Study Economic Geology of Copper Deposit North West Chah Galeh Toroud Semnan

Study area semnan province and south- south east damghan located details of mining area and is metallogenic toroud. Mining area toroud in the northern part of central iran zone outcrops Precambrian rocks to sediment all testament view is. Rocks area oldest attributed to Precambrian been including set of gneiss, Amphibolites, and schist. There is copper mineralization range chah galeh within rocks traky andesite as a vein with copper trend east- west during streak 1200 meter and mining vein of grade two parts, high grade and low grade classification. Thickness average section high grade 40 cm and section low grade 100 cm. average grade copper at high grade section about 3.1 percent and low grade section 0.2 percent has been determined. Rate save copper ore high grade section 26 thousand ton and low grade section 65 thousand ton is estimated. Based on studies, origin chah galeh deposit hydro thermal solutions low temperature is, from volcanic rocks andesitic type and traky andesite origin have been.
