The stratigraphy of the Formation which is poorly fossiliferous in macrofossils may well be better understood by the study of spores which appear to be abundant in the rocks.

A dark stained fissure occurs in the limestone ofthe Togopi Formation within the study area striking almost perpendicular to the oil-stained band reported previously. A brief organic geochemical characteristic of this limestone fissure is presented here and compared to the previously reported sample. A comparison is also made to a non-stained
