摘要: 深水碳酸盐沉积包括深水重力流作用形成的异地沉积和非重力流沉积, 在非重力流沉积中又有深水牵引流(等深流、内波、内潮汐等) 沉积和静态原地碳酸盐沉积。深水碳酸盐沉积与重力流及等深流活动有关, 也受控于表层水碳酸盐产率、陆源物质的稀释作用及深水对碳酸盐的溶解作用。大量研究表明, 深水碳酸盐沉积对海平面升降与气候变化响应明显,无论是重力流或非重力流沉积均有体现, 通过深水碳酸盐沉积研究可以提取地质历史时期环境变化的信息, 同时,某些深水碳酸盐沉积岩中蕴藏着丰富的石油、天然气和其他沉积矿产。由此开展此项研究具有重要的理论和实际意义。

Abstract: Deep water carbonate sediments include allochthonous carbonate sediments released from shallow water by gravity flow and carbonate contourite and static autochthonous deep sea carbonate sediments. Deep water carbonate sediments were controlled by gravity flow, contoured flow and also controlled by carbonate productivity of surface water, dilution of siliciclastic from the land, and carbonate corrosion under deep sea. Most researches indicate that deep water carbonate sediments perfectly response to sea level variations and climatic changes no matter whether gravity flow or no gravity sediments. The information about environmental evolution can be obtained through studying on deep water carbonate sediments. Meanwhile, there are rich oil, natural gas and other sedimentary mineral resources in deep water carbon ate rocks. So, there are important theoretical and applied significances.

Key words: deep water carbonate sediment, sea level variation, climatic change, sedimentary response
