A belt of intermediate to acidic intrusive rocks occurs in western Fengqing, Yunnan Province, Occurring in stripe and zonal shapes, and in NNE sapce distribution, and it is eroded by monzonitic granite in Trias, featuring as batholith relies of irregular stripe and zonal shapes.Some researchers have considered that this rock is part of Lincang granite (Xinglin Li , 1996) and the zircon U-Pb age was 288Ma, formed in the Permian, belonged to the products of tectono-magmatic activation in the late Hercynian. On the basis of previous studies, this paper had a preliminary analysis of its genesis from the geological features, petrographic, mineral chemical.
