Thomas Witzke - Klaus Thalheim - Andreas Massanek: Minerale mit einer Typlokalität in Sachsen




Almost 100 minerals were described for the first time from a locality in Saxony, from aerugite to zeunerite, among them well-known minerals like stephanite, bismuth and uraninite, or less known ones like brendelite, omphacite and rietveldite. The first descriptions date back to as early as the 1500s, and the most recent minerals covered in this book were recognized by the IMA in 2017. The history of discovery, quotations from historical literature, the development of knowledge from their first description to the present, but also errors, stories about fakes and unexpected discoveries find extensive space in the book. In addition, there are numerous photos of the type specimens that were used for the initial description. Further photos show mostly historical specimens from museums and their labels, but also current new discoveries from Saxony.
In the book further minerals are described, which could have become Saxon first descriptions, but for various reasons did not become so or were redefined with other type locality. An extensive chapter is devoted to minerals that were originally described with Saxon type locality, but were discredited some time ago, and in some cases only recently. Biographies of personalities after whom a Saxon mineral is named or who are related to Saxony complete the book.
Thus, the book offers on about 660 pages a complete overview of all aspects of minerals with Saxon t locality (partly more detailed than on the homepage here).

The book was published by the Bode Verlag in October 2018.

Signs, marks, and inscriptions in mines



             eine Veröffentlichung der Grubenarchäologischen Gesellschaft

At time only in German:
Eingeschlagene oder gemalte Zeichen, Inschriften, Malereien und Tafeln der verschiedensten Art finden sich relativ häufig im Bergbau. Zum Teil dokumentieren sie Vortriebsleistungen, Beginn oder Ende von Auffahrungen, geben Durchschlagspunkte an, dienen der Vermessung, Markierung oder Abgrenzung von Gruben oder Grubenfeldern, dokumentieren besondere Ereignisse, zum Teil sagen sie auch nur "ich habe hier gearbeitet" oder "ich war hier".
Einige dieser Zeichen und Inschriften sind klein und unscheinbar, andere sind sehr groß, auffällig, seit langem bekannt und auf Rissen dokumentiert.

Mit diesem Beitrag soll ein kurzer Überblick über derartige Zeichen, Inschriften, Tafeln und Malereien gegeben werden. Eine vollständige Darstellung ist nicht möglich, schon aus dem Grund, dass es hier noch zahlreiche offenen Fragen gibt, und würde auch den Rahmen dieses Beitrags sprengen. Wesentliche Teile dieses Beitrags sind auch noch im Aufbau befindlich. Der Schwerpunkt liegt gegenwärtig bei den sächsischen und thüringischen Bergwerken, jedoch werden auch eine Reihe von Gruben aus anderen Gebieten in Deutschland sowie aus Niederland, Belgien, Luxemburg, Österreich und der Tschechischen Republik behandelt.
