I have some silver like rocks i found here in ohio while out on the creek the other day .. can you help please.
I also found a pretty cool fossil too.

I did the mustard test on them ( poor mans acid test ) no results. FYI

Georgia Dirt and Rocks

Good Afternoon to all! I'm knew to prospecting/rockhounding and need some help with identification. I have an area that I started digging recently because it was sinking in and a crack on the surface of the ground started to form. I continued to dig because I came across soil that was not the typical Georgia red clay I usually see. This soil has a lot of yellow-gold color, metallic like flakes that make everything shine, some gray to white clay (clumps), yellow-sandy like dirt (does not clump), red clay, and brown dirt, and also these rock-like clumps that are mostly assorted layers of colors when broken. I have attached pics of the soil in the hole and a couple of rocks I have found. I am located in the western part of the Georgia gold belt and gold has been found within a 5 mile radius of where I am digging. I think there may have been a stream in this immediate area SEVERAL hundred years ago, but I do not know how to determine that. I am not necessarily looking for gold, just curious as to what I can find.
Is this hole or the rocks in it worth pursuing? Should I try a different area? There are various shades of quartz rock all over here. I have heard the phrase 'the redder the better' and to look for iron staining, but everything here has red or iron staining bc of Georgia red clay. Thanks!

I've got a couple items that ended up in the sluice that have me stumped, one is some type of nugget the other I kept because it reminded me of jade especially when wet.

The nugget weights in at 5.09 grams, its not stone defiantly some type of metal or alloy. I grinded the corner to see what it looked like and it left a black mark on the stone wheel, reminds me of tungsten or graphite. Found in northern California. I took a photo next to a 1/4 oz lead weight for comparison, I don't believe it's lead as its larger but weights less than the less weight and it feels much harder. Also its not magnetic.








Second is a nice size flat stone that is very green and looks somewhat marble like but it's hard to tell since its so ruff.. I've wetted half of it to show better. Found in the same location.




Any help with an id would be great!

Georgiagirl: Decomposed granite.

asm, I'd suggest you have someone look at it in person, the little "nugget". The fact that it gives a black streak and is non magnetic makes it interesting.

As for the green one, could be epidote.

Found in se queensland Australia. I think it is dirty quartz? Wondering what the silver specs might be that are running through it.. Dabbed bleach on one of the spots and it instantly turned black. This is an extremely new hobby to me (about a week) so I apoligize if my info sucks

Hey El_nombre,

Try showing your specimen over in the Rocks/Gems forum. You'll likely get a faster response. -Luke

Looks like quartz. The shiny things might be mica.

 

[seahorse]

is this rock a meteorite or magnetite

found in stream is about 80 pounds has glitterystuff inside plus black looking glass. magnets stick all over it and any kind of magnet. the holes i tryed to drill with hammer drill and only got 1 half inch. rock is heavy. the small chiped peices are thin and stick to magnets in last pic. grey powder also sticks to magnet from drill holes. thanks for looking. almost forget i have a newer mxt pro metal detector it actually screamed and vibrated at same time and only in one place on the eloganated high point of rock like in first picture at top of rock. also pinpointed there. sound from detector did not move around in different spots on rock as i believe would have been a signal of a negative mineral.

 

[Eu_citzen]

I'd like a better focused image, but it might be gabbro. Gabbro often has magnetite in it, which makes it magnetic.

 

[seahorse]

maybe meteorite or gabbro

hello,hope this helps older camera.

Hello, got some close up pics here i think you will like. New phone i bought my 14 year old. i have some more rocks i hope to send you to look at. I dont know any thing about mining and decided to buy placer claim. rocks i have are mostly different colored quarts. thanks for looking.I think you might be able to zoom in on these pics, please let me know .

 

[Eu_citzen]

Try taking a little bit further away, if you get to close to the rock it gets "blurry". Or try taking through a magnifying lens, look closely so it doesn't look fussy.
Just so you know, your getting a guess at best. If I were doing this properly I'd be holding it in hand and examining it with a loupe. (10x magnification)


Your last set of pictures look way different then the previous ones. Are they all of the same rock, or am I going missing something? LOL
I'd want you to look at the bottom picture of this site, look for "gneiss".
CLASSIFICATION OF METAMORPHIC ROCKS

Does that look close? I'd invite you to look under magnification for "greasy" to "glassy" looking lumps/bands, quartz. Often a white, greyish-white colour.
That looks close to the last set of pics.

As for these:

Those looked like gabbro, but granite is also possible. Again look for the "greasy to glassy" looking lumps of quartz under magnification.
if you find quartz - granite. If not - gabbro.

Would anyone mind helping me identify the mineral within this rock? Any help would be greatly appreciated, thank you for your time!

 

[yolderboy96]

Here are more pictures (it's only letting me post one at a time) :

Another picture without the flash

 

[Eu_citzen]

Could by Pyrite, chalcopyrite or even a brownish mica. Rather difficult to say from the pic. Research them and see what could fit.

This is the bedrock in my yard; about 8 inches down. Sparks when struck with a pickaxe, and is magnetic. I'm assuming that it contains iron, in some form. There are small metallic crystals dispersed throughout the rock.
