Results from a Study of Recently Deposited Organic Matter in Sediments of the Santa Barbara Basin
Abstract
A small diameter subcore of a larger box core collected from the Santa Barbara Basin (Lat. 34 deg 13.53' N, Long. 120 deg 03.51' W) yielded samples from which organic geochemical studies were conducted. The samples were obtained under a blanket of nitrogen at approximate intervals of 2 cm. The intervals were 0-2, 2-4, 4-6, 8-10, 10-12, and 14-18.5 cm. The isolated samples were subjected to a detailed analytical scheme shown in Figure 1 to characterized the organic matter in the upper sedimentary layers of the basin. The explicit goal of this project was to examine downcore changes in the nature of the organic matter in order to delineate changes which might be ascribed to early diagenesis and to relate these diagenetic changes to sediment physical properties and clay microfabric. The results presented below demonstrate a detailed organic geochemical investigation of the core sections which involves analysis of both the bulk sediment and the lipid extracts of the sediment. To date, these are the most comprehensive analyses performed on sediments from the Santa Barabara Basin.
