摘要: 南海北部琼东南盆地西区乐东-陵水凹陷梅山组海底扇是当前天然气勘探重点领域,通过研究其岩石类型、轻/重矿物与地球化学特征,判断沉积源区性质,为储层评价及预测提供地质基础.结果表明:岩性以细砂岩为主,发育粉、中-粗砂岩,岩石类型为石英砂岩、岩屑石英砂岩、长石岩屑砂岩,重矿物组合表现为磁铁矿+锆石+电气石+白钛矿;由于发育高铁镁质矿物及粘土矿物,泥岩较砂岩SiO2含量明显低,Fe2O3、MgO、CaO、K2O含量与稀土总量偏高.说明源区富石英、贫钾长石且含有大量粘土矿物,主要为石英质沉积源区,局部为中性火成岩源区,且经历了低-中等程度的风化作用,是再循环沉积而成.Abstract: The submarine fans, which exist in the west area of Qiongdongnan basin of continental shelf in northern of the South China Sea, are the main area of gas exploration. Based on the analyses of the rock types, light and heavy mineral characteristics and geochemical characteristics, the research on estimating those fans provenances is more practical to the reservoir evaluation and prediction of the petroleum exploration. The study shows that the lithology is composed mainly of fine sandstones with minor amounts of siltstone, medium and coarse sandstones; the rock types are quartz sandstone, debris-quartz sandstone and feldspar-debris sandstone; the heavy mineral assemblages are magnetite, zircon, tourmaline and leucoxene. Compared with sandstone, the content of SiO2 in the mudstone is lower, while the total content of the rare earth elements is obviously higher because of the high ferromagnesian and clay mineral in mudstone samples. It is implied that the source material were rich in quartz, poor in feldspar and containing a large number of clay minerals, mainly quartz sediment and partial intermediate igneous rocks, mainly recycled sediments, whose source regions have experienced low to moderate weathering.
