Howdy folks, Still cutting some oddballs from the Rio pile. Both of these are unknowns. Anybody have an opinion on what they are, please chime in. Thanks for looking....Mel Thought this first one was some kind of wood. Wedge shaped and definitely with a pattern on the exterior. After cutting, I'm leaning more towards a big pseudomorph of the sagenite class. What do you think? Exterior:  Interior:  Wish I had more of this stuff as the pic really does not do it justice. Really smooth solid stuff. Only a single broken hunk though. I thought at first it was some kind of dolomite but if it is, it's fully silicated and turned to jasper as I tried to scratch it with a knife and the metal comes off on the rock. At least mohs 6 or so in hardness. Maybe another of those strange tiger tail relatives. Who knows?  |

Scott, A lot of what is sold as "Tiger Tail Jasper" ( if striped) and "Cheetah Jasper" ( If spotted) comes from the Rio grande gravel. Seems to be very variable stuff and is all about the same hardness. I was just speculating that this stuff seems similar in hardness, exterior look, and texture except it lacks the black areas of manganese. Maybe it's just another variation from the same sort of deposit. I really don't know......Mel

I have a known sagenite spray, similar to what you discuss, from the north side of the cadys. Its is a couple pounds, bigger than my fist. Not river polished. Maybe i should slice it.

Scott, I too have found huge sagenite sprays in the North Cadys. Most I've cut have been very vuggy or porous but I now so guys that have found truly incredible solid agatized pieces too. The Cadys are pretty famous for both sagenite and plume.....Mel

Nice, that first one is outstanding. Great material - Rio Grand - where is that? I've been to the headwaters of the Rio Grande in Colorado but it's a long river.

timloco; The Rio is the southern border between Texas and Old Mexico. This material comes from Carrizo Springs, Texas right on the river....Mel
