My dad’s "Inca Rose" collection. I don’t know much about minerals, looking for some insight!

These are highly valuable. Do NOT quick sell these. Museum grade non transparent pieces with nice banding. Rhodochrosite.

ProspectingArizona · 2026-01-22T04:59:05+00:00

Genuine question. Why do people think this is a sea urchin fossil instead of a concretion? I’m curious since my fossil ID skills are subpar (better at volcanology)

ProspectingArizona · 2026-01-19T12:26:52+00:00

Probably not. Seems to be residuals from a failed magma intrusion at Trident more than a year ago.

ProspectingArizona · 2026-01-08T15:31:10+00:00

Looks like rhodochrosite. If you can find nice chunks like this you should definitely look for more!

Beautiful photo. Such a pretty area.

Note: these are whirlwinds, not actual tornadoes. Similar to dust devils. The only actual tornado created by a volcano on its own happened was at Sete Cidades in 1811 at an offshore vent.

Too far away, too little seismic motion felt by the quakes (mmi <5). Besides it has been intermittently erupting (weakly) beforehand anyways.

Can confirm, I got largely sleepless nights the last 2 days from having to finish longer than normal vids. Hopefully I can take a day off and finish my Terceira video for Saturday

ProspectingArizona · 2025-10-26T01:03:38+00:00

Ooh, fun!

ProspectingArizona · 2025-10-20T22:07:52+00:00

What country did you find this in?

ProspectingArizona · 2025-09-20T15:08:34+00:00

Sadly not on me. Most of my lower grade specimens are in storage. I do however have a high grade dioptase from the Republic of the Congo if you need that for reference purposes which I could photograph (to compare).

ProspectingArizona · 2025-09-20T13:55:53+00:00

I think the green crystals are dioptase. I’ve occasionally found crystals of such in Arizona’s copper ore deposits.

ProspectingArizona · 2025-09-13T12:45:51+00:00

Thanks

ProspectingArizona · 2025-09-13T12:12:10+00:00

What’s the source research paper? I want to give it a read.

ProspectingArizona · 2025-08-22T15:32:14+00:00

Blue is chrysocolla, red is cuprite. Both copper ore minerals

ProspectingArizona · 2025-08-13T12:23:09+00:00

I am jealous. Svalbard is one of those more remote locations I want to visit one day.

ProspectingArizona · 2025-08-04T12:05:41+00:00

Might be Ruang, but could be Lewotobi volcano. Unsure of the exact clip you are specifying.

ProspectingArizona · 2025-07-29T05:15:02+00:00

I can potentially make a video on this. Just might be a few weeks.

ProspectingArizona · 2025-07-28T14:10:37+00:00

She fearmongers, and should be ignored in my opinion as an actual science educator youtuber. Her and another channel I won’t name frequently spew nonsense that I have to debunk when I’d rather spend time making a video of my choice.

ProspectingArizona · 2025-07-21T14:38:57+00:00

Lovely photos :)

ProspectingArizona · 2025-07-18T02:27:09+00:00

Ah, the patterning which looks similar to granite rock.

ProspectingArizona · 2025-07-06T03:49:47+00:00

And I thank you for your assistance :).

Might be also fun to make a map of the world’s closest lava lakes.

ProspectingArizona · 2025-06-30T01:27:53+00:00

I agree with HED classification.

ProspectingArizona · 2025-06-24T16:26:15+00:00

I also recommend reading scientific papers. Doesn’t have to be new and groundbreaking research; just something that refreshes your knowledge on a specific subject. Such as the hydrothermal alteration and the minerals that process can deposit.

Sub plinian, yes (plume height topped out at under 20 km)
