为了从遥感角度对西澳大利亚哈默斯利盆地的沉积变质条带状含铁建造( banded iron formation,BIF)型铁矿进行深入研究,利用ETM图像对皮尔巴拉地块进行地质矿产解译,采用ASTER图像对目标区域进行矿化蚀变信息提取；结合传统地质矿产理论及相关文献,对区内BIF型铁矿的遥感地质特征及其成矿机理进行深入解剖、对比和研究,在此基础上建立了BIF型铁矿的遥感地质找矿模型；并圈定了找矿远景区,以期能在BIF型铁矿找矿(前期)技术方面取得突破,为寻找BIF型铁矿提供技术支持与帮助。具有现实验证意义的是,在所圈定的找矿远景区进行野外调查时发现,澳大利亚力拓集团已经在纽曼—必和必拓C区远景区内筹建一处大型铁矿,前期平地工作已基本完成。

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.
