摘要
在GIS技术的支持下,对羌塘盆地砂岩型铀矿成矿条件进行了初步调查和分析,调查内容侧重于区域地质背景、目标层选择、铀源、古水动力、古气候等方面。研究表明,羌塘盆地基本具备砂岩型铀矿成矿条件,盆地砂岩型铀矿找矿目标层主要为夏里组,其次为雪山组和雀莫错组,有利区域是东北斜坡带和中央隆起北缘。
On the support of GIS, preliminary investigation and analysis on metallogenic condition of sandstone-type uranium deposit in Qiangtang Basin have been carried out, special emphasis is laid on regional geological setting, selection of target horizon, uranium source, palaeohydrodynamics, palaeoclimate, etc. It is concluded that Qiangtang Basin has basic condition for forming sandstonetype uranium deposi deposit. The target t, and a certain potential for interlayer-oxidation zone sandstone-type uranium layer is Xiali Formation, Xueshan Formation and Quemocuo Formation. The is the northeastern slope zone and the northern fringe of central uplifting zone.
