The diagenesis of the loma beds may be seen here to good advantage. Sometimes the chalk forms irregular in thin beds and again after such a thin bed has formed from 3/4 to 1/4 inch thick it minute holes of though settling and or come to look like an intra- formational conglomerate. Once often concretions may devlop, often quite regularly and then of an very irregular concretions will devlope sometimes just in domini most chok around the periphery. These lagna concretions are not of chalk but are of dolomite with a different color and therefore chemical com- position. There 2 pictures behind no tripod. In other thin beds of dolomite the diagenesis is more regular as the entire stone is Kelly, while their kentiels in the darker dolomites. Thus [illegible] The lines represent the white knots.
