The main ore stage of three similar unconformity-related vein systems in the Schwarzwald, SW Germany spanning a period of activity of ~150 Ma, was investigated to understand the details of fluid penetration from overlying sediments/marine environment into the basement, their evolution as well as the processes involved in vein formation. showing fluorite and quartz crystals.

Structures such as hydraulic breccias and hydrothermal veins both form when fluid velocities and pressures are high, which can be achieved by localized fluid transport in space and time, via hydrofractures. 2 Mine (Lucky Strike #2) Thompson, M.

Using this approach, we estimate the temperature gap between, In the Federal Republic of Germany lead-zinc ore and lead ore mineralizations occur in Triassic sandstones in the Buntsandstein of the northern Eifel, above all, in the deposits of Mechernich and Maubach, and in the Middle to Upper Triassic of the Oberpfalz, respectively.

Complemented with available geochronological data from other occurrences, the formation of native metal-arsenide assemblage in Central Europe can be related to continental rifting affiliated with the Mesozoic opening of the Atlantic and Alpine Tethys Oceans (200–100 Ma).

We propose that metamorphic rocks with abundant veins, such as in the Kodiak accretionary prism (Alaska) and Otago schists (New Zealand), represent regions with abundant hydrofractures near the fluid source, while hydrothermal breccias are formed by the large fluid bursts that can ascend the crust to shallower levels.

When hydrofractures are activated due to low permeability relative to fluid flux, many hydrofractures form that do not extend through the whole system. (1868): The Mineralogist's Directory. In contrast, it occurs systematically later with increasing distance to the rift axis – namely at ~200–130 Ma in intermediate (Schwarzwald, Odenwald, Spessart) and ~ 140–86 Ma in distal (Erzgebirge, Harz) positions to the main rift axis.
