Abstract

To understand magmatic activities of Arhavi region the area must be considered in the context of geolgical evolution, of East Pontide Orogenic Belt as a whole from the North to the South as follows a) The Volcanic sedimentery rocks b)Intrusive rocks c)Ophiolitic rocks. In Arhavi region the units starts with the dacitic formation.Dacitic formation is comfortable overlain by Basic Volcanic Sedimentary formation. The basic formation has been concordantly overlane by Volcanic Sedimentery Rhyodacitic formation. During Maestrichtian-Paleocene in the existed geosynciine Flysch Sediments were deposited.Alpine orogenic activity is characterized by fresh andesites and bazalts.The rock samples collected in Arhavi vicinity were analyzed chemically and determined values plotted into geochemical disciriminant diagrams.They mostly show a calc-alkaline affinity with subordinate tholeitic and minor alkaline character. Their petrological characteristics indicate that they have been formed by continental rifting due to tensional forces acting on this sector of the Western Anatolia.

Özet

Bir bütün olarak Arhavi bölgesinin magmatik faaliyetlerini anlamak için bölge Pontid Orojenik Kuşağı çerçevesinde ele alınmalıdır. Kuzeyden güneye, a- Volkanik sedimenter kayalar, b-Sokulum kayaları c-Ofiyolitik kayalar Arhavi bölgesinde stratigrafik birimler dasitik formasyonla başlar. Bu formasyon bazik volkanik sedimenter formasyonla üzerlenir. Bu formasyonun üzerine volkanik sedimenter riyodasitik formasyon gelir. Mestriştiyen-Paleosen boyunca çökelen filiş sedimentleri bu birimleri örter. Tersiyer magmatizması genç bazalt ve andezitleri meydana getirmiştir. Toplanan kaya numuneleri kimyasal analiz değerleri jeokimyasal değişim diyagramlarına yerleştirilmiştir. Çoğunun kalkalkalin tali kısmının toleytik çok az, bir kısmının ise alkali alana düştüğü görülmüştür. Petrolojik özellikleri göz önüne alındığında, volkanizmanın bölgede etkin olan tansiyon rejimi sonucu oluşan kıtasal riftleşme ürünü olarak meydana geldiği düşünülmektedir.
