Special issue of Applied Geochemistry on Environmental impacts of mining and smelting

We have co-edited a special issue of Applied Geochemistry devoted to Environmental impacts of mining and smelting. Some of our research has also been published in the frame of this special issue: (i) Kříbek B., Majer V., Knésl I., Keder J., Mapani B., Kamona F., Mihaljevič M., Ettler V., Penížek V., Vaněk A., Sracek O.

New isotope lab is here!

Opening of new isotope lab equipped with a Thermo-Scientific Neptune plus MC-ICP-MS and two mass spectrometer for the analysis of stable isotopes (IRMS MAT 253 a Delta V Advantage) took place in February 10, 2016 after several months of preparations. The equipment purchase was funded by EU projects (Operational Programme Prague – Competitiveness, Project No. CZ.2.16/3.1.00/21516 and OP VaVPi project CZ.1.05/4.1.00/16.0347).

Collaboration with archeologists on early medieval slags

First detailed mineralogical investigation of early medieval slags indicated that in the second half of 12th century, large metallurgical complex, where silver production based on cupellation process, has been active. Our Pb isotope analyses of smelting remains suggest that Pb needed for the cupellation originated probably from mines in Poland. Ettler V., Johan Z., Zavřel J., Walisová M.S., Mihaljevic M., Šebek O.
