According to magnetic analysis of 302 rock samples from 25 sampling points of Fenghuagshan rock body in Tongling area, Anhui Province, the magnetic fabrics obtaned in the study area can represent flow magnetic fabrics during magmatic emplacement, because they were not considerably influenced by tectonic activity after the formation of magma; the process of magmatic emplacement was a quasi-static process, in which the mobility of magma was rather weak, and the differentiation and assimilation-hybridization were quite strong; the early stage of magmatic emplacement might have been controlled by the NNE-trending maximum principal compressional shear, whereas the late stage was probably conditioned by the southwest maximum principal compressional shear; the southwest part of Fenghuangshan rock body where the Yaoyuanshan ore deposit is located is the hanging wall of the rock body, whereas the northeast part where the Xianrenchong ore deposit is situated is the lying wall of the rock body, suggesting that Fenghuangshan rock body pitches southwestward; in areas adjacent to the southwest part of Fenghuangshan rock body (such as in Lailong Mountain) there might exist small stocks formed in the same period as the emplacement of Fenghuangshan rock body, which are promising areas for ore prospecting.
