GeneralWillem Uytenbogaardt (1918-2012) RIP

30th May 2012 16:24 UTCChris Stanley Expert

Prof Willem Uytenbogaardt, emeritus professor at Delft University of Technology and the Free University of Amsterdam has passed away at the age of 93. Professor Uytenbogaardt, in his days a prominent ore-microscopist, was co-author of “Tables for Microscopic Identification of Ore Minerals” together with E.A.J. Burke. The mineral uytenbogaardtite (Ag3AuS2) was named in his honour.


This is sad news relayed to me by Professor Voncken of Delft University of Technology and I send my sincere condolences to his friends and family and, indeed, the whole of the Dutch mineralogical community.

This is always sad news. Do you know his birthday and month and his birth and death towns so his biographical entry may be updated?

I have the book “Tables for Microscopic Identification of Ore Minerals” by Uytenbogaardt and Burke.


It is a great work ... so much contributed by these two gentlemen!

Identified silver minerals are: native silver and electrum; the sulfides acanthite, argentite (the latter always inverted to acanthite), and members of the Silberkies group; the sulfosalts matildite, miargyrite, pyrargyrite, argentian tetrahedrite, and unnamed Ag-Sb-S and Ag-Fe-Sb-S minerals; the telluride hessite and the selenide naumannite; halides of the cerargyrite group; and the antimonate stetefeldtite. Suspected silver minerals include the sulfide uytenbogaardtite and the sulfosalts andorite, diaphorite, and polybasite. Electrum, acanthite, and argentian tetrahedrite are common, though nowhere abundant. The other silver minerals are rare.



Has there actually been any uytenbogaardite positively identified?
