| 摘 要： | 近年来国外发现了许多大型块状硫化物矿床，而我国进展还不大。原因之一是我们对这类矿床的地质特征，成矿条件尤其是找矿标志研究还不够。这是一类成矿物质通过热液作用在海底沉积而成的特殊矿床，故在找矿勘探讨既要研究沉积矿时形成的原生晕，又要研究热液经过围岩时蚀变而产生的次生晕?Ｍｎ晕，Ｔｌ，Ｈｇ，Ｂａ，Ａｓ和Ｚｎ等元素的异常，络合剂元素的富集，微量元素的分布，铅同位素，岩石化学异指数尤其是块状硫化物Ｃｕ矿中

| Abstract: | Many massive sulfide deposits that have been found abroad were formed by deposition of sulfides from hydrothermal system on the sea floor,and combined with sedimentation and alteration. Therefore,both primary halo in strata and secondary halo in altered rocks surroundtng the ore deposits are useful and should be studied. Mn halo ,anomaly of T1 ,Ba ,Hg ,As and Zn, enrichment of complex anions, distribution feature of minor mineralization elements,Co/Ni ratio of pyrite, lead isotope and ,especially,the adding of Mg and leaching of Na in massive sulfide Cu deposits ,are practical indicators for exploring massive sulfide deposits. |
