Got A Rock you Want Identified? Post it here! gimme a good picture or 3 or 4!

Dusted, chemically, how far apart are Turquoise & Chrysocolla? They look very similar and have some of the same minerals.

Rick they are just a hair apart:

Chrysocolla is a hydrated copper silicate mineral with formula (Cu,Al)2H2Si2O5(OH)4·nH2O.

Turquoise is a hydrated copper silicate mineral with formula CuAl6(PO4)4(OH)8 • 4H2O

The major difference is that Chrysocolla is a stalagmite in formation and was used by Greeks and Romans as Flux. due to its lack of Phosphorus.
Turquoise has the Phos and tends to cup or repel gold and silver within it instead of bonding to it.

or turquoise both gorgeous!

GSXraddict , I would venture that it is a metamorphic foliated Shist or granite... but i seen some green at the tip.. do you have a little clearer picture?

 

[Rawhide]

Thanks, I wondered why it was kicking my butt. Man I pan buckets of samples that I gathered and take home. There is plenty of this about 30' up on the banks.

it's all green and white, rough texture. I don't have another picture, I left the rock at my dads house in another state.

Here is a link to a post that i made a while back but noone was able to help. Perhaps someone here may have an idea. Thanks!

Pat, I was looking at the first shot it seemed that there was powdered limestone or sandstone behind it .. It looks like you have a Granite (ballista or bubble from deep within the surface that was given plenty of time to cool off IE the quartz veins, and mineralization.) <img src="http://www.treasurenet.com/forums/attachment.php?attachmentid=782200"/> the red and greens being Iron and Copper mineralization. It could also be carried on the surface by water or ice to an area its not from. the second picture you have is definitely granite, it has pockets of hot gas in it from when it formed. These typically form 22km under the surface and are thrust up via Volcanic activity , plate movement or earthquake, then cut back by erosion.

thank you dustedyou.so does it contain any precious metals or precious rocks?

 

[Dustedyou]

Checkman... ok so you have found Nickeline or niccolite is a mineral consisting of nickel arsenide, NiAs, containing 43.9% nickel and 56.1% arsenic.
Small quantities of sulfur, iron and cobalt are usually present, and sometimes the arsenic is largely replaced by antimony. This last forms an isomorphous series with breithauptite (nickel antimonide).
While rare it is Extremely Toxic.
This is a sulfide minerals are a class of minerals containing sulfide (S2−) as the major anion. Some sulfide minerals are economically important as metal ores. The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts.[1][2] Sulfide minerals are inorganic compounds.
Apparently the Germans after not being able to get the copper or nickel out of it and becoming sick decided to blame the "Ore Spirit" Old Nick for cursing the the metal.

you have a form that is much like Valleriite in that it is completely malleable, and soft to the touch.
for more info on sulfides check out Sulfide minerals - Wikipedia, the free encyclopedia excellent place to start.. love the rare Specimen tho m8! Sweet RARE! be careful!

PATfreak ... not so much on the first one but http://www.treasurenet.com/forums/a...e-gimme-good-picture-3-4-image-3585401546.jpg that one you just posted is yummy! That is a sweet vein with all kinds o mineralization... good source of gold to say the least.. i would crush and pan .. or just stare at it for a while..then crush and pan.. hehe the Quartz Iron copper and molybdenum is exuding thru it and .. well Yumm!

 

[gsxraddict]

did you see my reply above?

 

[Dustedyou]

GSX yup... my guess without a better picture is that it is a tsavorite Shist..

Rare Green Garnet schist.. the large ones
Are gorgeous.. i would look (if you can) for a much hotter spot in the rock,, one that would have more mineralization in it or be cloudier and look for the large Green crystals! yum yum!

yeah,i was kinda amazed too when i look at it too i got it on my way home saw a very large rock just like what youve said about 2-3tons big..so i cut it using a crow bar..i dunno how to crush it and mill it since im just an amateur in terms of hard rock mining/gold panning.or just do the old fashion way of hammering it to dust...i attached the mother rock i get it from.

