在远离加拿大太平洋海岸的“Explorer”(勘察者)海岭地区发现了约150万吨的Cu和富Zn的硫化物.1984年6月至7月用潜水艇在那里进行勘查,结果在1800-1950米深处有17处新发现,最大一处宽达150-200米,另一处厚达7米.其成因与热液喷发有关,在成分和结构上与某些陆上的基底金属矿床相似.沿海岭的 Approximately 1.5 million tonnes of Cu and Zn-rich sulphides were found in the “Explorer” (Surveyor) Ridge remote from the Pacific coast of Canada and were surveyed there by submarines from June to July 1984. Results were 1800 17 new discoveries in the depth of -1950 m, the largest one being 150-200 m wide and the other 7 m thick, due to hydrothermal eruptions, which are structurally and structurally related to some onshore base metals The deposit is similar
