Medium-grained granites from the Llano Uplift of Central Texas

On the left is a medium-grained gray granite for which my notes are missing.

On the lower right is a tourmaline-bearing white granite. It's from a quarry that forms a hazard on a par 3 hole at the Llano Municipal Golf Course.

On the upper right is a reddish medium-grained granite from the Wolf Mtn. Scout Ranch, northwest of the town of Llano.
