Abstract
The identified mineral association in the crystalline limestones from the manganese locality Čučma - Čierna baňa consists of garnets and pyroxenes. Mineralogical composition of the samples Ču-1 and Ču-2 is represented by zonal garnets with Grs76.12-82.31; Adr17.69-23.88 composition in the core and Grs95.48-97.05; Adr2.95-4.52 composition in the rim. In the sample Ču-3 inverse zonality (the core Adr3.99, Grs96.01; the rim Adr20.55, Grs79.45) of garnet is observable. The analyzed pyroxenes have a diopside composition with a variable Mg/(Mg+Fe2+) ratio. A slightly increased content of Mn (up to 0.09 apfu) ascends into the johannsenite molecule.
期刊介绍：
Bulletin Mineralogie Petrologie is a peer-reviewed journal focused especially on: mineralogy, crystal chemistry and study of crystal structures of minerals study of mineral associations and processes of their origin meteoritics, research of tectites economic geology (of ore deposits) and study of history of mining of ore deposits topographic mineralogy petrology of igneous, metamorphic and sedimentary rocks instrumental analytical methods at mineralogy and petrology mineralogy and petrology as tools for archeology and similar disciplines
