Tremolite marbles represent a specific lithotype of marbles in some crystalline complexes situated particularly along eastern margin of the Bohemian Massif. marbles from the Olešnice Group are good example for the study of metamorphic reactions producing tremolite. Using transmitted light and CL, several mineral reactions producing early tremolite I (Tr I) were found:olite marbles form relatively thin layers (up to 1 m thick) within large metacarbonate bodies or small individual lenses (up to 10 m thick) located in mica schists. Two distinct compositional types were recognized, calcite- and less abundant dolomite-dominant marbles, respectively. The typical mineral assemblages: Cal + Tr  Phl and Dol + Cal + Tr  Phl mostly exhibit Tr >> Phl, but locally Tr < Phl.
