Abstract :

The studied area is located 35 Km of north of Kashmar. According to the tectonical-sedimentary division of Iran, this area is belongs to northeast of central Iran.
Petrologic components of volcanic rocks in this area involved andesite to dacite and plutonic rocks in this area including difference types of diorite-monzodiorite and gabbro-gabbrodiorite and granodioritic rocks in a small outcrop.
According to the major oxides and rare earth elements diagrams, crystal diffraction is a main rocks forming process in this area, so magma type is Calcoalkaline and is related to continental margin. According to the geochemical diagrams and REE ratio, andesitic rocks belong to Andian type.
In this area, we can see metal and metalloid ore as a result of post volcanic process.
On the basis of calculated correlated matrix of this elements in water samples, the relationship between volcanism and mineralization has been identified. The mineralization can affect on water pollution.
In this study, with the help of piper and stiffs diagrams and quantities indexes, it was concluded that lithological variation affect water quality. Based on the environmental evaluation in this area, most of water sample are contaminated.
