摘要
大降坪矿床存在着两种截然不同的矿石类型,Ⅲ号矿体条带状矿石是同生热水沉积作用形成,Ⅳ号矿体块状矿石是后期热液叠加改造形成。两者在微量元素、硫、铅同位素及流体包裹体等地球化学性质方面各具特征。通过矿床地质地球化学等方面研究表明:该矿床为一典型的同生热水沉积-后期热液叠加改造型层控矿床。
There are two diametrically different ore types in the Dajiangping oredeposit:the banded ore in No.Ⅲ orebody was formed by syngenetic hot-waterdeposition, whereas the massive ores in the No. Ⅳ orebody by late hydrothermalsuperimposition and reformation.The two types of ores are quite different fromeach other in such aspects as trace elements,sulfur and lead isotopes and fluidinclusions, Geological and geochemical studies show that the ore deposit is atypical syngenetic hot water deposition-late hydrothermal superimpositionand reformation type stratabound deposit.
