized zone of Kunyang rift valley, Yunnan Province, China. The deposit is evidently controlled by diapir and structure, and ore bodys are located in cataclastic dolomite of Lüzhijiang Formation Fengshan member. Diapir structure is a special structural feature with the old tectonic massif pierced in the new formation. Research about the relationship of diapir, ore body and structure of controlling them has important theoretical value and prospecting significance. Structures control the distribution of diapir which provides the mineralization. Structure and diapir are the main ore-controlling which control the distribution of ore bodies. By researching Fengshan ore bodies, diapir of controlling ore bodies and construction features, we discovered that diapir and constructure have the tendency of W-SW, and diapir has the feature of S-SW side of V. By controlling of the two features, ore bodies with the S-SW side of the V characteristics, the characteristics provide an important basis for the ormation mechanism of diaper and the deep ore-finding prognosis.
