BrotherofPeace:
#1 A granitoid, maybe? Uncertain.
#2 Green epidote on quartz
#3 Mineralized quartz.
#4 Granitoid, again? Uncertain.

Telemachus,
I'd imagine it could be pumice.

Pumice would be a good guess, but it's pretty hefty, because there aren't all that many air holes. And a large % of the air holes include little flecks of something colored like terra cotta.

what is this im sure its a gimme but I was wondering what the white spots are?

 

[Grislybooch]

Calcite?

Found all of these where there's both limestone bedrock and sandstone in the southern parts of the Ozark Plateau in far souther Missouri.

Actually, the little flecks coloured like terra cotta are irrelevant for identification I think.
Another possibility is Scoria. Those are the two candidates I can remember. There might be pyroclastic candidates to, but their names elude me.

Desert-rat:
I'm not certain. Could be feldspar.

Grisly,
Unusual looking rocks! Where did you find them?
First thought was slag, but that'd be a highly unusual looking slag. Could also be chalcedony.
Try scratching it with a quartz.

Icewing,
The egg-shaped rock might be agate as it looks banded.

The thing that sticks to a magnet might be sandstone with magnetite in it. Or even pyrrhotite.

This fellow below, try and see if he reacts with acid - vinegar will do - if yes, calcite/limestone related.
If no - probably quartz related.

I found this one in Missouri. Very colorful and sorta ??holographic?? Lol I say that cause you look at it right n there's 2 yellow eyes starin back. Anyway any ideas

 

[Joshua donegan]

Kinda neat resemblance huh?

 

[scotter1]

how about these.found these in upstate ny they are very shiny and sparkly but not detectable or anything.black,deep rust color with i think garnet and quarts in them.

 

[Joshua donegan]

Scotter1 those are pretty cool

Very heavy for its size, will barely attract a magnet. Filed area is silver. I cant scratch it with a knife blade. Would love to know what it is.

On AT Pro it comes up 62 which should be Nickel.

OK Hambone, I'm never one to mention this but you need to get that chunk checked out. Doesn't look like iron slagy or manmade weathered metals. It slightly attracts a magnet, and comes up at a 62! Not pegmetite, not vein material, doesn't look like massive galena, is harder than well...rock lol.
You just may have yourself a genuine Iron type Meteorite.
Don't get too excited, because there is soooo many weird things it could be, but that is Definitely a piece worth having someone qualified have a look at!

 

[Hambone1]

Thanks GrizzlyGremlin, I will one day have it looked at, I love messing with it, I never get tired of picking it up. It always feels like it is attached to the table because it is so heavy.
It is also rough looking but smooth feeling.

Look here for how to identify as a meteorite. https://www.google.com/webhp?source...576US576&ion=1&espv=2&ie=UTF-8#q=meteorite id
I would do the scratch test first. You can use the underside of a toilet cover if you do not have a piece of tile. By the looks I don't think it is a meteorite but more likely Magnitite or some other iron mineral or combination. https://www.google.com/webhp?source...76US576&ion=1&espv=2&ie=UTF-8#q=iron minera;s
