Samples were collected from 11 beach locations between Hermosa Beach and Point Fermin, California. Box cores were subsampled for 26 offshore samples. MINSPLSMC is an Arcinfo point coverage of the locations of the samples. Purpose: Heavy or high-density minerals in the 63-250-um (micron) size fraction (very fine and fine sand) were analyzed from beach and offshore sites to determine the areal and temporal mineralogic distributions and the relation of those distributions to the deposit affected by effluent discharged from the Los Angeles County Sanitation District sewage system.
