Abstract In this paper, the satellite remote sensing interpretation of geology and minerals in Pilbara Craton of Western Australia was carried out by using ETM satellite remote sensing images, and the mineral alteration information of the target area was extracted by using ASTER satellite remote sensing images so as to do further research on metamorphosed sedimentary type(banded iron formation, BIF-type)iron deposits in Hamersley Basin of Western Australia from the remote sensing angle. In combination with traditional theory of geology and mineral resources and relevant literatures, the remote sensing geological characteristics and metallogenic mechanism of BIF- type iron deposits in the study area were dissected, contrasted and studied. On such a basis, the remote sensing geological prospecting model of this type of iron deposits was established, and the prospective areas were delineated. It is expected to make a breakthrough in prospecting technology of BIF-type iron deposits and to provide a practical guide in search for this type of iron deposits. During the field investigation of the above-mentioned prospective areas, the authors found that Rio Tinto group in Australia already intended to build a large iron mine in C area of Newman-BHP Billiton and had basically completed the field leveling work, which verifies the practical significance of this paper.
