Rhodochrosite:  MnCO3.

Named in 1813 by Johann Friedrich Ludwig Hausmann from the Greek “rose”, and “colouring”, referring to its colour.
Calcite Group.  Calcite Rhodochrosite Series and Rhodochrosite Siderite Series.  Commonly occurs as a primary gangue mineral in moderate to low temperature hydrothermal veins.  Also in high temperature metasomatic deposits and sedimentary manganese deposits or as a late stage hydrothermal mineral in pegmatites, especially lithiophilite bearing ones.

Magnetite: Fe2+Fe23+O4.

Originally called lodestone as early as 1548 and by other names.  Named in 1845 by Wilhelm Karl von Haidinger for the locality at Magnesia, Greece (site for lodestone).   Spinel Group, Jacobsite Magnetite Series.  Magnesioferrite Magnetite Series.   Magnetite is an important iron ore, along with hematite.  Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian.
