Is there a piece of pet wood in that conglomerate (base of 2nd pic), or it just seems to be like it? Adrian I was curious about that too Adrian. Will be cutting more conglomerate from the same place. Watching closely for wood's, palms and mosses. And have more tumbles from the same rock you mentioned. It was a ~4 pound cobble. No other stones look like wood in them. Just the stone you mentioned. IMO it looks like Texas wood in 2nd photo. |

Dang James, that is some solid conglomerate, not crumbly at all. I'm surprised at the variety of the color palate.

I have to share some of my conglomerate tumbles, thought you might like em'. magicalrocksandminerals.tumblr.com/They came from a cobble plate about an inch thick, maybe half a pound... before I took a sledge to it. Conglomerate interests me very much. |

I like how it's a tiny mosaic, and the jasper/petrified wood that make up conglomerate is dependent upon the material available from the same locality. Or maybe the bits could all came different localities and were brought together by alluvial flow, then, under heat and pressure, cemented into conglomerate...

You would think the geologist could deduct a lot of information from the conglomerates. |
