Abstract

Abstract

The research on structure and mineralization alteration of Q240 vein in Xiaoqinling gold deposit indicates that the vein undergoes multi-stage tectonic activity transformation. In the early stage, structural belt undergone mainly left-lateral brittle ductile shear deformation, and developed NW-trending quartz vein with the structure lineation plunging toward SW. Mineralization of the vein was characterized by the rich pyrite with a strip distribution. While the later right-lateral brittle ductile shear deformation formed the NEE-trending pyrite quartz vein. By analyzing the change characteristics of three orebodies in the plane, we know that the vein is constructed by multi-superimposed tectonic hydrothermal activity and the main structure is associated with the left-lateral shear deformation, and later suffered the right-lateral deformation. The NEE-trending structure plane forms a space for mineralization. Combined with stress environment, ore control regularity and orebody lateral characteristics, we get that the ore body appear equidistant regularity in the strike and dip based on the structure alteration. According to the research, we predict three mineralization targets in the deep of Q240 vein.
- Xiaoqinling gold field /
- fault structure /
- the Q240 vein /
- deep prognostication
