2、很大找礦空間,西部部分地區(qū)甚至是勘查空白。在很多已知礦集區(qū)和鐵礦找礦遠景區(qū),都有很大的找礦潛力。對鐵礦石的高位需求、較大的鐵礦資源潛力和次貸危機,對新一輪鐵礦勘查提出了機遇和挑戰(zhàn)。新一輪鐵礦勘查布局應(yīng)為:東部以重點成礦區(qū)帶隱伏礦找礦為主,西部以重要成礦區(qū)帶新區(qū)找礦為主,加強大中型鐵礦山深部和外圍的找礦。同時,要加強鐵礦成礦理論和勘查技術(shù)方法研究,加強航磁數(shù)據(jù)更新和資料二次開發(fā),努力創(chuàng)新地質(zhì)勘查機制。關(guān)鍵詞:鐵礦;潛力;新一輪鐵礦勘查;思考中圖分類號:P628131文獻標識碼:A文章編號:1004-4051(2009)07-0058-04Consi
