Experiments were carried out to determine the extent of preservation and the extent of conversion to pheophytin, of chlorophyll dissolved in oil, during sedimentation with illite, montmorillonite, and kaolinite in fresh and salt water and under varying conditions of pH and redox potential.

The major controlling factor in these systems was pH and it was found that at high pH values chlorophyll was extensively destroyed and as acid conditions were approached the preservation of total pigment was good with increasing conversion to pheophytin. Both the conditions of pH and redox potential favorable for the formation of petroleum and the preservation and conversion of chlorophyll were found to be coincident.
