航磁分形方法在地浸砂岩型铀矿床预测中的应用探讨

Discussion on the application of aeromagnetic data fractal in predicting in-situ leachable sandstone-type uranium deposits

根据层间氧化带砂岩型铀矿床上方存在高频弱磁异常的标志特征,研究了应用分形方法提取铀矿化引起的航磁弱信息的方法技术。在巴彦浩特盆地锡林凹陷内,结合区域成矿地质环境,应用航磁分形方法提取“矿致”异常,完成了砂岩型铀矿远景靶区初选。

According to the character of high frequence weak magnetic anomaly over the inter-layered oxidized zone type uranium deposits, fractal technique aimed to extract aeromagnetic weak information caused by uranium mineralization is studied in this paper. Integrating with regional metallogenetic geological environment in Xilin depression of Bayanhaote Basin, the authors apply fractal technique to extract aeromagnetic anomalies related to mineralization, and finish the primary prediction of perspective target of sandstone-type uranium deposits.
