Day #82 Deskcrop: Wausau Syenite

We’ll stay in Wisconsin for today’s deskcrop – the ~1520 Ma Wausau syenite. This deskcrop comes from an outcrop in the back of the parking lot of the Wausau Insurance Company, and it’s as nice and pristine a syenite as you could hope to collect. This one’s probably quartz normative but there’s no macroscopic quartz to be seen.
