The origin of sapropels in the Eastern Mediterranean Sea

在ODP969F-1H孔的岩心回收了430KYR，包括从S11到S1腐蚀物。多指标分析表明，富有机腐泥岩S3、S4、S5和S6沉积于低盐度地表水和高输入陆源有机质的滞留底水条件下。S7的沉积条件与它们相似，但底水条件不同，需要溶解有机通量，有机低腐蚀物S1、S10和S11夹在略红棕色的纳米化石软泥中，形成于较暖的混合表层水和以海相有机质为主的死水中。

The core at ODP Hole 969F-1H recovered 430 kyr including from S11 to S1 sapropels. The multi-proxies analysis revealed that the organic-rich sapropels S3, S4, S5, and S6 were deposited at the conditions of low salinity surface water and stagnant bottomwater with high input of terrigenous organic materials. The depositional conditions of S7 was similar of them but with different bottomwater conditions in which organic flux should be dissolved.The organic-low sapropels S1, S10, and S11, interbedded in slightly reddish brown nannofossil ooze, were formed under warmer mixed surface water and stagnant bottomwater with dominant of marine-origin organic materials.
