Re: Ooops!
Mon, October 12, 2009 - 1:37 PMHello. BJ. That stone I happen to recognize right away as an agate.
The story is actually in the stone. It's got large pieces of material also that have been changed to a quartz composition from what I'm thinking is an original limestone, composed of pebbles of stone (geologists might call them 'rip-up clasts') in a matrix of little balls called 'ooids'. The way it's been agatized is pervasive, but not destructive, and that's an entire story in itself, as agatization/silicification is kind to the original depositional texture of a sedimentary rock.
Congratulations on your acquisitions. -

Mon, October 12, 2009 - 3:44 PMThank you for your suggestion! I'm going to go with Agate but maybe I can find a photo of an Agate Jasper and compare.

Mon, October 12, 2009 - 4:08 PMAgate is banded and jasper is opaque, both are types of non crystallized quartz.
