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 phyllite, slate, sandstone, quartzite and thin-bedded limestones which is called as "Mashhad Phyllites". In the study of 1:l00000 map of Torghabeh several macrofossils are collected. Four plant macrofossil species are identified. They are Clathropteris platyphylla, Clathropteris sp., Thaumatopteris sp. and Otozamites sp.. According to their stratigraphical distribution Rhaetian- Early Liassic age can be suggested for this assemblage.
