Here, the rarely represented whitish scapolite containing marialite component, locally also dravite, may be indicative of evaporite components in metasedimentary protolith and/or hydrothermal activity (Kadounova, 1987; Kfibek, 1988; Kfibek et al., 1997; Kfiz, 2009).
Associated minerals are: chlorapatite, almandine, diopside, enstatite, chlorian biotite, potassic pargasite, marialite and plagioclase.
Scapolite of undetermined composition (meionite or marialite) was observed as small anhedral grains in gray-colored bands consisting of quartz, calcite, fine-grained grossular and subordinate wollastonite.
