this is mica. wash it to clean off the mud. hit it with a tooth brush. you will notice that thin layers of mica will come off. These will show two directional perfect cleavage. Very diagnostic for mica. Do not soak in water only wash. soaking mica in water can ruin a good specimen

Mica was mined in them-thar-mountains. Look up 'mica books' azdif. i believe the 'books' came in hex shapes. It was used for high-temp furnace windows and old timey vacuum tubes. Welcome to the forum.
