Locality: Long Lake Zinc Mine (Richardson Zinc Mine; Lynx Mine), Olden Township, Frontenac County, Ontario, Canada (See on Mindat)
Size: 10.5 x 5.5 x 16.2 cm
Description:
Shown here is a nice specimen of fluorescent calcitic marble from this well-known Canadian locale. The most abundant mineral is the red fluorescing calcite; generous amounts of yellow fluorescing chondrodite (some say it is apparently humite) and greenish-blue fluorescing diopside are present; and nice "lightning bolts" of bright blueish-white fluorescing aragonite make this specimen even better. While it is not the best material that came out of this occurrence, this is still a nice cabinet-sized specimen.
I collected it in 2019, during a trip organized by the UV Nomads. It was one of my best finds.
