Abstract

Abstract

Zhao-Ping fault belt is an important gold metallogenic belt in Jiaodong area, and lots of altered-rock-types and quartz-vein-type gold deposits output in the belt and secondary faults of the footwall. To explore the geochemical features of the wall rock alteration, the Potouqing fault in Zhao-ping fault belt is taken as the research object, with the profile measuring and sample analyzing. It's showed that the alteration zones of the Potouqing fault are evident in Zhaoping fault belt. With the different alteration intensities in altered rock, the major elements' migration regularity is obvious. The enrichment of HREE is showed in the REE distribution curve. Eu and Ce have obviously negative anomaly. With the process from weak alteration to strong alteration, theΣREE, LREE and HREE significantly decrease, and the regular changes are showed by the corresponding characteristic value, Au-Ag-Bi-Co-Cu-Mo-Ni-Pb-Zn is the indicator element suite which is closely related to the gold mineralization.
