丰村铅锌矿位于钦杭成矿带西南段,廉江-信宜上古生界褶皱系内(周永章等,2012)。野外地质观察显示,该铅锌矿由径口、山背、下园垌及大博面等四个矿段组成。其中以径口矿段规模大,矿化较集中,具工业价值。前人(广东省化工地质勘查院,2000)研究显示,径口矿段矿体主要赋存于F1断层上盘,棋子桥组灰岩地层内,存在明显的层控特征(图1)。本研究选取其 Fengcun Pb-Zn deposit is located in the southwestern segment of Qinhang metallogenic belt and in Lianjiang-Xinyi Upper Paleozoic fold system (Zhou Yongzhang et al., 2012). Field geological observation shows that the lead-zinc mine is composed of four ore sections including track mouth, mountain back, lower garden ridge and Dabo surface. Among them, the scale of ore section with a large mouth, mineralization is more concentrated, with industrial value. The predecessors (Guangdong Chemical Geological Prospecting Institute, 2000) have shown that the ore bodies of the Mine mouth mainly exist in the upper and lower layers of the F1 fault and the Qixizhashi limestone formation, with obvious stratification characteristics (Fig. 1). This study select it
