柴达木盆地南缘三湖地区新生代构造特征及其对砂岩型铀成矿的影响
Tertiary Structural Characteristics of the Sanhu Region at the Southern Margin of the Qaidam Basin and Their Influence on Sandstone-Type Uranium Mineralization
摘要
Abstract
The Sanhu area of the Qaidam Basin is located on the northeastern margin of the Qinghai-Tibet Plateau,belongs to the southern slope zone of the Qaidam Basin.Clarifying the relationship between its tectonic characteristics and sandstone-type uranium mineralization is key to evaluating the uranium resources in this region.This paper systematically reviews the Cenozoic tectonic features of the study area,summarizes research progress on sandstone-type uranium deposits,elaborates on the uranium mineralization conditions in the Sanhu region,and analyzes the role of tectonic features in uranium mineralization.Thick sandstone bodies developed on the southern slope of the Sanhu within the Shizigou and Qigequan Formations of the study area,aligning well with the longitudinal anticlinal structure;simultaneously,the intense Late Cenozoic uplift of the Eastern Kunlun Orogenic Belt in the south has continuously supplied uranium sources to the basin.Uranium occurrences such as Huangshi and Huangfengshan have been identified,providing important clues for exploration.A comprehensive analysis of the relationship between the study area's tectonic features,uranium sources,lithology and facies,and thick,large-scale sand bodies and sandstone-type uranium mineralization indicates that the Sanhu region possesses excellent uranium mineralization potential and promising exploration prospects.关键词
