Organic matter occurrences in rock are controlled by both productivity and preservation.  This laminated rock from the Monterey Formation of California has seasonal laminations;  dark layers represent wet season clay from surface runoff that is also organic rich as the marine productivity system peaks during this season due to both nutrients in the runoff-waters and coincident upwelling of nutrient-rich deep water.
