İnceleme alanı, Orta Torosların jeolojik özelliklerini içermekle birlikte, Aladağ Birliği, Bolkar Dağı Birliği ve Bozkır Birliği adlarıyla bilinen ve yapısal, stratigrafi ve metamorfizma özellikleri bakımından birbirinden ayrı ortam koşullarını yansıtan kayaç birimi toplulukları aralarında tektonik dokanaklı olarak birbirleri üzerinde yer almaktadır. Bolkar Dağı ve Aladağ birlikleri, Geç Devoniyen-Geç Kretase yaş aralığında çökelmiş olan şelf tipi karbonat ile kırıntılı kaya birimlerini içermektedir. İçerisinde Senoniyen yaşlı olistolit ve olistostromal bloklar bulunmakla birlikte, tamamı inceleme alanında gözlemlenmeyen Geyik dağı birliğine ait olan Lütesiyen yaşlı denizel kırıntılıların üzerinde çok düşük açılı naplar halinde üzerlemektedir. Bu iki tektonik birlik, birbirleriyle benzerlik göstermekle birlikte hem stratigrafik hem yapısal hem de metamorfizma özellikleri açısından farklıdırlar. Yamaç, havza ve az oranda platform çökelleri ile temsil edilen Bozkır Birliği, Triyas-Kretase aralığında bazik deniz altı volkanitleri, tüf, vb. kayaların değişik boyutlarda blok ve dilimleri kapsayan büyük bir melanj şeklindedir. Geç Paleosen- Erken Eosen yaş aralığında, Aladağ ve Geyik Dağı birliklerinin arasında ofiyolit, spilitik volkanit arakatkılı pelajik kireçtaşlarını kapsayan “Ofiyolitli Melanj” ile temsil edilen dar ve kısa ömürlü bir okyanus havzasının yer aldığı düşünülmektedir. Karışık, Geyik dağı birliği ile Aladağ ve Bolkar dağı birlikleri arasında, değişik kalınlıklarda naplar halinde bulunmaktadır. Birliklerin birbirleri ile stratigrafik, yapısal ve metamorfizma özelikleri dikkate alındığında (a) Erken Triyas-Senoniyen aralığında, güneyden kuzeye doğru Geyik dağı, Aladağ, Bolkar dağı ve Bozkır birliği şeklinde bir dizilimle, platformdan okyanusa uzanan bir havzayı oluşturdukları (b) Kuzey Tetis Okyanusu olarak adlandırılabilecek olan bu havzanın Geç Senoniyen’de kapanmasına bağlı olarak, Bozkır birliğinin kendi içinde dilimlenip, Bolkar dağı ve Aladağ birliklerini üzerlediği (c) İlerdiyen sonunda Bolkar dağı ve Aladağ birliklerin kapanan havzanın ofiyolitleriyle birlikte, üzerinde Bozkır Birliğinin dilimlerini de bulundurarak göreceli otokton olan Geyik dağı birliği üzerine tektonik olarak taşındığı düşünülmektedir.
The area of examination includes the geological characteristics of the Central Toros, but the rock unit communities, known as the Aladağ Union, the Bolkar Mountain Union and the Bozkır Union, which reflect the environmental conditions distinctly in terms of structural, stratigraphic and metamorphic characteristics, are tectonicly placed on each other. Bolkar Mountains and Aladağ units contain broken rock units with shelf-type carbonate that collapsed in the late Devoniyen-Late Cretaceous age range. Though there are Senonian old olistolites and olistostromal blocks, all of them belong to the Geyik mountain union, which is not observed in the field of study, Lütesiyen old marine crushes are overwhelmed in very low-angle spots. These two tectonic units are similar to each other, but differ in both strategographic and structural and metamorphic characteristics. Represented by the basin, basin and a small proportion of platform collapses, the Bosque Union, the basic submarine volcanoes in the Triyas-Kretase range, weapons, etc. It is in the form of a large melange that covers blocks and branches in different sizes of rocks. In the late Paleosen- Early Eosen age range, it is believed that there is a narrow and short-lived ocean swimming pool represented by the "Ofiyolithic Melanj" which covers the officolithic, spicytic volcano-covered pelagic squares between the Aladağ and Geyik Mountain units. The mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains of the mountains. Considering the strategic, structural and metamorphic characteristics of the unions with each other (a) in the early Trias-Senonian range, from the south to the north, with a sequence in the form of the Geyik mountain, Aladağ, Bolkar mountain and Bozkır unions, they form a pool stretching from the platform to the ocean (b) depending on the closure of this pool, which can be called the Northern Tetis Ocean in the Late Senonian, the Bozkır unions are divided within themselves, and the Bolkar mountain and Aladağ unions are crossed over (c) in the future, the Bolkar mountain and Aladağ unions, along with the offshore of the air closed by the offshore of the offshore of the offshore of the offshore of the offshore of the offshore of the offshore of the offshore of the offshore.
In the study area, which presents the geological features of the Central Taurides, rock unit assemblages known as Aladağ Unit, Bolkar Mountain Unit and Bozkır Unit, which reflect different environmental conditions in terms of stratigraphy, structural and metamorphism, has tectonic contact with each other. Aladağ and Bolkar Mountain units consist of mainly shelf type carbonate and clastic rock units, Senonian aged olistolith and olistostromal marine clastics deposited in the Late Devonian-Late Cretaceous range, and are located as horizontally nappes on the Lutetian marine clastics of which belong to the Geyik Dağı association, that whole part of it can not be seen in the area. These two tectonic units which have similar aspects, shows difference each other with their stratigraphy, metamorphism and structural properties. The Bozkır unit looks like various size of tectonic slices of a mega mélange comprising Triassic-Cretaceous age basin-slope and less platform sediments, basic submarine volcanics, tuff, diabase, serpentinite, etc. It has been thought that a narrow and short-lived oceanic basin were formed between Geyik dağı and Aladağ units represented by ophiolitic mélange including ophiolites, pelagic carbonates interbedded with syphilitic volcanics during Late Paleocene-early Eocene period. The mélange is seen as tectonic slices of varying different thicknesses between the Geyik dağı unit, the Bolkar dağı and the Aladağ tectonic units. Considering the structural, stratigraphic and metamorphism properties of the tectonic units with each other; (a) In the Early Triassic-Senonian range, from south to north, Geyik Mountain, Aladağ, Bolkar Mountain and Bozkır units formed a basin extending from the platform to the ocean; (b) related to the closing of the basin, which could be named as Northern Neo-Tethys ocean, during late Senonian, initially the Bozkır unit sliced and thrusted onto the Bolkardağı and Aladağ units; (c) It is thought that the Bolkar Mountain and Aladağ tectonic units were transported tectonically over the relatively autochthonous the Geyik Dağı unit, including the slices of the Bozkır Unit, together with the ophiolites of the basin that closed at the end of the İlerdian.
