| 中文摘要: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、铅同伍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-期热液叠加改造型层控矿床。 |

| Abstract:There are two diametrically different ore types in the Dajiangping ore deposit: the banded ore in No. Ⅲorebody was formed by syngenetic hot-water deposition. Whereas the massive ores in the No.Ⅳorebody by late hydrothermal superimposition and reformation. The two types of ores are quite different from each other in such aspects as trace elements, sulfur and lead isotopes and fluid inclusions. Geological and geochemical studies show that the ore deposit is a typical syngenetic hot water deposition-late hydrothermal superimposition and reformation type stratabound deposit. |
