The occurrence of health-relevant contaminants in water has become a severe global problem. For treating heavy-metal-polluted water, the use zeolite materials been extended over last decades, due to their excellent features high ion exchange capacity and absorbency. aim this study was assess effect heavy metal uptake one purified (PCT) two non-purified clinoptilolite tuffs (NPCT1 NPCT2) aqueous...

hydrothermal alteration processes are extensively took place on volcanic and pyroclstics of takestan area. existence of abundant, deep fracturing and subvolcanic intrusions are enhanced extend hydrothermal alteration zones. the following alteration zones are determined: propylitic, argillic, advanced argillic and sillicic. there are outcropped and widespread in different size and limit. formati...

Massive Zn-Cu-Fe sulfide deposits at the Garon Lake Mine occur in three sulfide lenses in a group of metamorphosed rhyolite crystal tuffs, metasediments and basalts. The major ore minerals are sphalerite, chalcopyrite, pyrrhotite and pyrite. Minor associated silicates are actinolite, tremolite, chlorite, albite and quartz. Rounded detrital pyrite, magnetite and chert grains and diagenetic p...
