I found this in the Texas Hill Country in a dry creek bed, about 4 miles south of Utopia, Tx. I included a picture of the area in which it was found in case it might lend some clues as to it’s identity. This is the only piece like this that I found. This area is mostly limestone I believe. This sample is not wet- it has a “sheen” to it when rotated. Anyhow, can anyone help? (Sorry if the pics don’t post or come out sideways... I’m still learning all this internet stuff)
hmmmm... my guess is Calcite or Microcline.
Always hard to tell just from pics, but I have to agree with Swizz....looks like a cool piece of Microcline!
My guess is calcite (the main mineral in limestone)
Looks like weathered calcite crystals, or a calcite formation that replaced a fossil (like coral).
