Heavy Round Rocks from Llana Estacado - North Texas

[Swoodbyrne525]

First post!

On a trip to north Texas, we pulled over so I could collect some of the cool rusty red embankment sediment in a jar, and found this odd rock. It appears to be three distinct segments, and is much heavier than it looks. It's approximately 4x4" and nothing similar was found near it.

Those look like barite nodules to me, but I don't know much about the local geology in Llano, TX. Maybe someone else here can confirm

I feel they are Barite nodules as well based on the description of the weight. Gypsum would be light as would Selenite, those minerals also make a simular formation to the one you have in sands. A lot of Barite reacts to UV light, if you know someone who has a UV lamp or have one yourself give it a shot.
