Article
The site selection procedure for a high-level radioactive waste repository in Germany is based on the Repository Site Selection Act (StandAG, 2017), which comprises three phases. In phase 2, the Federal Company for Radioactive Waste Disposal (BGE) will conduct surface exploration. Based on the exploratory findings, the further developed preliminary...

Pervasive alteration of basaltic oceanic crust by heated seawater at greenschist facies conditions produces two contrasting hydrothermal rocks. “Spilites”, consisting of chlorite + albite + quartz ± actinolite ± epidote, occur typically with regional extents. Locally spilites are metasomatically transformed to “epidosites” consisting of epidote + q...
Article
The antimoniferous vein-mineralization in the Schleiz and Greiz area, eastern Thuringia, are bound to NE-SW striking Variscan fault zones along the margins of the Berga Antiform. The Sb-Pb-Zn ores form massive sulfide-sulfosalt-quartz±carbonate veins, breccias or stockworks within Ordovician and Silurian metasedimentary units, Devonian metabasalts...

Most rare earth element deposits form from magmatic fluids, but there have also been discoveries of heavy rare earth element (HREE)– enriched hydrothermal xenotime deposits within sedimentary basins. As xenotime is notoriously insoluble, the question arises as to whether these lesser-known deposits form at typical basin temperatures or by influx of...

The antimoniferous vein-mineralizations in the Schleiz and Greiz area, eastern Thuringia, are bound to NE-SW striking Variscan faults zones along the margins of the Berga anticline. The Sb(-Au, Ag)-ores form massive sulfide-sulfosalt-quartz±carbonate veins, breccias or stockworks hosted by Ordovician and Silurian metasedimentary units, Devonian met...

Hydrothermal seafloor alteration is best preserved in obducted oceanic lithosphere. Among the alteration types in the basaltic crustal section of ophiolites are rocks which have been completely altered to epidote + quartz ± titanite ± Fe-oxides, so-called epidosites. These rocks have been interpreted to form within the base of hydrothermal discharg...

A 3-stage magmatic-hydrothermal evolution of the Mt. Tinstone pegmatite is reflected by the mineralogy and fluid inclusion composition. Fluid inclusion data of early mineralisation (e.g. spodumene) presenting a high salinity magmatic fluid (18-14.4 wt.-% CaCl2 eq), trapped at high temperatures (>450 °C) (stage A). Ta-Nb-Sn oxides crystallised and f...

Dieser Bericht liefert eine Übersicht über die Goldführung sächsischer Sand- und Kieslagerstätten. Hierzu wurden durch das LfULG 26 aktive Sand- und Kieslagerstätten in Sachsen ausgewählt. Aus diesen Lagerstät-ten wurden in Begleitung durch das LfULG zwei Typen von Proben gewonnen und bearbeitet – (i) Großproben des geförderten Rohmaterials und (ii...

Project
The goal is to achieve a better understanding of the ore forming processes of fault zone hosted Sb-Pb-Zn mineralizations in the Eastern Thuringian Shist Belt.
Project
A multidisciplinary project aiming to better understand sub-seafloor hydrothermal systems recorded in the Oman-U.A.E. ophiolite.
