Agate Photos by Tom Noe
Structures 179
This is one of the most complicated agates I've ever seen. See the three intrusions of matrix? The left one and the middle one are the same. The right one is a different composition and grain structure. Shards of broken agate are encircled by matrix in several places. The middle area of matrix looks like it squished the agate bands on the left side of it but fractured the agate bands on the right of it. Lots of questions here.
