Recently acquired data lead to a revision of the structure around the apex of the Isparta Angle (area around Isparta). In the autochthonous/parautochthonous carbonate platform several blocks are identified as having followed distinctive palaeogeographical evolutions during Mesozoic times. These blocks are: the Kır Dağları, the Barla Dağ, the Söbü Dağ and the Bey Dağları. However, the latter two blocks cannot be considered as identical as previously believed. A major thrust fault may separate these blocks, which may be substantially allochthonous with respect to the relatively autochthonous Bey Dağları. Within the allochthon, in the Isparta Çay area, studied here, Mesozoic deep‐marine sequences are thrust duplicated many times. The tectonic history of the area is polyphased, the main events being in the Late Cretaceous (initiation of shortening), pre‐Miocene (Antalya Nappe emplacement), and Late Miocene/Pliocene (Aksu thrusting). The Aksu phase reactivates older thrusts and has given rise to the most prominent relief of the area (the Davras Dağ, 2600 m). Palaeogeographic reconstructions are proposed to take account of all the above data. Copyright © 2003 John Wiley & Sons, Ltd.

Pleistocene eruptive chronology of the Gölcük volcano, Isparta Angle, Turkey Chronologie des épisodes volcaniques pléistocènes du volcan Gölcük, Angle d'Isparta, Turquie

A thick sedimentary sequence comprising fluvial, lacustrine and volcano‐sedimentary rocks is present in the Neogene Beypazari Basin, central Anatolia. These units display considerable lateral facies variation and interfinger with alkaline volcanic rocks along the north‐eastern margin of the basin. The uppermost Miocene Kirmir Formation contains numerous evaporite horizons. The evaporite sequence is up to 250 m thick and may be divided into four lithofacies. In ascending stratigraphical order these are: (1) gypsiferous claystone facies, (2) thenardite‐glauberite facies, (3) laminar gypsum facies and (4) crystalline gypsum facies. These facies interfinger with one another laterally along a section from the margins to central parts of the basin. The lithological and sedimentological features of the Kirmir Formation indicate fluvial, saline playa mudflat, hypersaline ephemeral playa lake and very shallow subaqueous playa lake depositional environments, which probably were influenced by alternating semi‐arid and evaporative conditions.
