The Luxembourg Sandstone (French: Grès de Luxembourg) is a geologic formation in Luxembourg. It exists along the eastern margin of the Paris Basin. Sandstone units continuous with the Luxembourg Sandstone also occur in France. It is Early Jurassic in age. It predominantly outcrops in a belt extending through south-central Luxembourg. It up to 100 metres thick and predominantly consists of carbonaceous poorly cemented sandstone and sandy limestone[1][2][3][4]
