Metallogenic Geological Characteristics and Metallogenic Model of Xiachen-Wangchangmu Fluorite Mine in Tiantai Basin, Zhejiang Province, China

Abstract:

Based on the field geological survey and the previous correlational studies, remote sensing interpretation and field geological survey methods are combined and used in this study. The mineral field geological characteristics, ore body geological characteristics, wall-rock alternation and metallogenic model were analysized and summarized in the XiaChen-WangChangMu fluorite mine in TianTai basin, which is a cretaceous inherited-transition basin that has the advantageous environment riched in fluorite. The main ore-bodies are lenticular or vein-like, and the general strike of ore-body is NW trending, while the dip slip is NE or SW, lateral plunging direction mainly from northwest to southeast. The supposed ore forming process in this area is as follows: atmosphere precipitation seeps into the fracture and pores in the rock. Heated by geothermy or other heat sources, the fluoride were leached out continuously; the ore-forming fluids rise along the ore-controlling fracture during the metallogenic stage as the environment change. SiO2 is the first mineral to be precipitated, then the fluids turn from acid into weak acid, and the fluorite begins to crystallize and form the main ore body, with carbonation symbolizing the end of the mineralization.
