Abstract:
The mining area is located in the Cu-Pb-Zn-Ag fluorite metallogenic subzone in the northern Wuyishan metallogenic belt,which has superior fluorite metallogenic conditions. This paper combines the working methods such as geological survey, trenching engineering and drilling engineering,summarizes the spatial distribution, occurrence state and ore-controlling factors of orebody according to the existing tunnel engineering, and carries out the research on metallogenic regularities and mineralization. Through the comprehensive study of the orebody and the metallogenic structure, the metallogenic age is judged and the metallogenic mechanism is discussed. It shows a medium-low temperature hydrothermal filling type fluorite deposit in the area, whose ore-forming material is derived from late Indosinian porphyritic biotite granite. The NE-trending main fault and secondary compression-torsional fault are the main ore-conducting and ore-storage structure in mining area. The study proves that the resource reserves of this fluorite deposit has reached the medium scale, which expands the resource prospects of the mining area, and points out the direction of prospecting.
