Uraninite Crystal on Titanite (Sphene) Crystal - Albion Lake, Bancroft, Ontario, Canada

UO₂

CaTi(SiO₄)O

Here's something you don't see every day. Uraninite crystals growing on other crystals. I picked these up from an old collector, and in all my years of collecting U & Th minerals, I don't think I've ever come across specimens like this before. I only have a couple, go get one while you can.

Here we have a little a pyramidal crystal of Uraninite on a larger crystal of Titanite (Sphene) from Albion Lake, Bancroft, Ontario, Canada. This specimen comes in at approx 3000 cpm on an SE International Ranger EXP.
