松辽盆地克山地区航放异常特征及铀成矿条件分析
Abnormal characteristics and analysis of uranium metallogenic conditions in Keshan area of Songliao basin
摘要
Abstract
In order to screen the favorable area of uranium mineralization and explore the prospect of uranium deposit in Keshan area,1:50000 aviation radioactiue measurement anomaly verification work was conducted with the relevant geological data,the uranium metallogenic conditions in Keshan area was analyzed from the aspects of aerial radioactivity characteristics,geological characteristics,energy spectrum characteristics and soil radon concentration characteristics.The results show that the area is close to the Xiaoxing'anling area,and the basin caprock has a high initial uranium content and excellent uranium source conditions.The strata are widely distributed and gently dripped,and the developed faults can be acted as the channel for deep hydrocarbons migration.The local erosion of the surface is strong and forming a structural skylight.The favorable sand bodies for mineralization developed on a large scale,accompanied by epigenetic transformation and uranium enrichment.The aerial magnetic anomalies concentrated in Keshan area,and the inferred structures are verified by aerial magnetic survey.The deep radioactive information is prominent,which provides useful clues for the exploration of sandstone-type uranium deposits and the identification of favorable exploration sections.关键词
