With #kyanite I always remember this video created by Stacey Phillips via the Mineralogical Society (the LEGO stop motion science videos) -

Quebec has industrial quantities of kyanite -although I don't think any are being mined today. They're in the Grenville, the roots of the Himalayan-scale mountains formed over a billion years ago. The screenshot below is from MinDat: https://www.mindat.org/locentries.php?p=14009&m=2303
The Ministère has an awkwardly translated page "Mineral Substances in Quebec" that includes Kyanite in its list of wealth:

Perovskite is found just west of Montreal in the Oka Complex; Carbonate-rich, silica-poor magma emplaced in the Cretaceous. The site was mined for niobium in the 1960's and 1970's -it's also enriched in REEs and thorium.
There’s more about perovsite at Oka on MinDat:

Kyanite isn't just a fetching blue mineral that documents the experience of sediments under extreme duress.
It's an ore -Virginia alone mined 83,000 tonnes in 2023. Kyanite in furnace insulation transforms to mullite when heated, expanding to reduce porosity and shrinkage.Virginia Kyanite (photo: J. Wyman) from:

Antimony Tin Oxide scatters the wavelengths of infrared light emitted by warm humans. The antimony is often sourced from #stibnite. This material is being used to create fabric infrared invisibility cloaks!

from the Rocky Mountain Association of Geologists:
Titanite: the Wedge-shaped Timepiece, by Ronald L. Parker#Titanite has a distinctive crystal form that it flaunts…
…titanite is among the very few minerals that enjoy a larger color dispersion than that of diamond…
Hayden, Watson & Wark established that the relative concentration of Zr 4+ in titanite is systematically related to pressure and temperature conditions.

A titanite lozenge imaged both using a cellphone through the microscope ocular, and with a proper imaging system. It's surrounded mostly by quartz (+feldspar).
Likely from the Grenville, but from a teaching collection two generations of retired professors ago.
