摘要
The Baiyangping ore district is located in northren Lanping Mesozonic-Cenozoic foreland basin, Yunnan Province. A front fault of the nappe system related to the Jinshajian orogenic belt is the most important ore-controlling structure in the ore district, and there is a series of Pb-Zn-Ag-Cu polymetallic ore bodies along the Huachangshan fault zone. There exists a corresponding relationship between the distribution of ore-forming elements and the zoning of the tectonite. The deformation of the fault was brittle and formed the cataclastic tectonites. There exists the regular variation of the rock texture, the boundary configuration of the calcite particle and the grain size. The C-T illustration of the calcite shows that the primary movement direction of the nappe is from SE to NW.
