Where was it obtained from? Too me, the first stuff looks like sandstone, and the agates look like random river/ground agate from no distinct locality.

The agates could be Prairie Agates from SD or Nebraska. jasoninsd What do you think?

They kind of remind of Bahia or Prarie Agate, not saying that's what it is though.
Should throw it in the tumbler and see what it looks like without that crust imo....

They were picked with permission from landscaping rock in Indiana tho the guy who gave me permission had no idea where they were from originally. As far as the first two, I am not sure they could be sandstone, some parts feel rough like sand stone but some parts feel smooth and waxy, so no clue, jasper was an offhanded guess to be honest lol.

Someone said one is silicified stromatoporoid in the mich rockhounds group on Facebook.

The first two images look like weathered chert. Check hardness. Images 5 & 6 clearly show quartz with agate. The rest are a weathered agate. It would be interesting to know where the gravel came from. I have found gravel from Brookwood AL in a Holiday Inn in central IL so it could be from anywhere.

I was at the company that sold it to the landscaper that used it yesterday and they were unsure where exactly it came from, but the guy thought it come from somewhere in the Mississippi and surrounding states area. Got 3/4 of a 5g bucket of agate and what im guessing is jasper, flint or chalcedony and only cost me 5 bucks. I could get a full cubic yard at about 2200lbs for 155 bucks.

First reply on Mindat
"Most definitely a Crowley's ridge agate. And you would have been working in missouri or arkansas to find 1of these."
Waiting to see if anyone else chimes in to confirm it, but looks like these might just be Crowleys Ridge Agates after all!
Asked how sure he was, this was the response.
"Oh yeah i'm a hundred percent positive that's a crowley ridge agate. I've been collecting em and tumbling them. Here I find them in the big river and they also spill out into the meremac river near me."

First pic looks like, kinda, but definitely is not sandstone. If you look at the right side of it you see conchoidal fracture like the bullseyes when a bb hits window glass or knapped arrowheads. They narrow it down to a silica based stone, so jasper, agate, opal, chert, quartz, flint, obsidian, and so on. Fortification makes it metamorphic. Those look like they will polish nicely.

That was what threw me off on it without the conchoidal fracture I would have guessed sandstone too! But it sure feels like sandstone even tho I know sandstone does not conchoidal fracture lol.

Looking at the first one more it looks like chert and limestone mix. The soften indented part being the limestone and the raised part being chert.

I think a lot of what isnt agate that i got is either Flint, Chert, or chalcedony. Most of them look Nothing like this one. The entire rock looks waxy brown, but the ones that are broken look almost whitish/bluish inside, What ever they are, they are HARD and grind just as slow as the agates do. Got some of them in the tumbler right now.

So just an Update here, the Blend where I got these is called Meramac and through more research than I would care to admit I did, rmf I found that they most likely came from the Meramac river in Missouri and I guess they do a lot of mining on that river for landsape rock and chert and Crowley ridge agate are common, along with a couple other like dolomite, Goethite,and limonite.
