Résumé
The study area. located north of Konva (Central Turkey), is composed of
Silurian to Cretaceous metamorphosed rocks. The lower unit of the oldest
formation (Silurian-Early Permian) is mostly made up of Silurian-Early
Carboniferous metacarbonates. These rocks pass laterally and vertically
to Devonian-Early Permian series having continental margin, shallow
water and pelagic characteristics. They are intruded or juxtaposed to
different kinds of metamagmatic rocks. which show MORB. continental arc
and within plate characteristics. The Palaeozoic units are covered
unconformably by Triassic-Cretaceous metasedimentary units. All these
rocks are overthrusted by Mesozoic ophiolites. The Palaeozoic sequence
can be seen as a northern Palaeotethys passive, then active margin. The
northward subduction of the Palaeotethys ocean during the
Carboniferous-Triassic times, induced the development of a magmatic arc
and fore-arc sequence (Carboniferous-Permian). Before the Early Triassic
(?Late Permian) time. the fore-arc sequence was uplifted above sea level
and eroded. The Triassic sequences are regarded as marking the onset of
back-arc opening and detachment of the Anatolian Konya block from the
active Eurasian margin. Finally. a suture zone formed during the Carman
between the Konya region and the Menderes-Tauride Cimmerian block due to
the closing of Palaeotethvs. This geodynamic evolution can be correlated
with the evolution of the Karaburun sequence in western Turkey.
