Explain My Strangest Lake Superior Rock

[@jerryb2128]

I think that the big-one with red and green at 4:26 is a ironstone

[@ThirdPlanetRocks]

I had someone else tell me that one could also be a stromatolite jasper. Know anything about those? Normally I agree that red makes me think a stone may contain iron

[@meredithseymour5847]

Swirly rock at around 4:10 mark is Mary Ellen Jasper :)

[@ThirdPlanetRocks]

I am terrible at identifying the different types of jasper. Thank you!

[@MaynardCrow]

2:50 Did you run a magnet over it, see if it responded?

[@MaynardCrow]

Another thing is running a dremmel tool or grinder against it and seeing if it makes sparks + if it does, what color the sparks are. Also, if you got a forge or kiln, seeing what temperature it melts at.

[@ThirdPlanetRocks]

A couple weeks ago actually - non magnetic. Dremel is a good tip. It's a shame all 3 of mine are broken lol

[@MaynardCrow]

@@ThirdPlanetRocks Some minerals are hard on those dremel bits. Not everything shaves off as smooth as soap stone.

I am going to guess your silver blob is melted Aluminum from a past bomb fire. Could the huge piece be slag ? I hope to get to the North Shore this summer. Interesting finds for sure 😊

[@ThirdPlanetRocks]

I agree with your silver blob theory! The texture of the big one with the black chunks doesn’t seem man-made

[@richarddargis758]

It’s melted aluminum from a campfire if it looks metallic. It’s slag if it breaks like glass

[@MaynardCrow]

My first thought when he said it was light was aluminum. Looks a little too dark in the one shot, but dunno the lighting conditions.

[@alphakitten7040]

Your weirdest rock looks like a clump of bryozoan in chert to me. The “bubbles” you mention look a lot like cross sections of bryozoan stem. The black parts are possibly side views of the stems. They are too water worn to see the cool bumpy bryozoan texture, which is a bummer. Cool find though, even if it’s not bryozoan.

[@ThirdPlanetRocks]

I agree with you! I think the black color and the crumbling texture makes me think the inclusions are organic. I’m going to look further into bryozoans. Fossils aren’t something I know a lot about. Thank you!

[@savagesquirrel9828]

I think the lump is aluminum….did you do a magnate test? The weird rock is fab…I’m going to guess some fossil…maybe coral? Thanks for getting your feet wet!

[@maryannhamel3177]

At minute 4.00, petrified wood.

[@ThirdPlanetRocks]

That’s an angle I hadn’t thought of. I’ve never seen anyone pull petrified wood out of Lake Superior though. You’ve got me curious now…

[@MaynardCrow]

Doesn't look right to me, but any new theory is interesting.

[@ThirdPlanetRocks]

@@MaynardCrow I’m leaning towards fossilized marine life, rather than wood. No defined grain or direction

[@ontherocksorganiccreations]

I’d say they are conglomerates

[@ontherocksorganiccreations]

And the last one could be breccia

[@ThirdPlanetRocks]

Yes, I’m confused if it’s fossil in sedimentary rock or breccia. I probably need to do some acid testing on both the black and tan portions

[@sallyleary7712]

It's concrete and has green tints from the water that changed their colors but it's concrete mixed with rocks they put it color. That's landscape rock color rock

[@sallyleary7712]

It's a thing for cadillac converters what they make cadillac converters and battle of it

[@ThirdPlanetRocks]

I don’t think that’s the case - catalytic converters use palladium. $1300+ per ounce. It’s also 4x heavier than aluminum, which is what my silver blob feels somewhat close to
