【摘要】：海南岛东部近海钛铁矿、锆英石等矿种成矿条件优越,分布较广,储量较大,有较好开发前景,为进一步研究海南岛东部近海沉积型矿产资源潜力,选则万宁保定海作为试点,采用单道地震和地质浅钻等手段进行外业勘查,通过对单道地震数据处理解译,发现研究区域沉积层较厚,并有随水深增大而增厚的趋势,地质浅钻岩芯显示钛铁矿物赋存于海底表层,且在孔深范围内钛铁矿品位随钻孔深度增大而增大,锆英石矿物品位随深度变化不明显。
[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.
