Did some more grinding on my everyday average crow cracked olivine find ![https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1637006034/Overload/olivunecrwcrackedlongslopeNov2021_3.jpg](https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1637006034/Overload/olivunecrwcrackedlongslopeNov2021_3.jpg) At least I think it mostly olivine w/ lots of horneblende silica ect,,, Whatever it is -came form deep in the earth as I crow bar cracked it from seam in the granite piedmont Best so far all i can get is countertop finish That radius slope is about 3” x 2" Hard & slick

That's a pretty rock, good color and will make some nice hearts. Looks a lot like epidote that we find in the NC mountains that's associated with granite.

Does it form near the same or a much later time? It's a really neat piece.

This probably came out of a rock quarry. I found it in some riprap in the mountains of NC. I have the only one that I know of. As an agate hunter in KY I knew what to look for. This "pot belly" looking rock had the void it needed to fill. The void came from gasses when the original matrix was cooling down, leaving a place to "chill-out" for the hot-pressurized-epidote-solution.

It's a hydrothermal metamorphic process where hot water is boiling up like Yellowstone Park geysers. A calcium solution shellacs the crevices that the water and steam pass through. The hot liquid cools off as it crystallizes -- leaving a pea-soup colored residue. We call it epidote. It's a pistachio earthy kind of color.

Right on ![(chewie)](//storage.proboards.com/1258779/images/wzwYPvtiqNvJ_dEBAoAI.gif) thanks all for the interesting info the green may very well not be olivine could very well be an epidote vine ![https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1637081102/Nikon/unionhillvine.jpg](https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1637081102/Nikon/unionhillvine.jpg) interesting blurb I saw online olivine doesn't associate well with quartz and the seam was quartzy

This as turned out be quite the study and I can't pretend to explain it even tho after all these posts my moniker is can identify rocks- even green ones ha Butte I always naively assumed most Green rocks were olivine based Wrong Actually a very few percentage are -if any I guess These clasts in the Papago Buttes Must be some combination of epidot, chlorites ectal ![https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1637164028/Overload/papagochunkDSCN0469_3.jpg](https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1637164028/Overload/papagochunkDSCN0469_3.jpg) What is commonly referred to as greenstone Because there so convoluted meta morphed Please keep adding your geologically informed insights...

I finally spotted something unique to the Papago area area on a hike this morn A little Quartz seam nugget in epidite I suppose ![https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1637777273/Overload/papagoquartzseam11242021.jpg](https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1637777273/Overload/papagoquartzseam11242021.jpg) Tomorrow I’ll try polish a side... till then or before mohs

Admittedly this is not a very good picture of another unique find in Papago Its shaded Get a better shot, when the sun is setting Should light up better Its large chuck of black lava scoria Those vesicles are glassy melt & obsidian sharp Apparently someone defaced it what I think is paint Although I’m not sure Plan on bringing over some acetone & brush and see if I can’t clean some of it If it is latex paint Any have suggestion of best cleaning method? Thanks ED

Acetone will do it. But, it would take a lot. Maybe turpentine or mineral spirits?

on small area just tried some acetone & gunk wire brush nogo the vesicles are so rough, sharp, and deep tough to clean

pretty sure this rock was hauled in perhaps from Sunset Crater ? ![https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1638295556/Overload/papagpblckscoriaIMG_3348_2.jpg](https://res.cloudinary.com/rock-n-hearts-inc/image/upload/v1638295556/Overload/papagpblckscoriaIMG_3348_2.jpg) try to track down a park ranger and get some info on source ...

thank miket ! you find any lava type rocks in your travels? Not really around here, my friend... Right on Mike How about seashells? Over in Papago I’ve found many tiny white bi-valves shells Sea-shells in the desert. Seem strange. Today I was doing some digging in soft soil spot in that park. That hard to find in that area. Its acres & acres of granitic rocky clastic piedmont. Drive a couple miles away & all you’ll find --for miles & miles & miles & miles ect.... -I’m talking whole humongous valley basin- is nothing butte deep soil/dirt filled land Hardly a rock to be found All that said: in my dig I found a different type of shell. besides just the tiny white bivalves Little white nautilus type shells like ammonite shape- but modern- I suppose have to get a picture Anyway just wondering if you find sea shells in your area? My idea looking your basin pictures is that land raised from some ancient sea.
