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.

Key words: soil thermomagnetic component survey, soil granule component survey, iron and manganese oxide survey, grassland area, eastcentral Inner Mongolia
