Caracteres generaux des tonsteins du bassin stephanien de Lons-le-Saunier (Jura); note preliminaire
Keyword(s):
Abstract Study of different claystones in the Stephanian (Carboniferous) deposits of the Lons-le-Saunier coal basin, France, shows that they retain certain features over relatively long distances. The x-ray diffraction pattern, in particular, is often typical of a given claystone. Kaolinite is practically the only clay mineral present. The claystones must have been derived from the soil cover of a continental land area.
