【摘要】：海南島東部近海鈦鐵礦、鋯英石等礦種成礦條件優(yōu)越,分布較廣,儲(chǔ)量較大,有較好開發(fā)前景,為進(jìn)一步研究海南島東部近海沉積型礦產(chǎn)資源潛力,選則萬寧保定海作為試點(diǎn),采用單道地震和地質(zhì)淺鉆等手段進(jìn)行外業(yè)勘查,通過對(duì)單道地震數(shù)據(jù)處理解譯,發(fā)現(xiàn)研究區(qū)域沉積層較厚,并有隨水深增大而增厚的趨勢(shì),地質(zhì)淺鉆巖芯顯示鈦鐵礦物賦存于海底表層,且在孔深范圍內(nèi)鈦鐵礦品位隨鉆孔深度增大而增大,鋯英石礦物品位隨深度變化不明顯。
[Abstract]:The ore forming conditions of ilmenite and zircon in the east coast of Hainan Island are superior, the distribution is relatively wide, the reserves are large, and there is a good prospect of exploitation. In order to further study the potential of sedimentary mineral resources in the eastern part of Hainan Island, the Wanning Baoding Sea is selected as a pilot project. By means of single channel earthquake and shallow geological drilling, and by processing and interpreting the single channel seismic data, it is found that the sediment layer in the study area is thicker and has a tendency of thickening with the increase of water depth. The geological shallow drilling core shows that the ilmenite occurs in the surface layer of the seabed, and the grade of ilmenite increases with the depth of the borehole in the range of the hole depth, but the zircon mineral site does not change obviously with the depth of the borehole.
