Potassium-rich volcanic rocks in the Isparta area (SW Turkey) consist mainly of older (Pliocene) volcanic rock suites (e.g., lamprophyre, basaltic trachyandesite, trachyandesite, trachyte) and younger (Quaternary) caldera forming lava dome/flows (e.g., tephriphonolite, trachyte) and pyroclastics (ash/pumice fall deposits and ignimbritic flows). The magnetic susceptibility (K) was performed for both groups. The magnetic susceptibility value of the less evolved rocks characterized by SiO 2 < 57 wt% (e.g., basaltic trachyandesite, tephriphonolite, lamprophyric rocks) and having mostly mafic phenocrysts such as pyroxene, amphibole, and biotite-phlogopite is over 10 (10 −3 [SI]). Fine to medium-grained and subhedral to anhedral opaque minerals are scattered especially in the matrix phase of the less evolved volcanic rocks. However, the K value of the more evolved rocks (e.g., trachyte and trachyandesites) with SiO 2 over 57 wt% vary between 0.1 and 28, but most of them below 10. SI values are negatively correlated with SiO 2 , Na 2 O, but positively correlated with Fe 2 O 3 , CaO, MnO, P 2 O 5 and MgO contents, suggesting inverse variation of SI with fractionation of potassic magma. That is to say that less evolved volcanic rocks have relatively higher magnetic susceptibility values in the volcanic suite. Fine to medium-grained and subhedral to anhedral Fe-Ti oxides are scattered mainly in the matrix phase of the less evolved volcanics, presumably cause the pronounced relatively higher magnetic susceptibility.

“…This layer resulted from an eruption that resulted in equivalents deposits 25 km from the Gölcük volcano which is situated some 25 km to the West. The eruption is probably related to the growth of the last trachytic domes that have been found (Platevoet et al, 2008). Kazanci (1993) indicated that, south of Lake Egirdir, pyroclastic-fall sediments occur within the successions of alluvial cones that advance toward the lake, and that these pyroclastics are products of the Pliocene Gölcük (Isparta) volcanism, thus implying that the lake basin developed prior to the middle-late Pliocene.…”

The tectonic evolution of Lake Eğirdir, West Turkey

Lake Eğirdir is one of the most important fresh-water lakes of Turkey. It has a tectonics-related origin. The area formed under a roughly N-S compressional tectonic regime during the Middle Miocene. The stresses caused slip faults west and east of Isparta Angle, and the lake formed at the junction of these faults. The area subsided between normal faults, thus creating the topographic condition required for a lake. The lacustrine sediments have fundamentally different lithologies. After the Late Miocene, central Anatolia started to move westwards, but western Anatolia moved in a SW direction along the South-western Anatolian Fault , which we suggest to have a left lateral slip, which caused that the Hoyran Basin moved t7 km towards the SW and rotated 40º counterclockwise relative to Lake Eğirdir.
