大洋盆地中的有机物质有三个主要来源,即海相浮游生物、陆相较高等植物和在地表条件下经过强烈分解尚未分异的残留有机物。海相有机物质的时代及区域分布主要是受保存条件控制的。在深海中,有机物质的积聚作用主要发生在受限制的缺氧盆地内;也可发生在莱些局部条件下导致有机物质供给量大于细菌分解能力的广海中。中度分解的陆源有机物质来自陆地植物,并为河流和流水作用带走。这些有机物质主要沉积于河口扇的沉积物中。残留的有机物质搬运前在地表条件下已被强烈分解。它们由同生的或再沉积的物质组成。这些物质不会再分解,并可呈大面积分布,与局部的环境无关。
There are three main sources of organic matter in the oceanic basin, namely marine plankton, plants with higher terrestrial levels, and residual organic matter that has not yet been differentiated through intensive decomposition under surface conditions. The temporal and regional distribution of marine organic matter is largely controlled by conservation conditions. In the deep ocean, the accumulation of organic matter occurs mainly in restricted anoxic basins; it can also occur in Guanghai, where the supply of organic matter is greater than the bacterial decomposition capacity under some local conditions. Moderately decomposed land-derived organic matter comes from land-based plants and is taken away by rivers and flowing water. These organic materials are mainly deposited in estuaries fan deposits. Residual organic matter has been strongly decomposed under surface conditions prior to handling. They consist of symbiotic or redeposited substances. These substances will not decompose, and can be distributed in large areas, and the local environment has nothing to do.