 

[MrLee]

Ok, here are two more, smaller samples of the same rock. I am going to say chrysocolla inside copper, but what else? The rock is from our new claim which has a silver mine as well as gold placers. How do I know if it contains silver?? The Chrysocolla goes from a light turquoise to a deep blue turquoise. Really nice stuff.




Thank you so much for sharing your knowledge with us. It's already helping me in identifying things. Let me know how I can repay the favor.

Oh ya, the host rock of these also has peacock inclusions, small, metallic, rainbow covered spots.

 

[Dustedyou]

hummm... nice samples there to tell i would get a piece say 3 inches in diameter and any length ,, cut it in 1/2 using a tile saw (harbor freight 29.99) if the Green melts away and doesn't take a polish its probably Chrysocolla if it holds a polish take bees wax or parafin and rub some over the green,, you should see striations of metals in the blue to green of little "Treelimbs" of gold copper or silver. Either way if its of a good strength it will sell as is to a jeweler (indian jewelers supply or rio grande...) as for the Chrysocolla if you cut it you should also see rings (like a tree stump) within the formation... after cutting it again with the bees wax (lasts longer) or parfin from a candle rub some on.. (heating rock in the sun beffore helps alot) and look for most Chrysocolla has voids in it also (beautiful chasms) . the Turquoise almost never has any chasms. looking at that rock... i would so be slicing it up... hehe i actually did that to hundreds of samples in an afternoon just to get a picture "Inside" without smashing it ... and now have "Bookends" for the next 5 or 6 generations.

 

[hurthawk]

I will try to post as many pics as I ca n of this specimen.

[Dustedyou]

Hawk, like i posted earlier I do believe : you have a type of Jadite

Jadeite colors can range through the color spectrum with more exotic colors.
Jadeite: NaAlSi2O6
Color White, Blue, Red, Green, Yellow, Orange, Brown, Pink, Purple, Gray, Black, Banded, Multicolored
Hardness 6 - 7
Crystal System Monoclinic
Refractive Index 1.60 - 1.67
SG 2.9 - 3.7
Transparency Translucent to opaque
Double Refraction -0.027 (Nephrite); 0.013 (Jadeite)
Luster Waxy, vitreous
Cleavage 1 or 2,2 - prismatic. Due to lack of visible crystals, cleavage is rarely observed.
Mineral Class Jadeite or Nephrite (Nephrite can be either Actinolite or Tremolite)

GORGEOUS ROCK!

That rock should go directly to a gemologist (whom is going to drool) Its a perfect specimen of Jade (traditional colors) and creams and the Red is extremely rare. A Jade stone of that mixture should fetch $1.00 a Gram or more.. and i would settle for no less... An extremely Sweet find!

On a secondary note I nominated you for a banner! Not often that us Prospectors get a woohoo!

 

[Dmax]

hey dusted here are a few pictures. i have a few mountains on my property that have this type of rock all over them. they form a ridge on the top of these mountains. south central arizona... mammoth district. thanks can i expect to find anything here?

 

[Dustedyou]

Dmax it quite possible the 3rd picture has good signs of quartz mineralization.. i would get a loop and check out the quartz. I would also start looking within the rocks for talc and red from iron this will "Guide " you toward a good vein, red (iron) or Green (copper) is a nice indicator of good mineralization.. but are not allways present.. thats why i would suggest a loop and a close look at the Quartz area. these are "Good" examples of what to look for , but there are many others. here are Mamoth AZ gold picts
good examples of where you would find some gold... ALSO Check out the GeoCommunicator its a great tool for looking at your spots ,, surrounding spots in topo or satilite, and finding old mine claims.!! GL and get some!

Subject 1: Hard, shiney inside, can be picked up with a magnet, beeps for metal.


Subject 2: Frail, breaks down to black powder, colorful inside, beeps for metal.
