This is a rock that we found in western Washington on our fishing vaca. We do not know what it is, any help would be great. Thanks for looking, Tammy

I'm color-blind, but it sorta looks like jade to me.

Hey Randy, do you know what the stone is that is used in the Tut, Shaping a Cabajohn, it looks a lot like this rock. When I cut it, the matrix that is more yellow can flake and leave you with a nice chunk. But the whiter matrix is solid. The color is a grey-green.
Any help is great.

What river? Could be jadish mix or more probably serpentine. Woodyrock on here would probably know if you tell him where you got it. He's on the westside too and has a wealth of info on WA rocks.

Sorry that I have not responded sooner, my health has been bad. We collected it from the Grey's River, a very small, short river that drains into the Columbia River.
Thanks for looking,
Tammy

Its a piece of common basalt with veins of calcite running through it. Looks like its been river tumbled for awhile.
I was up on a fork of the Greys river this past weekend and there is alot of this type of rock to be found in the area.

I agree that river has many types of rocks. We brought home quite a few this past fall. Were you up Fossil Creek, theres lots of loggin going on there, but it is beautiful country.
Thank you, I have a few pieces in the tumblers, both rotary and vibe, I can't wait to see it polished.

thats exactly where I was! Im not sure what mineral gives it the green color but there is alot of it about. In the quarry just past the 2nd bridge, there are pockets of the ore showing up throughout the rock. I have a geological paper that talks about the green ore in some of our rock here that calls it titanium, but being an agate maggot and not a geologist, I wouldnt know for sure. You can drive up Fossil Creek road , and just about every gravel bar will have some quartz, calcite or agate lying around on it. I came across several pieces Id estimate at well over 500 lbs each!. Unfortunatly for me its 3/10 mile hike and 500 ft elevation gain btw the rock and the road! I suppose a day of hard effort and a chainsaw winch could get them out,but Im not that ambitious. I decided to settle for several pieces about 6 pac sized intead.

I would expect the green color is from chloride.

Very cool rock!!
I agree with Roller .... cut it up! See what the inside can tell you.
Dam these rocks .... they do not give up their secrets easily!
