The metagabbro-amphibolite sequences in the KTB pilot hole contain intercalations of talc-chlorite-amphibole felses (or “hosbachites”), which show transitional contacts to the adjacent metagabbros. The hosbachites are characterized by relics of a

Subordinate serpentinites in Moldanubian gneisses in northeastern Bavaria were formerly harzburgites to dunites. They contain relics of apparently primary chromite which are similar in composition to chromites in ophiolitic, Alpine-type tectonites as

The contents of silver and mercury in 323 spots on gold grains from seven localities of the Witwatersrand palaeo-placer and Archaean vein deposits from Barberton were measured using an electron microprobe. The objective was to obtain information on t

The geology of stratified sulfide deposits suggests strongly that they formed under low temperature conditions at or close to the sediment surface (P.A. Trudinger and N. Williams, this volume). Today, in such environments, iron sulfides frequently fo

The Schwarzwald (Black Forest) is one of the old mining regions of Germany. Indications of mining by the Romans were found at Badenweiler (Kirchheimer 1976). The oldest document proving mining activities dates from 1028 (Metz 1957c, Schneiderhohn 195
