In period of tectonic relaxation, sharp regression can be observed in Sidi Bettach Basin.

These basins were formed in a structural context of transtension from Famennian to Visean and transpression during late Visean and Namurian with the formation of glidding and tectonic nappes.

Filtering techniques such as horizontal gradient, upward continuation and Euler deconvolution were used to map structural lineaments in NEM. The Cannes de Roche Formation unconformably overlies the Malbaie, and resembles many other Carboniferous deposits in Maritime Canada. Huit couches principales de charbon se développent dans ce bassin paralique, pendant les phases de rétrogradation de faciès distaux sur des faciès proximaux. These later faults have allowed the emplacement of late Hercynian granitoïds.A palaeogeographical and structural reconstruction comparable to that established in the rest of the Moroccan Meseta is proposed.Three African examples of coal occurrence vary greatly in geodynamic conditions for peat (coal) development.In the Anambra basin, near Enugu (Nigeria), Maastrichtian coal bearing strata developed after settling of the prodeltaic type Enugu Shales. The average nitrate levels are in the range of 300mg/l while those chlorides are of the order of 418 mg/l.The analysis by emission spectrometry with inductively coupled plasma (ICP) showed mean concentrations of calcium in the range of 170mg/l,340mg/l for sodium and 309mg/l for magnesium while contents of Al, As, Cd remain negligible or even below the detection limit.The results of physico-chemical analysis of groundwater level in the province of Jerada show high pollution level in the region.Jerada coal mine is located in north east of Morocco, and closed in late 2001.Today the quantity stored is about genus Verbascum L. fccording to the structure, way of growth and branching of the fl owering axes an be divided into three groups: multiple complex dichasium, multiple dichasium with monohasium and complex monohasium. Depending on the regional setting, different relationships exist between marine transgression and the respective effects of tectonics and of sea-level changes: in western Europe, effects of the glacial processes in Gondwanaland are partly balanced by the late compression in the Hercynian belt during Moscovian. In this transition zone, thick coals attain a relatively high degree of lateral continuity and are usually low in sulfur. However, most important seams in the Appalachian area are in the transitional zone between these two environmental facies. The sequence SVI is Asselian, Autunian and Nealian. The sequence SV is Gzhelian–Orenburgian, late Stephanian and Virgilian. developed in the region in order to assess the quality of these waters and to estimate the risk of contamination. After numerous lithologic and paleontologic investigations, a precise biostratigraphic scale was built, especially by foraminifers for Morocco to date limestones in platform, but also turbidites because carbonate and detrital sediments are mixed in platform and basin.
