Abstract:
A study of the stratigraphy, lithology, and clay mineralogy of the Morrison formation is described. The geologic work was done in the Black Hills area, where four stratigraphic sections of the Morrison formation were examined, measured, and sampled, in detail.
The clay minerals were identified by the X-ray diffraction powder method. It was found that illite is the predominant clay mineral present in the formation. Kaolinite is abundant, and montmorillonite is rare.
It is concluded that there are various clay-mineral assemblages within the formation. They are of local significance only, and can not be used as a basis for subdividing the formation in this area.
The clay minerals are used as indicators to interpret a tentative environment of deposition.
