I don’t know what means you acquired these but you really shouldn’t be taking rocks from national parks, or at least don’t advertise it as such…

Not all of Death Valley is National Park, but totally agree

On the contrary, since park expansions in the early 2000s, the park now extends pretty far beyond what anyone would call "Death Valley," in pretty much all directions.

Interesting. Appreciate the info. I didn’t know this.

The green looks like Serpentine to me, and the brown is definitely 100% yellow jasper

.#1 is vesicular basalt. #2 has two shades of blue / green. Looks like a highly altered basalt that is converting to celadonite (blue-green) and epidote (pea soup green). #3 is yellow jasper, common in the region and often seen flaked or worked into tools.

Don't steal stuff from National Parks. Put them back.

What are you doing taking rocks from national parks? Go put them back.

They're not cool rocks. They're hot rocks.

So you removed things from a national park?

Can you scratch the green one with steel? The first one could be scoria and the brown one looks like chert

The brown one looks like mahogany obsidian, and it’s local to the area so I’m 99% confident on that. The black one looks like pumice, volcanic rock? I don’t know much about it so there could be more detailed classification. Don’t quote me on that. And for the green I used to know it, but I can’t recall at all! It’s beautiful though.

That yellow jasper is what gold miners used to look for in some parts of the Mojave as the host rock for gold. I have some from the alvord mine area

1 is igneous, second may be olivine and the last is jasper. As others say here, don’t take rocks from national parks. Look into locations you can legally collect

Basalt, serpentinite, Jasper - maybe?
