Grey rhombs of dolomite that fluoresce white are perched on the tips of kutnohorite sprays. Red fluorescing calcite present in the matrix. Patchy yellow fluorescence is probably cerussite. Specimen measures 80x65x10mm.
Cream kutnohorite with pyrite on a quartz matrix. Width of view 6mm. Stack of 30 images. Click on the image below for a higher resolution version.
Groups of typical kutnohorite with quartz and a little pyrite, all on a matrix of pale pink fluorescent manganoan calcite. Specimen measures 60x40x20mm.
Quartz crystals and a couple of fluorescent red calcite crystals on a spray of kutnohorite. There are pyrite crystals included in the quartz, as well as on the quartz and on the kutnohorite, some of...
A mushroom of kutnohorite altering to rhodochrosite. Three views of the one specimen. Width of specimen 22mm.
Pale crystals of kutnohorite on quartz with pyrite, all on a bed of fluorescent Mn-calcite. Specimen measures 4×5.5cm. Ex W.F. Davidson Collection. Ex Ralph Merrill Collection. Close up photo: Width of view 6mm. Stack of...
Pink drusy crystals of rhodochrosite coating acicular kutnohorite and white calcite that fluoresces red. 40x36x33mm.
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.
