Mineralization is hosted in slate and quartzite. For example, sections of the San Andreas ruptured by major earthquakes in and are now relatively quiet, even at the lower magnitudes. On the other hand, some source zones, such as the region off Cape Mendocino and the Mammoth area, have clearly been .

For our detailed sedimentologic analysis, we have selected well correlated turbidites within the Juan de Fuca Channel that is a tributary channel to the Cascadia Channel.

Mendocino Canyon has received little scientific attention; indeed, no detailed bathymetric map could be found for the canyon head.

Two piston cores and a box core have been collected in Mendocino Channel ~70 km downstream of the canyon head [Goldfinger et al., ].These cores contained turbidity current deposits (turbidites) with an average recurrence interval of 34 years during the past. Small scale mining of the deep sea floor is being developed off the coast of Papua New Guinea using robotic techniques, but the obstacles are formidable.

Until recently, scientists had not looked closely for similar landslides off the Southern California coast. Previously known slides in the region are the Goleta slide in Santa Barbara Channel and the Palos Verdes debris avalanche off Palos Verdes Peninsula, each less than half a cubic kilometer in size.

The Bureau of Mines has investigated the occurrence and recovery of byproduct heavy minerals from sand and gravel operations as a means of assessing the nation's resources. Sand samples from 63 locations in central and southern California were treated to yield heavy- mineral concentrates.
