Abstract :

Binalud Mountains are defined as a transitional zone between Central Iran and Alborz Mountains. It has a fairly thick sequence of sedimentary, metamorphic and plutonic rocks. The oldest deposits belong to Silurian age. In this paper Rhaetian Early Liassic deposits are studied which has more than 2000 m thickness. They are mostly included of phylitte, slate, sandstone, quartzite and thin-bedded limestones which is called as "Mashhad Phyllites". In the study of 1:100000 map of Torghabeh several macrofossil are collected. Four plant macrofossil species are identified. They are Clathropteris platyphlla, Clathropteris sp., Thaurnatopteris sp. and Otozamites sp. According to their stratigraphical distribution Rhaetian -
Early Liassic age can be suggested for this assemblage.
Key Words: Binalud, Mashhad Phyllites, Rhaetian- Early Lias, Plant macrofossil.
