A map of the sediment thickness (isopach) and occurrence of hydrocarbons is an initial step in identifying the [[petroleum system]](s) of a basin. The figure below shows the total Jurassic to Recent sediment thickness and hydrocarbon occurrences in the GOM basin The hydrocarbon occurrences are concentrated in reservoir rocks that range in age from Jurassic to Pleistocene along the northern margin of the basin in the area over transitional crust and thick salt accumulations. Identification of specific subbasinal depocenters within the area of hydrocarbon occurrences is shown in Figure 4-4. Hydrocarbon types reflect the composition of the kerogens from which they were generated and provide an estimate of the potential number of [[source rock]]s within the area (see Figure 4-5).
