吉林大横路钴铜矿床钴元素地球化学特征及矿床成因

吉林大横路钴铜矿床是90年代初发现的大型钴铜矿床，矿体受大横路复式向斜控制，呈层状似层状或鞍状产出，通过研究钴元素的地球化学特征及赋存状态，表明矿床中的钴元素主要分布在矿区大粟子组岩层中，并以独立矿物，类质同象等形式存在，结合矿床地质特征，研究了钴铜矿床中钴元素的地球化学行为，对探讨矿床成因和指导找矿有重要意义。

Cobalt Element Geochemical Characteristics of Dahenglu CobaltCopper Ore Deposit in Jilin Province and Its Genetics

Dahenglu Co-Cu deposit is a large Co-Cu deposit, it was discovered at the be-ginning of the nineties. The deposit is controlled by synclinore, their forms are layer, like layer or saddle. This paper studied the geochemical characteristics of cobalt element and its state which located the ore strata and distribution. The result proves that cobalt element is situated in the Dalizi formation. Cobalt element in ore existed form is indepent mineral and isomorphic replacement etc. Synthetic analyses The geological feature of the deposit was analysed synthetically. It is important to discuss the genetics and the practical prospect to study cobalt element geochemical act.
