Abstract :

The study area is located in northwest of Anabad city of Khorasan Razavi province. Region geology is consisting of Taknar formation (Chlorite sericite schist, Sericite schist and Meta gabbro-diorite), Precamberian intrusive rocks and colour mélange. Three types of mineralization is recognized: mineralization in Taknar formation, mineralization in granitoids as disseminated and vein type mineralization. Mineralization is in Taknar formation unites as disseminated pyrite and pyrite veinlets. Also, in granitoid rocks is form disseminated pyrite.
Mineralization is in vein type consists of pyrite and specularite. According to results of stream sediment geochemistry, we have anomaly of gold (22 ppb), silver (97 ppb), zinc (177.7 ppm), and lead (95.9 ppm) elements. In lithogeochemistry samples, maximum anomaly of lead, zinc and silver elements are in order of 2630.81 ppm, 2153.8 ppm, and 3378 ppb. The high anomaly is related to taken samples from silicified - iron oxide zone in Meta quartz monzonite porphyry.
