Contemporary analogue of Medieval tramped floors in Romania
Fieldwork in the Eastern part of Romania was conducted within the Czech Science Foundation project Transformation of the Burgher House in the 13th Century (Brno–Prague–Wroclaw). The principal aim of the fieldwork was to describe analogies of Medieval trampled floors for a better understanding of their formation processes, maintenance and abandonment.
Microbial precipitates in old iron ore mines (central Bohemia)
One of the preserved galleries in the former iron-ore mining district of Zdice (35 km SW of Prague) originated between 1950 and 1965. The iron-rich layer, Ordovician (460 million years) in age, was found to be of low thickness and low grade to be economic. The present study of the gallery is focused on presently forming secondary precipitates of iron and calcium compounds. It is likely that some of the precipitates are microbially induced, with a significant involvement of iron bacteria.
