摘要
根据矿床地质地球化学等方面的研究,认为该矿床成矿物质来源于深部地壳或上地幔;通过海底火山喷流作用,在酸性相对还原的热水沉积盆地中沉积成矿。成矿流体来源于岩浆水,并有海水混入。红碧玉、重晶石等具有喷流岩的特征。矿床成因属于海底火山喷流—热水沉积矿床。
According to the geological - geochemical research of the deposit, the author holds that the metallogenic matters of the deposit originated from deep - seated crust or upper mantle. It was formed by sedimentation in hydrothermal sedimentary basin with relative reduced acidity by the action of submarine volcano plume. Metallogenic fluid stemed from magmatic water and mixed with seawater. Red carneol and barite etc. have the features of plume rocks. The origin of the deposit is attributed to submarine volcano plume- hy-drothermal sedimentation.
