 Posted: Nov 27, 2010 19:01 Post subject: New Manganite in the collection |
|
|
Hi folks,
yesterday i was very lucky to finally acquire a specimen of a species and locality that had been on my list for long time - i had a nice example from there before but this one got me a bit on cloud no. 9. Encouraged by Joan i will post it here and share with you although the quality of the pictures is quite poor, don´t have my regular camera with good macro capabilities here .. but it gives the impression of this nice Manganite from Ilfeld, Harz Mts., Germany, the type locality..
Size is 12.5 x 10 x 8 cm.
Hope you enjoy
cheers
Roger
P.S. the specimen needs some professional cleaning still and maybe some preparation .. i will keep you updated!

Nice classic stuff, Roger! Congratulations. The Baryte adds the full paragenesis touch. As I mentioned elsewhere, you will enjoy the monographic article on Ilfeld in the current issue of the MR.
Looking though your other specimens, I also like the Panasqueira ferberite with siderite and apatite. Wasn't this specimen features in Le Regne Mineral vol 43 a few years ago?

Hi Joan,
no i don´t think so ... i took the photograph last year and i have this specimen since the mid 1980s ... but would have been nice ;-) ...
It is one of my favourite collection specimens and i never regretted that i had to pay quite a lot of money for it as a student then...
The manganite looks terrible in the picture unfortunately .. better in person,
cheers
Roger
P.S. a friend of mine in Mainz is a MinRec subscriber so i will have the chance to read the Ilfeld article next week or so..

Roger, A friendly warning. I got a similar specimen a number of years ago, only on mine most of the crystals had their terminations covered by the Baryte. I figured that I could chip away the Baryte to reveal the crystal terminations. However, I soon learned that the Baryte was there first - the manganite crystals had grown into the Baryte and consequently lacked well-formed terminations. So proceed carefully!

Hi Pete,
thanks for the warning. On this specimen quite some perfect manganite terminations are seen peeking out of the baryte and also from the side the terminations under the cover are visible. But i won´t do any preparation and cleaning by myself but show it to an absolute specialist who has done some miracles on other specimens of my collection as well as on other superb specimens from fellow collectors. If he says "no" then only some cleaning will apply and i will leave it as it is ... it is though a quite decent one as it is now,
cheers
Roger

Hi all,
a new classic in my collection. Not the aesthetic killer, but quite a rare one: Staffelite from Steinbach near Hadamar, Hesse. Size is 10.5 x 8 x 4 cm. It comes from the K.S. Freiberger Mineralienniederlage and has a nice late 19th century label. This Staffelite occurrence is approx 10 km away from the "type locality" Staffel.
Cheers
Roger
