| 摘 要： | 本文研究和分析了川北砂岩和康滇地轴几个铀矿床和矿化地段的各种地球物理场分布特征与铀矿化的关系,及其反映的铀成矿可能性。充分利用和分析研究工作区现有的大量放射性测量及航磁、重力测量资料,总结和建立铀成矿的区域物(化)探判据:高变异、剩余值、零值线、过渡带、富铀体、复合晕。利用成矿判据在区域和矿区成矿预测中划分成矿有利区、段,为区域找矿和矿床扩大提供了可靠的依据。

| Abstract: | This paper studies and analyses the distribution characteristics of various geophysical fields and their relation with uranium mineralization as well as the uranium metallogenetic possibility reflected from them in several uranium deposits and mineralized portions in northern Sichuan's sandstone and the Xikang-Yunnan Axis. By fully utilizing,analysing and studying the existing numerous data from radiometric, aeromagnetic and gravity survey, regional geophysical (geochemical) criteria of uranium metallogenesis such as high variation, surplus value, zero value line, transitional zone, rich uranium body and composite halo are summarized and established. During the regional and ore district metallogenetic prognosis, metallogenetic criteria were used to divide favourable prospective areas and portions, thus providing reliable basis for regional prospecting and deposit extension. |
