Repost: 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:

Le #niobium est l'exemple même de ces minerais "critiques" réputés nécessaires pour la transition énergétique
Mais à y regarder de plus près, il sert surtout pour faire rouler des #SUV et lancer des missiles made in USA

As an example of the changes happening in the stratosphere, #Niobium and #hafnium do not occur naturally. Yet these metals, along with other distinct elements from #spacecraft, were embedded within roughly 10 percent of the most common particles in the #stratosphere.
