“…The effect of these phenomena on the degree of coalification is also known from other European and world basins (Hower and Gayer, 2002). For instance, the influx of heat in front of an advancing orogenic front as an essential factor influencing the rank of coal has also been reported from the Northern Eifel, Rhenisch Massif, Germany (Ribbert and Vieth, 2005), Ruhr basin, Germany (Littke et al, 1994) or from the South Wales Basin, Great Britain (Gayer et al, 1998).…”

The degree of coalification is an essential parameter influencing the quality of coal reserves. Modelling of the development of this parameter in the Czech part of the Upper Silesian Coal Basin (Carboniferous, Mississippian to Pennsylvanian -Lower Namurian to Westphalian A) revealed the distribution of coalification within the basin in all its stratal units. The grade of coalification was found in principle to be similar but its intensity in general decreases upwards into the hanging wall. Because of different areal extents of individual stratal units the degree of coalification is demonstrated on the oldest and areally most extensive unit -the Petřkovice Member. The studies and their results presented in this paper are based on more than 29,000 analyses of the dry and ash-free volatile matter (V daf ) in coal samples from surface and underground boreholes drilled in the years 1946 -2000. Three zones of enhanced coalification were distinguished: the Ostrava-Příbor Zone, the Rožnov-Frenštát Zone and the Příbor-Těšín Zone. These zones were found to correlate fairly well with the occurrence of gas deposits confined to the weathered Carboniferous rock massif or its mantle. Consequently, the degree of coalification does not only determine the quality of coal reserves but may also be used as an auxiliary tool in the search for gas deposits in coal basins.

“…Published R max values for the Upper Rurberg Unit range from 4.5% (Vinzelberg 2002) to 5.44% (von Winterfeld 1994), 5.5% (Ribbert & Vieth 2005) and 5-6% (Fielitz & Mansy 1999;Oncken et al 1999). The relationship between vitrinite reflectance and temperature has been demonstrated by Hood et al (1975) and Bostick et al (1979).…”

In the frontal part of the Rhenohercynian fold-and-thrust belt (High-Ardenne slate belt, Germany), two successive types of quartz veins, oriented normal and parallel to bedding respectively, are interpreted to reflect the early Variscan compressional tectonic inversion of the Ardenne-Eifel sedimentary basin. Fracturing and sealing occurred in Lower Devonian siliciclastic multilayers under very low-grade metamorphic conditions in a brittle upper crust. A geometrical and microthermometric analysis of these veins has helped to constrain the kinematic and pressure-temperature conditions of both vein types, allowing the reconstruction of the stress-state evolution in a basin during tectonic inversion. It is demonstrated that bedding-normal extension veins, which developed under low differential stresses and repeatedly opened and sealed (crack-seal) under near-lithostatic fluid pressures, reflect the latest stage of an extensional stress regime. Bedding-parallel veins, which developed at differential stresses that were still low enough to allow the formation of extension veins, cross-cut the bedding-normal veins and preceded the regional fold and cleavage development. These veins show a pronounced bedding-parallel fabric, reflecting bedding-normal uplift and bedding-parallel shearing under lithostatic to supra-lithostatic fluid pressures during the early stages of a compressional stress regime. This kinematic history corroborates that fluid overpressures are easy to maintain during compressional tectonic inversion at the onset of orogeny.
