Characterization of the type of kerogen, its relative level of thermal maturity, the fraction of pyrolyzable organic compounds which are free, and the compositions of the bitumen and kerogen. Dominant factor affecting sediments appears to be thermal maturity. Hydrocarbon generation was restricted to within about 10 meters of the shale/sill contacts.--Modified journal abstract.completedGeochemistry of rocks, soils, and sedimentsalterationAtlantic Oceanbitumensblack shaleCape Verde AtlanticCape Verde Risechromatogramsclastic rockscontact metamorphismcoresCretaceousDeep Sea Drilling ProjectDSDP Site 368energy sourcesexperimental studiesgas chromatographygeochemistryintrusionskerogenLeg 41maturityMesozoicmetamorphismNorth Atlanticorganic compoundsorganic materialspyrolysissedimentary rockssillsthermal alterationthermal effectsurn:org.iodp:exp:41urnlargerWorkCitationcampaignurn:org.iodp:exp:41:site:368urnlargerWorkCitationstudyurn:org.iodp:exp:41urnlargerWorkCitationcampaignEnglishgeoscientificInformation-21.2112-21.211217.302417.3024
