Refference : The first international applied geological congress; Department of geology Islamic azad university- Mashhad Publishing Year : 2010 Abstract : The studied basalt rocks are located at Northeast of darrod city - Neyshabour Northeast of Iran and are bounded between longitudes of 59 8 to 59 16 East and latitude of 36 7 to 36 11 North. The age of these rocks is Silurian and they have a various petrographical component such as normal basalt, olivine- bearing basalt, trachy basalt, basaltic andesite, basaltic trachy andesite, dolerite. The geological map of Torghabeh reports these rocks as pillow lavas, but because the studied area is tectonised and these rocks are fragmented, pillow structures not found at the studied area. Since coral fossils in the carbonate- sand stone facies of the area belong to Devonian, it can be concluded that volcanic rocks erupted at a shallow water depth environment during Caledonian phase.
