Is this a rock? - UPDATED PICTURES

[gargreen18]

What it this? Looks like... well I am not sure. I thought a melted glass but then I found another one 4 miles away at another site. What the heck? Maybe it is melted glass. I dunno. What do you think?

The first 2 pics are one "rock" and the other 2 are the other "rock."

Mrs.Oroblanco, Is Right ,quartz does melt, an you can melt it at home with a kyln,, especially if there is gold in it!

So here are some pictures,, It is cloudy out ,and I was in a hurry,,,Hope this helps all who finds agates.

#1. All shapes and sizes, The environment and host rock where they are formed says a lot about what they look like. The one in the top left was formed in lava pocket that was lined with Calcite crystals first.

#2. Small Fortified agates, the ones at the bottom are fire agate.

#3. Gas pocket agate in the host rock or 'matrix'. the one on the right is fire agate in ryaolite, and the second one is just plain lava.

#4. You never know what you have till you cut them, or break a chunk off.

#5. After cutting most are really cool, but some are just bland, or just grey.

#6. Part of my collection, all hauled home by the wife and me.

Re: Is this a rock?

Quartz doesnt melt,your object appears to be melted.Even Quartz water worn does not look like yours.Still neat

I again stand corrected.Quartz is a silica and in liquid form when it was thrust up through the plates with gold.I dont know why I said that,and thank you folks for keeping it real!!

Although this thread is already green-checked, I am going to throw a more, hopefully, exact ID: sodium potassium aluminium silicate, AKA "moonstone." I have many, many examples, and quite a few of them have that white patina as well. Did you find it at or near the beach?

Wow! That sounds exact. I love when I learn something new. No, I live in Spokane about 400 miles to the nearest beach.

All you folks are great thanks for keeping this thread alive and I enjoy checking it daily to see what you all think.

Just to "wiggle the boat", it looks like part of my chalcedony collection!

Of course, chalcedony IS a component of onyx, thunder eggs, a "precursor" to opal (where there is opal there is almost always chalcedony),
and many other things that people like me, collect! (including moonstone, btw).

It is a "Gas pocket" Agate, basic chalcedony,and quartz. I have picked up tons of them.
Arid.

You know what?You are right.I will eat the crow!Those are all over Nevada,I didnt relize they had Quartz in them though!
I have an arrowhead(original)made out of Chalcedony

Looks like lots of stuff. I think I will take it to a rock shop here in Spokane to get the final verdict. I will let you all know.

Thanks for your input Beth.

Just to throw something in here, but these are two different rocks and they do look to have differences so wondering if people are judging one rock or two as to what they are? The lavender rock still looks like a rose quartz and the other does look quite different. Just wondering.

 

[mrs.oroblanco]

Could be, could be.

Volcanic activity did LOTS of stuff to rocks, and made them into liquid type states - things that could cool and dry in one form, get in between other rocks and lava and become other shapes, etc.

Much like onyx, moonstone, chalcedony, obsidian, thunder eggs and opals are all "related" in how they got to be what they are, they can either be from a different "family" of rocks, or the same family.

Kind of like talking about carbon-based rocks - from coal to diamonds - certainly different specimens, but related.

Rocks are so much fun, aren't they Even when gold panning, I'm grabbing "pretty rocks" from my pan, or my dredge or my highbanker.
