After the decline of the Baltic Ice Lake lacustrine sediments (lime and gyttja
up to 1 m in thickness) were deposited into the Varudi depression, followed by peat accumulation in the Holocene (Suuroja et al.
It was made on a gyttja
bulk sample taken from a borehole which was situated 740 m NW from the Palanga site (Fig.
2009), including clay at the bottom of the sequence, followed by a transition to a more organic gyttja
The percussion coring of the basin further showed that coarse diamicton is overlain by coarse, granite-rich, moderately sorted sediment which, in turn, is overlain by alternating layers of gyttja
and wetland sediment.
deposition initially occurred in the third bog and then was followed by marl deposition.
The surface was a very soft and porous gyttja
up to a depth of about 0.
The sediments in all the studied cores consisted of dark-brown unconsolidated, highly porous, homogeneous gyttja
The analysed sediments consisted of brownish gyttja
of high organic matter content (loss-of-ignition (LOI) 60-86%) and high porosity (95-98% of water).
In buried conditions patches of peat and gyttja
were sealed and preserved up to the present, offering material for radiocarbon dating.

Surficial organic deposits are not common on the Ohio till plain; however, three houses in the north Columbus neighborhood of Sharon Woods had to be leveled owing to structural damage from sinking into peat and gyttja
