| Abstract: | This paper (1) describes the strata, structures and magmatic rocks occurring in Shanyang area, (2) summarizes the characteristics of the spatial distribution, rock types, dominant minerals, petrochemical composition, rock alkalinity, rear earth elements and microelements of the small rock bodies in this area, (3) provides the evidence to indicate the crustal mantle syntectic genesis of the acid intermediate acid small rock bodies, in view of five aspects, (4) analyses the polymetallic mineralization, which is dominant in the rock bodies, in Xiaohekou area of Shanyang county, and (5) develops a metallogenetic model. |
