Hi Bill....I am a jade hunter first gold second...while prospecting in a creek I found this first small rock then a set of multi ton boulders.......that I thought could be BIF's....when I read they can be related to gold that got me curious......then when I read they are like 4.5 BILLION yrs old..considered some of the oldest rocks on the planet...I thought they may make a nice lapidary pendant, with a great story...basically here at our planets formation...too cool...so I am looking for a way to id what areas to look for the main formation...most of the rocks I deal with are much much younger...again..it is fun to find new things while prospecting

Correction on the age of the BIF's....they are mostly considered 1.8 to 3.8 ( GA ) Billion yrs old...

Very purty rocks and good photos. Looks like jasper.

I to think they are a very nice looking stone. I wonder how they would polish up, could be that the iron bands won't take a polish. But even so, that might make an interesting cab. Give it a try and I'd be interested to see how it came out.

Thanks for the post.
