Resumo

The Ziyaran Volcanic Belt (ZVB) is located in the southern part of central Alborz and in the Ziyaran area. The geology of this layer includes various kinds of stone units. In the north, they are the reminder of Cenozoic, quaternary deposits, and in the western part, the exposure stone units are mostly Precambrian and Paleozoic deposits and in the south-eastern part of the studied area, the stones belong to the Mesozoic era and specifically, the sediments belong to the Jurassic era are exposed. Also, the basic volcanic rocks that belong to the Eocene period are located in the Ziyaran area, in the western part of Taleqan County and in the Alborz state. This study aimed to evaluate the petrology of Ziyaran Volcanic Belt (ZVB) Eocene volcanic rocks. For this purpose, which is mostly focused on the study of Cretaceous stones in the central Alborz zone, sampling of the stones in the intended area was performed with the survey and field methods and for 120 samples. After the preparation of the thin layer from the well and without alteration samples, they were examined with petrography and petrology tests. The results of the petrology studies of the volcanic rocks of the Ziyaran area expressed that the basic volcanic rocks in the intermediate area with the intermediate- upper chemical composition of Eocene Alkaline Phosphatase (ALP) located in the central zone of Alborz heights, with lithology composition of Alkali olivine basalts and Andesite.
