Abstract
With regard to drinking and industrial water supply and to mining unwatering, the stratum of Lower Sands-tones of the Trias in Lorraine is one of the most exploited aquifers in this area. The stratum is limited to the north and to the east by the outcrops of the Trias, to the west by an arbitrary line referring to a mineralization rate above 1 g/l, to the south by the Morvano-Vosgean Shelf.
The stratum is extending on hundreds of meters in depth between the crystalline formations of the base or of the Permian argillaceous standstones and the shelly sandstone of the lower Muschelkalk.
The stratum is then confined and its flow runs in general south-north, still with some local variations almost due to collectings.
The reservoir shows a strong heterogeneity which can have a qualitative influence.
