【摘要】：大洋鉆探資料證實,現(xiàn)代海底多金屬硫化物分布范圍廣泛、儲量大,是具有巨大開發(fā)潛力和遠景的海底礦產(chǎn)資源。根據(jù)水深、地質(zhì)構(gòu)造、擴張速率、地球物理以及火山地震等區(qū)域性調(diào)查數(shù)據(jù),分析了印度洋中脊多金屬硫化物成礦地質(zhì)條件、控礦因素和地球物理異常信息,提取了9項找礦證據(jù)因子,建立了區(qū)域找礦有利條件組合模型。運用證據(jù)權(quán)重法,對印度洋中脊多金屬硫化物資源進行了基于數(shù)據(jù)驅(qū)動的定量預(yù)測與評價。研究認為,最有利區(qū)(Ⅰ類)占工區(qū)面積的29.77%,比較有利區(qū)(Ⅱ類)占18.12%。
[Abstract]:Ocean drilling data confirm that modern seabed polymetallic sulphides are widely distributed and have large reserves, which are potential and prospective seabed mineral resources. Based on the regional survey data of water depth, geological structure, spreading rate, geophysics and volcanic earthquake, the ore-forming geological conditions, ore-controlling factors and geophysical anomalies of polymetallic sulphides in the middle ridge of the Indian Ocean are analyzed. Nine factors of ore-prospecting evidence were extracted and a combination model of favorable conditions for regional prospecting was established. The data driven quantitative prediction and evaluation of polymetallic sulphide resources in the middle Indian Ocean ridge were carried out by using the evidence weight method. The results showed that the most favorable area (class 鈪，
