HATAY BÖLGESİNDE ULTRABAZİK TEKTONİTLER VE TABAKALI PERİDOTİTLER

Hatay ilinde yapılan son araştırmalar bölgedeki ultramafiklerin çok kökenli bir kayaç grubundan meydana geldiklerini ortaya koymuştur. Bazik ve ultrabazik masiflerin genel bir sınıflandırılması yapılmış ve özellikleri mukayese edilerek Hatay ultramafiklerinin diğer oluşumlar içindeki yeri belirtilmiştir. Kızıldağ masifinin önemli kayaç tipleri, yapı ve dokuları, kapsadıkları filoniyen kayaçlar incelenmiştir. Ultrabazik tektonitler yer mantosundan gelmiş ekaylardır. Mineralojik bileşimleri, yapısal ve dokusal özellikleriyle belirgindirler. Tabakalı peridotitler ise tektonitlerin kısmî ergimesinden oluşan magmanın fraksiyonel kristalleşmesiyle meydana gelmişlerdir. Serpantinitler, her iki kayaç grubunun Alpin orojenezi sırasında hidratlaşması sonucu oluşmuşlardır.

ULTRABASIC TECTONITES AND LAYERED PERIDOTITES OF THE HATAY AREA (TURKEY)

In the light of our recent investigations we can distinguish two types of ultramafic rocks in the Hatay region: ultrabasic tectonites and ultrabasic cumulates. The purpose of this paper is to outline the Origin and the features of these rocks. Basic and ultrabasic complexes are classified according to their geological setting, mode of formation, mineralogical composition, structural and textural features, etc. The Hatay ultramafics belong to the Alpine type of ultrabasic complexes. The tectonites are characterized by the existence of foliation and lineation. The cumulates show magmatic layering. Both of these rocks are subjected to partial melting eventually giving rise to the Production of a basic magma. Serpentinization of these ultramafics has taken place during the Alpine orojenesis.
