Random fossicking adventure in Chile - Chrysocolla?
« on: August 16, 2013, 02:41:03 AM »
So, I was taking the dogs for a walk in an offroad location, about 5 hours away from where I live in Chile.  I came across some diggings, and lo and behold, I saw blue/green.  Lots of it.

I drove the car up, and loaded it up with the brightest and best.  I THINK this is Chrysocolla - what I'm unsure of, is whether it is solid through the rock, or is just an outcrop on the surface.  If Someone with more experience with this material could chime in, please?

If I'm correct, then yes, I have the GPS co-ordinates.  :)

Peg, perhaps Omillett is talking about Chile Creek in W.A. ( somewhere near Dampier) ???  Well I hope its in Australia, I think trying to take my pick, crow bar and shovell to the other place might proove difficult. ;) ;)

I get a lot of chrysocolla of different grades in NW Qld. Wouldn't call myself an expert on this material but I have broken up lots of chrysocolla and cut, slabbed and cabbed quite a few pieces.

This looks great, a standout colour but most of what I'm seeing may just be a surface coating? If so, it could be of little cabbing value.

However, you often get the chrysocolla occurring in bands and patches throughout a host rock so it could still have cab potential that you won't know until it's broken or cut.

The host rock looks solid but check for porosity. Is there surface pitting? Put some water on it and check bubbling or absorbency that might indicates it's porous or otherwise. If its porous, it won't cab well although it could be stabilised with a  filler.

Some of the chrysocolla I get can be brittle too. Do the corners chip easily?

This is indeed, Chile, South America (where I live).  Location is close to the town of La Serena.  I have the GPS co-ords in case anyone wants to go for a dig there.  :) 

I too am worried this is mostly on the surface.  However on the large piece I photographed, the blue is evident on all sides of the rock, so I'm HOPING it runs through.  I don't have any lapidary equipment at the moment, so can't cut it open.  The rock is not porous from the water test.  But the colour is brilliant, and there was lots of it (I filled the back of my Xtrail, to the point where I was scared for the shocks!) so at worst I have an interesting blue rock garden.

You do get around Omillet!

'Tis indeed a fabulous blue.  ;D

If you have lots and know where there's more ... bust a piece apart amd see what's going on?
