“…Various volcanic and volcano-sedimentary units form in the region, namely, ignimbrite, nuée ardentes, volcanic breccias, agglomerates, tuffs, tuffites, lava flows, lava domes, dikes and sill, with composition of rhyolite, dacite, andesite, trachyandesite, basaltic trachyandesite, basalts and lamprophyres e.g. [9][10][11][12][13][14][15][16]. In the area, the volcanism also leads to the development of some economic mineralizations, such as Doğanbey Cu-Mo porphyry and Inlice Au epithermal deposits [17][18].…”

Around İnlice village (WSW of Konya), numerous volcanic plugs crop out as steep-sided conical hills within Neogene lava dome covered partially by nuée ardente deposits. Nine circular to ellipsoidal plugs have determined with heights ranging from a few meters to >50 meters, and hence creates usually visible topographic landscapes. Plug-4, tallest one, has a joint system developed typically in NE direction, which was cut by faults formed in N-S direction. In spite of the intensive alteration, mineralogical and petrographical characteristics of the samples suggests that the plugs are composed of dacite-andesite. The samples have also mafic enclave and some disequilibrium structures such as sieve texture in plagioclase, and acicular apatites, suggesting magma mixing and mingling in their petrogenesis.

“…According to Keller et al, (1977), volcanic activity in this area continued from the Late Miocene (11.9 Ma) to the Pliocene (3.35 Ma). A limited number of studies have been conducted on these volcanics around Konya (Ota and Dinçel, 1975;Keller et al, 1977;Ulu et al, 1994;Kurt et al, 2003;Koçak, 2012;Asan and Ertürk, 2013;Uyanık and Koçak, 2016;Koçak, 2017;Koçak, 2021). Petrological and geochemical data obtained from volcanic rocks provide information about the geodynamics of the study area.…”

The study area is located around the town of Hatunsaray, approximately 40 km away from the south-west of Konya. In this study, the petrological and geochemical characteristics of the Bulumya ignimbrite, Detse ignimbrite and Sadıklar ignimbrite observed in the region were revealed. The study area is basically Upper Miocene - Lower Pliocene aged Güneydere formation and overlying Bulumya ignimbrite, Detse ignimbrite, Sadıklar ignimbrite and Quaternary alluviums. All these units were formed in the Upper Miocene - Lower Pliocene aged fluvial and lake environment and have a lateral vertical transition with carbonate, clastic units. The gray colored Bulumya ignimbrite contains andesite-dacite rock fragments and large pumice grains. The Detse Ignimbrite is yellow in color and shows a well sorted lapilli tuff composition. The Sadıklar Ignimbrite, on the other hand, contains agglomeratic levels with yellow colored slightly fused lenses and wedge geometry. All ignimbrite samples have porphyric texture and were classified as “crystal-vitric tuff” and “crystal lithic-vitric tuff” in the glass-crystal-rock fragment classification. In petrographic investigations of ignimbrites, general mineral paragenesis consists of quartz, plagioclase, plagioclase microliths, biotite, amphibole, opaque minerals and rock fragments. When geochemical data are evaluated, it is observed that all ignimbrite samples are subalkaline, trachy-andesite, andesite-basaltic andesite and calc-alkaline in character. When the main oxide, trace and rare earth elements are evaluated, fractional crystallization is observed in ignimbrites mainly controlled by K-feldspar and plagioclase minerals. In addition, the high K and Rb content in the spider diagrams indicate crustal contamination. The distribution of the ignimbrite samples in the Rb/Y-Nb/Y diagram suggests that the magma source forming the samples is enriched by subduction and/or crustal components.
