The Chemistry of the Clay-Size Fraction Across the Oldman-Bearpaw Contact of the St. Mary River Section [Abstract]

R. N. Farvolden

The clay-sized fraction of samples collected across the Oldman-Bearpaw contact of the St. Mary River section were analysed. The Na2O, K2O, P2O5 and total iron analyses show a break at the contact between the non-marine and marine beds. Other predicted clay chemistry changes do not occur in this section because the normal clay diagenesis was masked and the system was upset by fall-out of volcanic ash.

The investigation shows that the method of rapid silicate analysis can be used for certain geologic studies but the results are not as reliable as those obtained by conventional methods.
