Abstract

The PanXi region in Sichuan province, Sounthwest China is famous for magmatic Fe-Ti-V oxide deposits in the country. The metallogenesis of the Panzhihua type V-Ti magnetite deposits remains controversial. Here we apply an interactive inversion technique on profiles of magnetic anomalies to study the deep geological structure of the Baima area. Combined with previous petrological and sedimentological studies on these rocks, the inversion results indicate that Baima iron deposits consist of several layered iron ore bodies. Different characteristics in the geometric forms of Panzhihua rock body and Baima rock body show different mineralization characters when forming magnetite ore layers under the gravity variation, resulting in different ore structures. Although the large aeromagnetic anomaly could be the signal of the buried huge iron ore bodies at depth in Panxi area, this has not been confirmed by deep drilling exploration. In order to solve this puzzle, we computed the aeromagnetic anomalies along profiles in the proven iron deposits of the Baima districts. The results reveal marked contrast between the calculated and observed anomalies. Based on these results and previous studies on the metallogenic features, we predict the presence of large iron ore bodies at depth beneath the Baima districts.
