现代海底热水喷出成矿现象的发现（Ｆｒａｎｃｈｅｔｅａｕｅｔａｌ·，１９７９；Ｓｉｍｏｎｅｉｔ，１９８５等）是近几十年来海洋地质研究最重要的成果之一。但是，由于多期多阶段的地质改造，古代的热水喷口至今尚未见过报道，笔者对大厂矿田长坡矿床各采矿坑道进行了系统
The discovery of modern seafloor hot-water mineralization (Francheteau et al., 1979; Simoneit, 1985) is one of the most important achievements in oceanographic research in recent decades. However, due to the multi-stage and multi-stage geological reconstruction, ancient hot water vents have not seen any reports so far. The author has carried out a systematic
