Igneous bodies in Manshad-Taft fau lt
zone arc intruded into Shirkuh granitic batllolilic
basement. They also cause different skam-marble
mineralization in dolomitized limestones which are
covered granitic basement. Skarns are composed of
variety of minerals. Marbles consist of variolls
minera ls such as brucite, forste rite, diopsid,
pcriclase,taJc, calcite, dolomite, and hydromagnesite.
Petrographic and geochemical data have revealed
tbat there is several stages duri ng the formation of
marble minerals. At the first stage, anhydrous
minera ls fonned, then fo llowed byhydrous
assemblage. Generation of brucite occurs at the
second stage and is due to latc hydrothermal system
withlow XCOl and high nuids.
Hydromagnesite deposition is occurcd by oxidation
of bruc ite.
