Pink rhodochrosite with small white crystals (kutnohorite?). These white crystals are also included in the quartz. Ex Barry Johnson Collection. Video best viewed full screen.
A mixture of Mn-rich calcite-Ca-rich rhodochrosite pseudomorphing kutnohorite, sitting on drusy quartz crystals. According to Ralph Bottrill, analyses showed Mn40Ca60 and Mn75Ca25 from XRD. This specimen is quite pale compared to others found on a field trip...
A couple of very sharp analcime crystals nestled amongst pale pink kutnohorite from the Emilie Mine (Bülten-Adenstedt Mine), Peine, Lower Saxony, Germany. It’s nice to see zeolites in unusual combinations.
