Nov 2014Re: Named pseudomorphsReply from Dmitriy Belakovskiy in Mineralogical Classification.I wonder that a few common pseudomorphs not memorizes still in this thread:
GLENDONITE - calcite after ikaite

Also some names not listed as the names of pseudomorphs but at list in most cases those are pseudomorphs.
A few of them are:

Mar 2010Re: Location information neededReply from Dmitriy Belakovskiy in Identity Help.Hi John, Sergey and Ron !
Sometimes (rarely) you can find that kind glendonite at Olenitsa or other White Sea coast locations, however most likely this specimen originated from Taymyr Peninsula. One of most famous locations at that area is: Bolshaya Balakhnya River about 10-12 km up from the ...

Reedmergnerite bearing quartz from Darai-Pioz looks very different. ...
Jun 2009Re: Cleaning Russian staurolitesReply from Dmitriy Belakovskiy in Techniques for Collectors.I would preffer matrix specimens also however if you really need to remove muscovite mica schist from staurolite the water gun would be much more usefull. The matrix for most of staurolites from Keivy at Kola Peninsula is not hard (it's mica). Another thing is that rather often when you cleaning ...
