| 中文摘要: |
| 西藏工布江达县亚贵拉铅锌银矿床位于隆格尔-工布江达弧背断隆带中,其主矿体呈层状、似层状,产于上石炭-下二叠统来姑组第二岩性段内岩性转换部位。文章认为亚贵拉铅锌银矿床在地质特征、地球化学特征和流体包裹体特征等方面与以往认为的夕卡岩-热液脉型、喷流沉积型-岩浆热液叠加改造型矿床有着明显的区别之处;亚贵拉矿床应属具后生成矿的层控型铅锌银矿床。 |
| 英文摘要: |
| Yaguila lead-zinc deposit in the Gongbujiangda county of Tibet is located in the back-arc fault up lift area of Longgeer-Gongbujiangda. The main ore bodies are layeroid occurring at places where lithology is transformed within the second lithologic member of Laigu formation of Upper Carboniferous-Lower Permian Series. The deposit differs evidently from skarn-veinlike hydrothermal type, Sedex-magmatic fluid reworking type deposits in aspects of geological, geochemical and fluid inclusion characteristics thus the authors consider it as a epigenetic stratabound lead-zinc-silver deposit. |
