Monday's Minerals-02/21/2022

It is time to look at some minerals.

Banded Iron Formation consisting of Jasper (red), Hematite (gray), and Yellow (Tiger-eye) from Brookman Mountain, Australia.

Pyrite on black shale. These are found in the spoils from coal mining near Dwight, IL.

Bornite (purplish), also known as Peacock Ore from the copper mines of Butte Montana. The gold color is Chalcopyrite.

Wow - lighting is everything with that first image of the banded iron - that is just amazing. The pyrite is equally interesting with the shapes on the surface and the colors in the bornite are really cool.

 

[Ben Egbert]

Cool. I am really enjoying these colorful displays.

I love seeing these, Doug!

 

[Jameel Hyder]

Very colorful and fascinating. Lee them coming. Enjoying these.

So amazing Doug! It’s so cool seeing all these colors and patterns. The 2nd group looks like butterflies!

I'm glad you enjoy these, Alan. Seeing specimens like these when I was a kid is what drove me into geology as a profession.

Thanks so much, Ben. I'm happy you enjoy these as much as I do.

Thanks, Monika. I am glad that you enjoy these. I have always been fascinated with mineral specimens and believe they are some of the most beautiful objects nature can produce.

Thanks, Jameel. I will keep them coming until I run out of specimens to photograph.

Thanks, Jim. My dad and I used to go pick specimens off of the tailing piles of the fluorite mines at Cave-in-Rock, IL when I was a kid.

Thanks, Oliver. That banded iron formation is a rather unusual one. Tiger-eye is not typically found in this situation. I walked into a rock shop in South Dakota and there were several specimens sitting on a shelf priced way below the typical selling point. Needless to say, I snapped them up.
