Perspective diagrams showing geochemical abundance of silver, lanthanum, molybdenum, nickel, vanadium, yttrium, and zinc in the Nabesna Quadrangle, Alaska Perspective diagrams showing geochemical abundance of silver, lanthanum, molybdenum, nickel, vanadium, yttrium, and zinc in the Nabesna Quadrangle, Alaska
The seven perspective diagrams on this sheet show the distribution patterns of silver, lanthanum, molybdenum, nickel, vanadium, yttrium, and zinc in stream sediments in the Nabesna quadrangle. The diagrams portray the distribution and abundance of the elements and their relation to some of the geologic units (Richter, 1975) in easy-to-visualize, 3-dimensional perspective.
Photointerpretive map of landslides and surficial deposits of northernmost Napa County, California Photointerpretive map of landslides and surficial deposits of northernmost Napa County, California
This map shows various types of landslide deposits, scarps, and related topographic features, in addition to other types of surficial deposits, in northernmost Napa County, California.
