摘要
In north region of Mud city, southeast of Birjand – central east of Iran, in the position of 59/37 east longitude and 32/50 north latitude, we have some outcrops of relatively fresh basic volcanic rocks. They seem to be young and they mentioned Quaternary volcanic lavas in related geological map. According some signs such zoning in Olivine phenocrysts, absence of alteration signs in olivine phenocrysts rims and relatively low value of plagioclase in the composition of rocks, we propose that their volcanic nature is alkaline. This fact that they have erupted as the result of right lateral deep fault zones, also reinforce our Idea. In the area we see this structural architector as the results of major Nehbandan fault system behavior.
