„Discovering Yooperlites: The Glowing Rocks of Michigan’s Upper Peninsula”

Yooperlity, also known as Glowdalite, are Sodalite-Syenite rocks containing fluorescent Sodalite. They were discovered by Erik Rintamaki along the shores of Lake Superior in the Upper Peninsula of Michigan. Rintamaki named them Yooperlites, from „Yooper” – a term for residents of the Upper Peninsula of Michigan, and „lite” to describe their fluorescent quality. These rocks are predominantly found in the Upper Peninsula of Michigan, particularly in Keweenaw County, due to the unique geology of the area. Under normal light, they appear completely ordinary, but they glow when exposed to certain lengths of high-energy ultraviolet light. Michigan Tech University conducted research on these rocks, revealing that their composition includes sodium, aluminum, silicon, chlorine, and oxygen, but lacks structural sulfur, which is likely responsible for their fluorescent glow.

„The Geological Mystery of Yooperlites Unearthed: A Rare Sodalite-Rich Rock Formation Revealed by Glaciers”

Yooperlites formed about 1.1 billion years ago during volcanic eruptions and lava flows within the Mid-Continent Rift below Lake Superior. As the magma solidified, it transformed into a sodalite-rich rock called syenite, similar to granite. These rocks remained hidden until the last glaciation, about 100,000 years ago, when massive glaciers exposed the Earth’s surface, revealing them. The glaciers then transported these rocks across the landscape of the Upper Peninsula of Michigan and the Great Lakes region.
