| 摘 要： | 采用化学分析、X射线衍射、差热和热重分析、粒度与比表面积分析等技术、方法对5个我国南海深海泥样品进行了研究.结果表明,不同区域的深海泥中,其矿物组成有显著的差异,其中粘土矿物、石英、碳酸盐为主要的结晶相矿物;同时,非晶质粘土矿物广泛发育.深海泥中的矿物质具有粒径小、比表面积大、粘土矿物结晶程度差等特点,因此具有较好的活性.深海泥将是一种巨大的潜在非金属矿产资源.

| Abstract: | Five oceanic sediments were studied using chemical analysis, X_ray diffraction (XRD), differential thermal analysis (DTA), thermogravimetry (TG), and particle size and specific surface area analyses. Our present study shows that the mineral compositions of oceanic sediments vary with the locations. Clay minerals, quartz and carbonate are the main crystalline minerals and the non_crystalline clay minerals can be found in most samples. Minerals in oceanic sediments are poor_crystalline with small particle size and larger specific surface area. These materials should be of high quality for many industrial fields and are the important resource as non_metal minerals. |
