| 摘 要： | 内蒙古中东部草原景观区成矿地质条件有利,但由于风成砂等的覆盖,导致常规地球化学勘查在该地区找矿中受到限制。在内蒙古东乌旗1017高地进行了土壤热磁组分测量、土壤细粒级组分测量和铁锰氧化物态测量方法的对比试验,结果表明,3种方法均能有效地圈出地球化学异常,而且3种方法圈定的异常吻合程度很好。相比较而言,土壤热磁组分测量能够显著提高异常强度,有利于发现微弱的地球化学异常信息,显示出该方法在草原景观区良好的应用前景。

| Abstract: | The ore-forming conditions in grassland area,east-central Inner Mongolia is favorable,but due to the coverage of the aeolian sand,the application of standard geochemical exploration methods is limited for prospecting in the region.Soil thermomagnetic component survey,soil granule component survey and Fe-Mn oxide survey are conducted for comparative study in 1017 highland,Dongwuqi,Inner Mongolia.The results indicate that the three measuring methods all can delineate the anomalies effectively;moreover,the anomalies determined by the three methods are fairly similar.Comparatively speaking,soil thermomagnetic survey can enhance the anomaly intensity and detect weak geochemical abnormal information,which displays the good application perspective in grassland area. |
