This metadata file accompanies a report about the resultsof a study of the heavy minerals insamples collected from beaches and seafloor locationsin the Palos Verdes margin, south of the Los Angeles area,California. Samples were collected from 11 beach locationsbetween Hermosa Beach and Point Fermin, California. Boxcores were subsampled for 26 offshore samples.MINSPLSMC is an Arcinfo point coverage of the locations ofthe samples.
Human intervention in the hydrologic basin of the Colorado River has eliminated water discharge and sediment supply to the river's mouth and its delta. After not, vert, similar95 years of applying strong flow control policies, the previous sedimentary budget in the delta has changed, the delta now being entirely exposed to the hydrodynamic forces in its basin. In order to assess the anthropogenic impact of water diversion on deltaic sedimentary processes and short-term delta geomorphic evolution, textural and mineralogical analyses were performed on 68 sediment samples collected from the river, estuary, beach, continental shelf, delta plain and desert. The results show a consistent NE to SW textural gradient on...
