Development process of fault structure and formation and evolution of ore-controlling structure: A case study of the Zoujiashan uranium deposit
CHEN Bailin
2020, 26(3): 285-298. doi: 10.12090/j.issn.1006-6616.2020.26.03.027

Abstract:
Hydrothermal lode deposit is mainly controlled by fault structure. The ore-bearing or ore-hosting structures controlling the emplacement of ore-body and ore vein are often minor second-order faults or fractures,while the major faults are generally considered as passage-ways for ore fluids; however,t...

Abstract:
The NW-trending faults in the Youjiang area originated from synsedimentary faults developed in the Youjiang Basin of Late Paleozoic. In Cenozoic these equidistantly spaced faults have undergone multiple left-lateral strike-slip activities,which then led to a simple-shear deformation of the Youjiang ...
