As my August 1, 2019 book deadline draws near, I will not be posting as much at this site. Instead, consider following me on Instagram, from your smartphone or desktop.
My Instagram account is fun and easier for me to do than blog posts. Thanks!
I had said I would send a photo of one I was taking and a little story.
The Ludlockite is a piece I had only read about in a big “Worlds Best Minerals Book we have. It was a piece that a mineral dealer had seen on a porch of a guy in Namibia that sold specimens from the Tsumeb Mine, one of the most famous mines in the world.
The piece on the porch was being used to hold open the screen door. The dealer asked if it was for sale. The guy sold it to him and he sent it right off to his US business and it turned out to be a new mineral and that one chunk on the guy’s porch was all there was.
I had no idea when I saw one for sale for $10, the piece I took the photo of, that it had been discovered in the mine after that first piece was studied. They traced the associated minerals with it and found the place in the mine it had come from.
More was brought out but it was never very common. I got this one for so little and am very happy with it, as much for the story as the piece and as pretty as it is.
The other two I took photos of today too. The Ludjibaite is a rare species and I paid a bit more for the piece, $45 but it is very nice.
The last one of Ludlamite from Mexico we got many years ago and I paid only $10 for it as well and it is a well crystalized piece.
So, that is my recent material.
Now to post them on Mindat.org
Ludjibaite with Pseudomalachite 4mm fov Shituro, Katanga Prov. D. R. Congo (Blue)
Ludlamite 7mm fov Santa Eulalia, Chihuahua, Mexico (Green)
Ludlockite, Germanite, plus 5mm fov Tsumeb Mine, Namibia (Red)
More on the famous Tsumeb mine comes from this text at Mr. Kerry Day’s excellent website, he being the owner and proprietor of KAYGEEDEE MINERALS, a Canadian vendorship devoted to the mineral collecting hobby. He was an economic geologist/mineralogist/SEM-EDS operator for many years. “Selling off my vast collection of mineral specimens, gemstones and lapidary rough has become my retirement hobby.”
It’s a truly fascinating site that I recommend you visit immediately, for a sensational trip around the world while staying right at home. Thousands of great pictures.
TSUMEB MINERALS – Last updated April 12, 2019
The Tsumcorp polymetallic ore deposit was a near vertical ore pipe located near the town of Tsumeb, Namibia. A unique feature was three oxidation zones at various depths – the result of groundwater flow. The combination of oxidation(s) and unique chemistry created a vast suite of well crystallized minerals that are treasured by collectors worldwide. Unfortunately, mining ceased in the 1990s but neighboring ore pipes are now being explored/mined.
