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.

Čučma-Čierna bańa（斯洛伐克共和国）结晶石灰中的Grosoular和透辉石

在锰产地的结晶灰岩中发现的矿物组合为石榴石和辉石Čučma - Čierna baňa。样品Ču-1和Ču-2的矿物组成为带状石榴石，grs76.12 ~ 82.31;核心成分adr17.69 ~ 23.88, grs95.48 ~ 97.05;Adr2.95-4.52成分在边缘。样本中Ču-3逆地带性(核心Adr3.99, Grs96.01;石榴石边缘Adr20.55, Grs79.45)可见。所分析的辉石具有可变Mg/(Mg+Fe2+)比的透辉石成分。锰含量略有增加(高达0.09 apfu)上升到约翰长石分子中。
