Upper Pleistocene samples are generally amorphous-rich, with TOCs averaging 2.4%. Pliocene and Miocene sediments contain varying amounts of terrestrial material that increase in proportion down toward the base of the slope. TOCs average 0.93%. The samples are currently immature for the generation of liquid hydrocarbons.Supplement to: Gilbert, Deborah; Cunningham, Robert (1985): Organic facies variations in sediments from Leg 84, off Guatemala.
