Handpolishing metal ores

- Chromite, limonite, pyrite, and one unknown.
(1) The chromite was found in Baltimore City's harbor. It was probably imported for steel production. I also show some chromite crystals from a "placer" in Delaware County, PA.
(2) The limonite pseudomorph is from Chester County, PA. Also called a devil's die.
(3) The pyrite is from railroad ballast in the Baltimore area. Could be local. (It could also be chalcopyrite. Both are called fool's gold. That said, they can contain trace amounts of real gold.)
(4) Any ideas what the unknown metal ore is in that last specimen? If so, please comment. Thank you!
Nice specimens
Can you make a close up of those
Tiny iron like specimens in that reaction tube
They look like the powder that you can find in a bullet
btw you need to search up the stuff i told you in the vid from 1month ago
So you can know what that stuff is
And maybe can be usefull for your later finds
Thank you!
I made a photo at 10x magnification of the small faceted pieces of chromite but I see no way to attach that here.
In any case, they are small chromite crystals found at a known placer in Pennsylvania. A placer is where a mineral is weathering out of bedrock, mostly by water erosion.
In this case, the placer is in a serpentine barren. We have a number of such barrens in the mid-Atlantic area, though unfortunately most have been built over.
Chromite is commonly found in serpentine barrens. In fact, chromite was mined in the Baltimore area until better sources were discovered in Turkey.
As for meteorites, I will look into those!
By the way, have you looked into micrometeorites?
I myself have found numerous tiny spheres (the size of very small ticks) at roof gutter spouts and while panning for gold. Of course, such micrometeorites are falling down to earth all the time. We have all been hit by one or more without realizing it. Roofs are a great place to look. (I myself used a magnet inside a plastic bag to collect them.
But...since then I learned that tiny spheres of metal are everywhere and mostly originate from human industry. The only way to tell if something is a true micrometeorite is with a high powered microscope. I don't have one of those, and I don't want to send specimens away for analysis each time. So I have given up on searching for micrometeorites for now. But you sound like a candidate for that!
@@spiritualpathseeker Of mms ar many types More Specific 5 types
I know 2 of those types Barred Olivine
And Iron
I found 15-16 Iron mm
And one Barred olivine
Begause of my clumsy hands have i lost
1 barred olivine Do you know about John Larsons Work yet
I published many pictures of mm
Mostly barred olivine (btw dont send any
Samples) I know allot about that subject
And i have no good instruments for that i only use my 56euro microscope
and i use my headlight to see the tiny microscopic samples.
