In this region Mn mineralization is sparse and rather extensive. Mineralization has originated from hot springs and precipitated on the earth surface. The mineralization is mainly massive and vein form. Due to the presence of hot springs and their traces in the study area, it can be concluded that Fe and Mn components were in the hot springs as solution and precipitated on the earth surface or penetrated into existing fractures and faults of the region by the hot springs and consequently caused the mineralization. The main Mn minerals are pyrolusite and psylomelane accompanied by gypsum, travertine, barite and jasper UR - http://www.gsjournal.ir/article_58434.html L1 - http://www.gsjournal.ir/article_58434_1af2d38646e284baa38995bdc686defa.pdf ER -
