Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain.
