Pock marked quartz?

[eureka77]

I've been finding gold every time that I go out lately based on the info I read on the web and through expierences on my own from going out, and then using that info to dig my ass off and process material.
I'm still learning and going to ask stupid questions like this one. Are these pock marks or little craters in the quartz where gold once was or just where the quartz was attached to the host rock?

most likely just the way the silica solution cooled. pockets in side quarts veins are the home of sweet crystals.

Thank ya. Wass always curious

Most likely those cavities once contained softer minerals that were easily dissolved by acidic water, unlike quartz which is very tough. Fluorspar for example or calcite, but there's countless other options as well. Those crystals are good omens, I find much quartz up near Vein Mtn just like that. And another spot that has gold here in SC also has such rocks. I will try to post some pics of the ones I got when the sun comes out.

Looks like where the iron pyrites were..note the rusty brown..and you'll notice in your pickings that many of the cavities are squarish,where the cubes once were.

This is what I think also. Sometimes you will see little pieces of pyrite that have not decomposed yet and that is a good indicator for gold.

Good looking quartz. "Dirty quartz". The pock marks probably did NOT contain gold. Oh, BTW, when certain minerals are added to quartz, you get some very pretty crystals, but quartz itself does not make crystals and breaks without cleavage. TTC

quartz is like the second most abundant mineral in the earths crust....and it does form crystals!...trig . and when you crack open a piece of quartz float it will have/can have holes,bubbles ,vuggs all sorts of pouracity(sic) depending on the deposit, that have nothing to do with alluvial erosion.just the way the silica solution cooled under preassure and depending on those preassures temperatures and the prescence of other elements besides pock mark holes you find citrine, feldspar,amethyst,agate,geodes,onyx,jasper,carnelian......voids make the crystals.....even under pressure

sometimes from erosion of softer minerals....but not always.

Those vuggy pockets can also be the home of the sweetest crystalline gold, as it has the room to grow. Quartz and porphyry with cubes of limonite crystals and black manganese, red stained quartz.
The more mineralization the better.

that is exactly what i meant by sweet crystals....

Here's one of the rocks I was talking about that I took back to my house, from Vein Mtn Gold Camp.



Sorry I don't have more pictures, but you can see the crystal pockets in there, which I thought was so neat.

I to have some neat crystal specimens.



I am looking for ore close to the findings of those crystals, though not gold but Galena.

When quartz is formed, usually hot fluid. Bubbles can occur, called vugs. Others have suggested these contained pyrites are are worthless. NOT SO! Gold can frequent the interstices between pyrite crystals and quartz. Not always, but sometimes. That's what assays are all about.

Herman Oliver Museum in John Day, Oregon has a beautiful specimen of pea-sized gold nuggets embedded in rotted quartz. Upper half of this rock is chrysoprase, a semi-precious stone also called nickel bloom: a kind of transluscent light greenish stone, very common on Little Canyon Mountain, just southeast of John Day. If you go up to the cemetery and continue up the mountain, some interesting rock collecting areas will show themselves.

Must have been seeing things man all these years....ha,ha,ha.Must have inhaled some of that drifting smoke the DEA agents caused when burning up the fall harvest.Believing those little cavities in quartz once held sulphides/pyrites,whatever.Excuse my dust BRO,I bow my head to you.Dave in the motherlode. 8) I do wear my sunglasses at night and slept through most earth science classes.

 

[Goldwasher]

sorry if that response was because of my post dave?? i wasnt saying you were wrong..just adding a little more info wich is what the original post was looking for.i never said you were wrong and didnt mean to sound like i was absolutely right. i have only seen these rocks in pictures so im only 98% sure im right...... ........just teasin BRO

 

[dave wiseman]

No biggy,need a little more posting and action on this part of treasurenet...
