Marklite

Marklite is a hydrated copper carbonate mineral named after Gregor Markl, a German mineralogist at the University of Tübingen.^[3] Markl found the type specimen of marklite in the dumps of the Friedrich-Christian mine in the Black Forest Mountains in southwestern Germany.^[4] Markl specializes in crustal petrology and geochemistry and has studied the hydrothermal ore deposits of the Black Forest area.^[5] Jakub Plášil of the Institute of Physics at the Academy of Sciences of the Czech Republic and colleagues identified its structure.^[6]
