Abstract:
In this chapter, we will report on the amino acids in the total acid hydrolysate of eight sediment samples from Leg 68 Site 502. This site was located on a topographic high at a depth of 3051 meters in the Colombian Basin of the western Caribbean Sea. Four holes were cored at the site by means of the hydraulic piston corer to a maximum sediment depth of 218 meters. The composite section is a virtually continuous, undisturbed sediment record covering almost 8 million years from the Holocene to late Miocene. Age estimates for the section are based on excellent magnetostratigraphic and biostratigraphic records. Four lithostratigraphic units (A, B, C, and D) were recognized, based on differences in color and content of clay, ash, foraminifers, and siliceous microfossils (Prell, Gardner, et al., 1980): A, yellowish brown to light brownish gray foraminifer-bearing (> 10%) nannofossil marl; B, gray to olive gray foraminifer-bearing nannofossil marl with occasional ash beds; C, light gray to dark greenish gray calcareous clay and foraminifer-bearing (< 10%) nannofossil marl; D, pale green to grayish green calcareous, ash-bearing clay with siliceous microfossils. The calcium carbonate content of these sediments increases from about 27 to about 49% from late Miocene to middle Pliocene (about 3.6 Ma) and remains uniform at about 48 to 50% from that time throughout the Quaternary. The eight sediment samples for amino acid analyses came from the third (502B) and fourth (502C) holes at Site 502. Samples ranged in sub-bottom depth from 4.3 to 225 meters spanning time from 0.3 to 7.7 Ma.
