Mystery mineral from Marathon, TX

by Susan L Dunlap
(Fort Worth, TX)

I found this while rockhouding outside of Marathon, TX on a pay dig. The piece seems to be growing around the darker stone and has a smooth, pebbly texture. It seems to cast a blueish to purpleish color. I’ve never seen anything like it and am hoping someone can help me identify what it is.

Idon't know what this is. It looks like multiple layers . Something wrapped in something else and all of that wrapped in what appears to be agate.

If you have a college or university nearby you could take it to their geology dept.

Your local gem and mineral club may also be helpful with identification.
