Abstract

Limestone olistoliths of
different size are commonly observed in the elastics of Karasenir formation
(Amasya) which is unconformably overlain by the Liassic deposits. In two of
these olistoliths, conodont faunas belonging to eurekaensis, delta and Pesavis
zones of early Devonian (Lochkovian) were determined. Typical Permian algaes
(Gymnocodiacea) were described in thin sections of a dark gray limestone
olistolith. Since it contains early Devonian and Permian olistoliths and
unconformably covered with the Liassic units, the age of Karasenir formation is
believed to be Triassic. Including of underlying metamorphic rocks to the
Karakaya complex necessities also including of Karasenir formation as their
stratigraphic continuation
