Abstract
A detailed heavy mineral study was made of a portion of the Modelo formation in the Santa Monica Mountains, near Los Angeles. It was found that the heavy minerals varied both vertically in the formation and laterally within single lithologic units. Four distinct mineral zones were recognized. These zones transect the lithologic boundaries and the structure of the formation. The cause of the peculiar boundary relations between the mineral zones and the rock units is not clear. Whether or not the mineral zone boundaries are surfaces of contemporaneous deposition remains a moot question.
