The Schistes bitumineux (French for Oil shale/Bituminous shale) is an Early Jurassic geologic formation in Bascharage, Luxembourg that is located within an oil shale, hence the name.[3][4]
This formation may be part of the larger Sachrang Formation,[5] which also outcrops in Luxembourg, among other countries. The type locality is the Edward Steichen Industrial Zone near Bascharage and it is part of a near-continuous layer of hard, finely laminated, micritic carbonate nodules.[2]
The Schistes bitumineux underlies the middle Toarcian Marnes à Bifrons Formation,[1] which outcrops in both Luxembourg and France.
