The Submerued Peat in Seltjörn
by Sigurdur Thorarinsson.
Submerged peat along the coast of the inner part of Faxaflói lias been
known for centuries and is mentioned in the literature for the first time in
1746. It has been studied especially by G. G. Bárdarson, who regarded the
occurrence of this peat as a proof of a landsinking in late Postglacial Tirne.
His opinion has been accepted by those who have later discussed this pro-
blem, with the exception of T. Einarsson, who has argued against it and
maintained that this peat is no proof of submergence. In spite of the role the
submerged peat has played in the discussion on the shore line development in
SW Iceland, no microscopic study of this peat has been carried out until now,
nor lias anything been known with certainty about its age.
One of the places where subnterged peat occurs is the inlet Seltjörn on the
