Geophysical investigations of Mountain Pass, California, were conducted as part of an effort to study regional crustal structures as an aid to understanding the geologic framework and mineral resources of the eastern Mojave Desert. The study area encompasses Mountain Pass, which is host to one of the world’s largest rare earth element (REE) carbonatite deposits.

Multibeam bathymetry shown in the spectrum from red (shallower) to blue (deeper) for depths greater than 200 m across the head of Astoria Canyon. The land and continental shelf are shown in grayscale slope shading where darker colors represent steeper slopes.  The modern Columbia River is far right.

The AVM-measured velocity used to index mean velocity can be the line velocity from one acoustic path or from multiple acoustic paths.

The AVM measures the average water velocity along the acoustic path (VP, figure 1); then computes the "line velocity," the velocity component parallel with the average downstream flow line.
