Maps showing drift patterns along the north-central Texas coast, 1973-1974 Maps showing drift patterns along the north-central Texas coast, 1973-1974
An investigation of the rates and directions of drift in the northwestern Gulf of Mexico was initiated in January 1970 as part of a program to study depositional processes and sediment movement off the southern Texas coast. The first phase of that program, a study of coastal drift off south Texas, was reported by Hunter and others (1974). They reported on a three-year program of seasonal...
Maps showing maximum earthquake intensity predicted in the southern San Francisco Bay region, California, for large earthquakes on the San Andreas and Hayward Faults Maps showing maximum earthquake intensity predicted in the southern San Francisco Bay region, California, for large earthquakes on the San Andreas and Hayward Faults
This map shows maximum earthquake intensity predicted at specific sites using the empirical relations derived from the reliable 1906 intensity data (figs. 3 and 4; see text). The numbers 4-0 correspond to letters A-E, respectively, of the San Francisco intensity scale. The predicted intensity value shown for each site is the maximum of those predicted for the site assuming that a large...
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.
