The geology and metallogeny of base steel sulfide deposits in Europe, Africa and Australia used to be the subject of the DMG-GDMB-SAG Joint assembly held in Aachen (FRG), September 16-19, 1985. Divided into components, the awarded papers conceal the outline and interpretation of sediment-hosted in addition to volcanic-sediment-hosted and volcanic-hosted copper-zinc-lead (gold-silver) deposits. the current compilation is an summary of present learn actions and effects on copper-zinc-lead deposits in classical mining districts contemplating geological, lithological, geochemical and tectonic parameters of ore formation. Even during periods of depressed steel costs, base steel sulfide deposits nonetheless stay essentially the most beautiful mineral exploration pursuits. This wide assessment presents important info to researchers and explorationists.

Based on the geochemistry of mafic metavolcanics (Okrusch et al. 1985), and from the metallogenetic point of view there seems to be evidence that parts of the Mid German Crystalline Rise, which represents the northernmost part of the Saxothuringian zone, could be referred to an ensialic island arc oflate Proterozoic to early Paleozoic age.
