The types of peat mapped and encountered in the study area are (a) topogenous peat: also known as clayey peat, composed of plant remains and clastic sediments (with ash content) and formed in topographic depressions by plants that extracted nutrients from the mineral subsoil.
The topogenous peat is composed of slightly to moderately decomposed plant matters.

(2014) found no support for the inclusion of dune slack vegetation into the Caricion davallianae, even when this alliance was defined broadly and included also boreal topogenous
calcareous fens and arcto-alpine spring fens.
The chemistry of these coals clearly indicates that they were deposited as paralic topogenous
or low moor" swamps.

Recent deposits mainly consist of illite and kaolin clays in the lake basin, with pockets of shallow to moderately deep topogenous
peat occurring at the base of hills and in depressions between levees.
