(Table 1) Age, total organic carbon, organic matter types, and pyrolysis results from DSDP Leg 84 Holes

Continental slope samples offshore Guatemala contain organic matter derived from both terrestrial and marine sources. 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.
