Abstract

An extensive X-ray diffraction investigation of Keuper Marl samples from the English Midlands shows the existence of both chloritic and interlayered chloritic clays. Chemical experiments show that the interlayer component of the chloritic phase can be removed. This suggests that the 'chloritic materials of unusual type', known since the early 1950s to exist in the Keuper Marl, represent chlorite-montmorillonite intergrades. The mineralogy of any sample identified by an X-ray investigator, is influenced by the completeness of the chlorite interlayer. Since the amount of interlayer material is variable any 'absolute' differentiation between species is difficult.
