亻表口牡蛎礁剖面原位胶结的牡蛎礁层之间有 6层粉沙夹层 ,这一层序被认为是 6 5 0 0~ 30 0 0aB .P .多次海面波动的反映 ,该剖面的研究被认为是近年来全新世海面研究的重大成果。然而 ,组成蛎礁的属种长牡蛎和近江牡蛎产于低潮线附近至十余米水深 ,生活的盐度很广 ,可以在盐度 10‰~ 30‰的海区栖息。它们在指示沉积物形成的深度上虽有一定意义 ,但并不是海水深度良好的指示标志。其兴衰不是由于海面变化造成的。泥砂沉积速率的变化是导致牡蛎礁与砂层交替出现的原因。亻表口牡蛎礁剖面既不能反映 6 5 0 0~ 5 0 0 0aB .P .存在高海面 ,也不能说明 5 0 0 0~ 30 0 0aB .P .海面波动频繁。
There are 6 layers of silt sandstones between the in situ cemented oyster reefs in the oyster reef profile of this site. This sequence is considered to be a reflection of multiple sea surface fluctuations of 6500-3030baB, The study is considered to be a major achievement of Holocene sea research in recent years. However, the species Oyster Oysters and Oyster Oysters, which constitute the oyster reefs, are produced near the low tide line and reach a depth of more than ten meters. The salinity of life is very broad and they can inhabit the sea areas with salinities of 10 ‰ to 30 ‰. Although they have some significance in indicating the depth of sediment formation, they are not good indicators of seawater depth. Its rise and fall is not due to changes in the sea. The change of sediment deposition rate causes the alternation of oyster reef and sand layer. The oyster reef profile at the surface of the mouth neither can reflect the high sea level of 6500 ~ 5000bP, nor does it indicate that the sea surface fluctuates frequently from 5000to 300oC.
