Tradename of syenite clasts containing fluorescent sodalite found in 2018 by Erik Rintamaki, a mineral dealer, on the beaches of Lake Superior, Michigan, USA.

Rintamaki self-named the rocks Yooperlites in honor of the endearing nickname Yooper for people who live in Michigan's Upper Peninsula.

The scientists believe the Yooperlites are not native to Michigan but were originally sourced from the Coldwell Alkaline Complex in Ontario, Canada. The Yooperlites were then likely transported south via continental glaciation and made their way into Lake Superior.
