Abstract
Kaolin deposit of Heshmat Abad in south Rudbar, is situated in Alborz zone. This deposit is like an alteration zone with thickness of 10 meters which has a fault zone outcrop trending the northwest-southwest. Based on petrographical studies the host rock contains vitric Tuff crystal mineralization with rhyolitic composition which belongs to the middle Eocene. Kaolin is created due to alteration of glass tuff argillic which is witnessed in two consecutive generations: first generation made by alteration of feldspar crystals in host rock and second generation fills the seams of the rock in form of veinlets and veins. Based on deposit studies, the main mineral phases include quartz, kaolinite and nacrite. Chemical studies showed that the deposit of Heshmat Abad is very similar to the deposit of Sabzevar and Zonuz. Considering the results of strength raw test of area samples, Kaolin from this mine can be used as a filling industrial soil in the body formula of ceramic tiles.
