凡口铅锌矿床位于广东省韶关市仁化县,20世纪60年代发现以来,累计探明铅锌储量近千万吨。矿床成因争议较大,其成因认识共经历了几个发展阶段,其中较具代表性的观点有:远成低温热液型(赖应篯,1981)、同生卤水沉积成矿说(吴延之等,1982;郑庆年,1996)、沉积—渗流热卤水交代成矿说(吴健民等,1987)、沉积—成岩—成岩后改造富集成矿说(赖应篯,
Fankou lead-zinc deposit is located in Renhua County, Shaoguan City, Guangdong Province. Since the discovery in the 1960s, a total of nearly ten million tons of lead and zinc reserves have been proved. The genesis of the deposit is quite controversial. The causes of its formation have undergone several stages of development. Among them, the more representative ones are the Yuancheng low-temperature hydrothermal type (Lai Yingtao, 1981), the syngenetic brine sedimentary mineralization (Wu et al. , 1982; Zheng Qingnian, 1996), sedimentary-hydrothermal hydrothermal replacement metasomatism (Wu Jianmin et al., 1987), sedimentary-diagenesis-
