Diatoms as an indicator of bottom surface sediment dynamics in the southern Scotia sea
Keywords:sedimentation, bottom deposits, diatomite, diatoms, Middle Miocene, Scotia Sea
The study of diatoms from the sediments of the lower interval of column K97-18 in Scotia Sea it is revealed the combination of Late-Holocene and Miocene species in complexes, due to the abundance of inclusions of Middle Miocene diatoms in the rock. Age of re-deposition, transporters and ways of transportation are determined, and it is suggested possible localization of diatomite layers
