| 摘 要： | 热海热田内热泉水和各类热水沉淀物中不同程度地富含Ａｕ、Ａｇ、Ａｓ、Ｓｂ、Ｈｇ、Ｔ１微量元素，金的富集与含黄铁矿的水热角砾岩、硅质泉华更为密切。热田内水热爆炸和沸腾作用广为发育，Ａｕ，Ａｇ、Ａｓ、Ｓｂ、Ｈｇ、Ｔ１微量元素组异常可能是热泉型金矿化浅部的地球化学特征。

| Abstract: | Various amounts of trace elements Au,Ag,As,Sb,Hg and Tl are con-centrated in spring waters and hydrothermal precipitants in the Rehai Hot Sea)geothermal field. The enrichment of Au is closely related to the existence of pyrite-bearing hydrothermal breccias and siliceous sinter. Hydrothermal eruptions and boiling in the Rehai geothermal field were widely developed. The abnormal of the trace element suite of Au,Ag,As,Sb,Hg and T1 probably is the geochemical char-acteristics for shallow part of a hot spring gold deposits. |
