Thomasclarkite-(Y) is a rare mineral which was known as UK-93 until 1997 when it was renamed in honour of Thomas H. Clark (1893–1996) McGill University professor. The mineral is one of many rare earth element minerals from Mont Saint-Hilaire. The only reported occurrence is in an alkalic pegmatite dike in an intrusive gabbro-nepheline syenite.
