Dow et al.<ref name=ch04r29 /> present a case for a Miocene source rock for the East Breaks 160-161 field, based primarily on the interpretation that the East Breaks 160-161 minibasin is a self-contained [[petroleum system]] enclosed by a salt floor and walls, and thus the hydrocarbons must have been generated from within (see Figure 4-8). Those workers present analyses of kerogens from late Miocene gravity-flow-deposited mudstones, suggesting some potential for oil generation, and speculate that more deeply buried, more organic-rich middle Miocene mudstones may be the source of the hydrocarbons. Taylor and Armentrout<ref name=ch04r93>Taylor, G., S., Armentrout, J., M., 1990, Rock geochemistry and relationships to produced oils from upper Pliocene turbidites, High Island area, Gulf of Mexico: Proceedings, Gulf Coast Section SEPM 9th Annual Research conference, p. 151–161.</ref> analyzed oils and kerogens in turbidite facies at the High Island A-537 field. They speculate that kerogens in Neogene turbidite facies are unlikely to be the source of oils in the A-537 field and further speculate that deeper [[source rocks]] with a strong marine algal fingerprint were more likely sources for the oils.
