Özet:

 Karahallı basin is located in the northwest of the NE-SW trending Çivril-Baklan Graben in Western Anatolia. It is aimed to examine the mineralogical and geochemical properties of the buried Plio-Pleistocene aged units identified for the first time in the study area where tectonic activity is actively observed and to reveal the tectono-sedimentary development of the basin. 10 deep drilling logs were used and correlated with each other besides field observations. In drillings with depths ranging from 342 m to 670 m, fluvial and lacustrine units with a thickness of hundreds of meters have been cut. Fluvial sediments consist of clastic units such as weakly consolidated conglomerate, locally cross-layered sandstone, mudstone and siltstone. Lacustrine sediments commonly consist of calcareous, fossiliferous mudstone containing organic material, clayey limestone, limestone, claystone, marl, coal and travertine. It has been determined that the Karahallı basin is a lake basin that is constantly fed by rivers and gets deeper towards the west and northeast. Calcite, dolomite, anhydrite, gypsum, feldspar, quartz and clay minerals were determined in the examined samples by XRD analysis. Travertine and limestone are mainly composed of calcite minerals; marl, mudstone and clayey limestone contain clay, calcite and dolomite. From the clay minerals, Mg-smectite, Na-smectite, illite and kaolinite were detected. In SEM studies, smectite showed typical honeycomb and cornflake morphology. Small, poorly developed rhombohedric calcite and dolomite crystals are observed. According to geochemical analysis results, it was determined that the rocks originate from the same origin and commonly consist of units with acidic composition.

 Karahallı havzası Batı Anadolu da KD-GB uzanımlı Çivril-Baklan Grabeninin kuzeybatısında bulunur. Tektonik aktivitenin etkin olarak gözlendiği çalışma alanında ilk kez tanımlanan gömülü Pliyo-Pleistosen yaşlı birimlerin mineralojik, jeokimyasal özelliklerinin incelenmesi ve havzanın tektono-sedimanter gelişimininin ortaya konulması amaçlanmıştır. Çalışma amacı kapsamında, arazi çalışmalarıyla birlikte 10 adet derin sondaj logu kullanılmış ve birbirleriyle korele edilmiştir. Derinliği 342 m ile 670 m arasında değişen sondajlarda yüzlerce metre kalınlığa sahip fluviyal ve gölsel birimler kesilmiştir. Fluviyal birimler zayıf pekişmiş çakıltaşı, yer yer çapraz tabakalı kumtaşı, silttaşı ve çamurtaşı gibi kırıntılı birimlerden oluşmaktadır. Gölsel tortullar yaygın olarak, fosilli, organik malzeme içeren kalkerli çamurtaşı, kiltaşı, killi kireçtaşı, kireçtaşı, marn, kömür ve travertenlerden oluşmaktadır. Karahallı havzasının akarsular tarafından sürekli olarak beslendiği ve batıya ve kuzeydoğuya doğru giderek derinleşen bir göl havzası olduğu belirlenmiştir. İncelenen örneklerde XRD analizleri ile kil mineralleri, kalsit, dolomit, feldispat, kuvars, jips ve anhidrit belirlenmiştir. Traverten ve kireçtaşlarının başlıca kalsit mineralinden oluştuğu; marn, çamurtaşı ve killi kireçtaşların da ise kil, kalsit ve dolomit mineralinin bulunduğu belirlenmiştir. Kil minerallerinin analizi ile Mg-simektit, Na-simektit, illit ve kaolinit tespit edilmiştir. SEM çalışmalarında simektit tipik bal peteği ve mısır gevreği morfoloji göstermiştir. Küçük, iyi gelişmemiş romboedrik kalsit ve dolomit kristalleri gözlenmiştir. Jeokimyasal analiz sonuçları değerlendirildiğinde kayaçların aynı kökenden kaynaklandığı ve yaygın olarak asidik bileşimli birimlerden oluştuğu belirlenmiştir.
