About StudtiteHide

Formula:
[(UO2)(O2)(H2O)2] · H2O
Colour:
Very pale yellow to yellow
Lustre:
Waxy
Crystal System:
Monoclinic
Name:
Named in honor of Franz Edward Studt (or Stüdt) (30 November 1873, London, England, UK - 3 July 1953, Holborn, England, UK), geologist for Tanganyika Concessions Ltd. He prepared an important geological map of Katanga, published in 1913.

Dinah Pantic writes in http://www.mindat.org/mesg-7-192418.html. "Frank Edward Studt was my grandfather. He was trained as a metallurgist and graduated from Imperial College in London about 1898. He was English and his parents originally from Germany. After graduating he worked in the Belgian Congo for about 20 years for a Belgian company. I have many of his original diaries from this time."
A rare secondary uranium mineral containing a peroxide group in its crystal structure.
May dehydrate to metastudtite.
