found these about 7 miles from campsite, not certain if these are from a meteorite or volcano tubes(worms, as they are called by some)....just something differnet to talk about, it looked like a burnt rock site at first is why we checked it out

You saved all those "rocks " ??

Bottom left is Markasite. All the rest, a geologists dream

Sh.....why are the "other ones" a geologists dream? they look like rusted glass to me but some of them do have some tiny little crytals on them and they stick to a magnet. Is the Markasite from the central Texas area?
We found all of these here in Gaines,Co.
Would you send any of these in for analysis?

SANDY, really they stick to a mag nut? meteorites do too!

there is no doubt if thet are magnetic send them in

A dream because of their mineral content and what gave them a "tube form" AND MAGNETIC
It's bound to be an iron sulfide, I found some around Amistad in Gypsum deposits that look similar in texture & color, globular not tubular but never magnetic...

Just mail one representative piece to the university of your choice ( geology dept )

Google Markasite

will send a sample in after the first....our metal detector goes off like crazy but does not show any "type" of metal.

SH.hubby says if you like studying minerals or rocks , as such, he will send you a piece of it if you want one...send me an email with an addy if you want to and but it will be after the 3rd before I send it. We only have a 30 X magnifying glass to look at it with. so just let me know if yu want a piece of it. we enjoy looking at the little minerals on it.

No thanks S,Not for me, I have a whole back yard littered with neat finds I have drug home
Just get that one sample off to the university.
