Schwarze Crux, Vesser, Suhl, Thuringian Forest, Thuringia, Germany
Schwarze Crux, Vesser, Suhl, Thüringer Wald, Thüringen, DeutschlandAncient iron mine.
Lenticular layers of magnetite ore are intercalated in the upper part of a Cambro-Ordovician bimodal magmatic sequence. The ore bodies and the rocks are positioned within the exo contact of the younger Hercynian Hauptgranit intrusion.
Nearly all minerals of the main pregranitic ore body assemblage underwent pre-intrusion cataclasis. The Fe of the orebody was probably enriched during volcano-exhalative processes of early Paleozoic magmatic arc activity.
