| 中文摘要: |
| 西藏工布江达县亚贵拉矿床位于隆格尔－工布江达弧背断隆带中,主要矿体呈层状、似层状,主要产于上石炭-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矽卡岩-热液脉型、喷流沉积型-岩浆热液叠加改造型矿床特征有着明显的区别之处,亚贵拉矿床应属具后生成矿特征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 orebodies exists as layer and stratabound. The deposit is occurred in the lithology transformation of the second lithologic member of upper Carboniferous-lower Permian Laigu group. This article considers that the aspects of geological, geochemical and fluid inclusion characteristics of Yaguila deposit is defferent from skarn-veinlike hydrothermal type and sedimentary exhalative-magmatic hydrothermal deposit. Yaguila deposit should be a stratabound lead-zinc deposit with epigenetic metallization. |
