Abstract :

The study area is located in North Khorasan , 50 Km southwest Bojnord and northeast Sankhast. MILA FM,s lime, Cambrian siltstone and gray shale with GHELLI FM, s shale and green sandstone accompanied basalt and andesitic basalt .existence of enormous thrust with E-W extension cause lime lie in top of shale and sandstone. Andesit and andesitic basalt contact is thrust. Two magnetite outcrop is found in near GHELLI VALLY , they have a extension like thrust. Number 15 stream sediment selected of major waterway that cross basalt and andesitic basalt rocks and analysed for Ag , Cu , Mn , Fe , Pb , Zn .maximum value of results show in below:
Fe = 6 % ، Mn = 1000 ppm ، Ag <1 ppm ، Cu = 38 ppm ، Pb = 44.5 ppm ، Zn = 185.6 ppm
Analytical results show us anomalies of Pb & Zn that intercommunicate basalt and andesitic basalt rocks.
