Abstract
New data on the composition and structure of zoisite from the area of Dvuglav Peak in the Rila Mountain have been obtained using modern methods and equipment. Chemical analyses data show the presence of different impurities that can replace Ca and Al in the structure of the mineral. The presence of Mn as a chromatophore in thulite is confirmed. The characteristic interplanar distances and Raman shifts for the specimens are recorded and tabulated. They are compared with the already known ones in the literature and databases. Due to the similarity in both the composition and the structure of zoisite and lawsonite, an analogy is also observed in their Raman elastic moduli.
