KGS--Kansas Rocks and Minerals--Kansas Rocks
The only metamorphic quartzite known in Kansas is located in Woodson County, four miles west and 10 1/2 miles south of Yates Center and is probably associated with an intrusion of igneous rock in that area. The quartzite of Woodson County is a thin-bedded, slabby, hard rock of many different colors-green, gray, pink, and black.
