can anyone tell me what kind of rocks these are?

I had these rocks given to me probably 30 years ago when I was collecting rocks as a kit...
I found them packed away in a box about a year ago but I have NO idea what kind of rock it is. Can anyone help me?

Should I have put this in the aquascape forum instead of the substrate forum?

While we can recognize some of the more distinctive types of rocks sold specifically for aquascaping we are definitely not geologists so random rocks collected from the wild we will almost certainly not be able to identify. That said, many rocks are perfectly safe to put in the aquarium. The quickest test is to dribble some vinegar on the rock and see if it fizzes or creates tiny bubbles. If you don't see any then its PROBABLY safe. To be doubly sure put it in a bucket of your water (tap or RO whatever you plan to use) and let it sit for a week. Measure GH, and KH when the rock goes in and again a week later. This will let you know if its leeching much. If it does leech it doesn't necessarily mean you can't use it. Seiryu stone leeches after all, but it will mean you will want to keep up with water changes etc.

Thanks for the reply. I have had some of the rocks in my 29 gallon tank for about 6 months now with no problems.
I was just hoping that just maybe someone knew what I had lol. Never know who knows what on these forums and what kind of jobs and knowledge of things people on forums like this have so I thought I would throw it out there and just ask lol

The red may be iron. Hard to tell from the pictures. I agree with @minorhero about dribbling vinegar on them. I'm a huge fan of sustainable rock collection.

Red can indicate iron if we are dealing with iron ore but since iron ore is pretty hard to find and there are tons of other chemicals which make red, I normally do not expect to find iron in enough quantities to bother me. Red River along Texas-Ok border or red clay of Georgia for instance?
But the rock type is likely to be a combo of various types from what I see. First there looks like layers of sediment and then that sedimentary rock looked like it was remelted and moved and shaped making it Igneous. So many ways to form rocks but one of the more common types is conglomerate meaning it is a combo of several other types.
So you may just have a conglomeration of rocks in the sink, none of which are hazardous! If you have good hard water with lots of buffering (GH/ KH) you are not likely to see any change when adding a few minerals from rocks which degrade really slowly. If you have soft acidic water, it takes more watching as you have no buffers to resist change.
EDIT:
Just looked at your location and might want to change the idea of iron, depending where they were collected. If from SE of you, in Rolla area or SE, there is a better chance of iron there. Still would not worry me much if the snails are happy.

Im not exactly sure where they came from. It was given to me many many years ago by a truck driver who found them on one of his many trips around the US

That looks like iron ore, I wouldn't use that for an aquarium. It may contain varied metals and chemicals in unstable conditions.
