Shortly after the meeting between the 19th and 22nd May in Syktyvkar the Proceedings volume has been published:
Problems and perspectives of modern mineralogy (Yushkin Memorial Seminar–2014) Proceedings of mineralogical seminar with international participation Syktyvkar, Komi Republic, Russia 19–22 May 2014
The Rappenglück et al. contribution condenses the mineralogical evidence of the iron silicides from the Chiemgau impact crater strewn field that has been compiled with invaluable support by Carl Zeiss Microscopy und Oxford Instruments NanoScience.
We remind of the fact that in the beginning of the research on the Chiemgau impact the group of quite experienced local historians and amateur archeologists had detected the metallic iron silicides and, after having been aware of their relation to crateriform structures, had published the possible meteoritic origin of the matter. Investigations and attempts, respectively, to dismiss all iron silicides as industrial waste product, or at least as terrestrial, followed, and they are still spread rumors as for instance by the Bavarian Geological Survey (Landesamt für Umwelt, LfU) which is commented (in German) elsewhere and may be clicked HERE.
Ultimately it is evident that these local historians who later got together with scientists from geosciences, astronomy, archeology and historical scholarship to establish the Chiemgau Impact Research Team (CIRT), are proved right!
