The Poci bauxite deposits in western Henan, China, are hosted in the lower member of
Upper Carboniferous Benxi Formation, unconformably overlying upon the paleokarst …

Since the 1980′ s, more than 15 geothermal wells have been drilled in the Upper Rhine
Graben (URG), representing more than 60 km of drill length. Although some early concepts …

Defining the fracture network and the active fluid pathways are fundamental to
characterizing a fractured reservoir. With this goal, we chose the Saint Pierre Bois quarry …

Above two billion tons of bauxite were formed during the exposure of the North China Craton
(NCC) in 445–300 Ma. Mineralogical, geochemical, and isotopic analyses of karstic bauxite …

The extraction of lithium from geothermal brines is one of the most promising fields for
mining this important element, which plays and will play an increasingly important role in the …

Borehole studies of the Soultz-sous-Forêts granite are dedicated to deep geothermics. The
hydraulic properties of the reservoir are mainly controlled by the occurrence of some altered …

This richly illustrated book presents Germany's geological evolution in the context of the
Earth's dynamic history. It starts with an introduction to Geology and explains the plate …

Identification of magnetic minerals using the temperature dependence of magnetic
susceptibility in low field (κ–T) combined with optical microscopy, microprobe, X-ray …

The formation of clay minerals in volcanic successions follows various evolutionary trends,
the understanding of which is crucial for estimating the age of volcanism and the prospecting …

Two geothermal wells, GRT-1 and GRT-2, were drilled into the granite at Rittershoffen
(Alsace, France) in the Upper Rhine Graben to exploit geothermal resources at the sediment …
