| 摘 要： | 对内蒙古陶来托钼多金属勘查区进行地质、地球物理、地球化学综合找矿信息的提取来评价矿区找矿潜力。结果表明,陶来托钼多金属矿是一个以斑岩型钼矿为主的勘查区,发现了斑岩型钼矿床及多处热液脉型铅锌银矿(化)点。成矿岩体为早白垩世花岗斑岩,控矿构造为北东-北北东向断裂。斑岩型钼矿化区与环状激电异常和环状磁异常对应性较好,显示出中低视极化率异常为矿致异常的特征。1∶5万化探异常元素由钼矿化区至铅锌银矿化区表现出Mo、W—Ag、Pb、Zn的侧向分带特征。根据综合找矿信息提取及斑岩型矿床成矿系列建立,指出区内钼矿找矿潜力较大,并预测钼矿区北西侧为热液脉型铅锌银矿的成矿有利地段。

| Abstract: | The geological, geophysical and geochemical information were extracted to evaluate the prospecting potential of the Taolaituo molybdenum polymetallic prospecting area in Inner Mongolia. The results show that the Taolaituo molybdenum polymetallic district was dominated by porphyry molybdenum mineralization,and the porphyry molybdenum deposits and numerous polymetallic vein type Pb-Zn-Ag mineralization points have been discovered. The ore-forming rock mass is Early Cretaceous granite porphyry, and the ore-controlling structure is NE-NNE-trending fault. The molybdenum mineralization zone is well correlated with ring induced polarization and annular magnetic anomalies,which shows that the anomaly of medium-low apparent polarization is the characteristic of anomaly caused by ore mineralization. 1:500 00 geochemical anomalies have zonation characteristics of Mo-W→Ag-Pb-Zn from the molybdenum mineralization zone to lead-zinc-silver mineralization zone. Based on the comprehensive prospecting information extraction and the establishment of porphyry type metallogenic series,it is concluded that it has a good prospecting potential of molybdenum deposits in this area,and it is also predicted that the north-west side of molybdenum deposits is the favorable location of the polymetallic vein type Pb-Zn-Ag. |
