| 摘 要： | 比如盆地位于青藏高原中东部，是一个经历了多期构造活动、挤压叠合改造，以地层与断裂为界的中生代盆地。燕山晚期一喜山期以来，盆地由于经历了剧烈的构造变形，地层急剧抬升，并均已遭受区域变质，大多发生板岩化。盆地中未发现有疏松砂岩层，这对地浸砂岩型铀矿成矿不利。但从已发现的铀异常点、带及水系沉积物异常来看，表明盆地还是有热液型、变质岩型、花岗岩型铀矿的找矿前景。

| Abstract: | The Biru basin is located in the central east of the Qinghai-Tibet Plateau. It is a Mesozoic basin to be subjected to multiple phases of structural activity. Strong tectonic deformation and regional metamorphism since the Late Yanshan-Himalayan epoch is unfavorable to ore-formation of ISL-amenable sandstone-type uranium deposits. The known U geochemical anomalies and geological conditions show perspective of hydrothermal, metamorphic and granite-hosted types of U mineralization. |
