In two slides the carbonate minerals are more than 90 percent and are thus pure
chemical in origin. It is also observed that the carbonate minerals are more
prominant in the basal part as compared to the upper part. However, no gradual ...

Presence of glauconite in slides which contain chlorite in a very minor amount
also substantiates the writers' view. The view is further confirmed by the fact that
glauconite is present only in the very basal part of the formation. Ore minerals
