پيدايش مرمرهاي بروسيت، سرپانتين فرستريت و هيدرومنيزيت دار در شرق شيركوه يزد

Occurences of Brucite, Serpentine, Forsterite and Hydromagnesite Bearing Marbles, East of Shirkuh, Yazd

Due to post Cretaceus intrusions, various marble-skarn mineralization are formed in eastern Shirkuh Fault Zone. Marbles constitute the last zone in cantact metamorphic aureole. Marbles are characterized by following mineral assemblages: brucite+serpentine+forstrite+hydromagnesite+calcite+dolomite. The marbles are undergone to pyroxene hornfels facies with the temperature between 450 c to 600 c (p<2kb). The study has shown the paragenesis and texture relation of minerals as well as the three stages of decarbonation, hydration and carbonatio
