The last field trip at 2016 (12-13th November) was organized to Tertiary deposits of the Krušné hory Mts. (Erzgebirge).
First day was in schedule visit of locality Valeč with nice samples of hyalite in pyroclastics and tuffs of Doupovské hory Mts. Then we moved to visit Sokolov brown coal basin, where we’ve seen active quarry Družba, ongoing recultivation on quarry Medard-Libník and sand quarry Erika with important sedimentary profile of Starosedelské series of strata. On the way to Boží dar village, where we slept, we stopped at the heap of abandoned copper mine Helena near Tisová (Kraslice).
Second day we moved more on the northeast to visit active phonolite quarry Mariánská skála in Ustí nad Labem city with nice samples of zeolites (natrolite) and then looked at the pseudokarst fluorite cave on the Děčínský Sněžník Mt. exposed thanks to fluorite mining.
Seven Chapter members participated on this excursion led by Mgr. Jan Bubal.
