Abstract
Maps showing the distribution of anomalous amounts of selected elements found in more than 1,600 stream-sediment and more than 1,500 rock samples have been prepared form results of semiquantitative spectrographic analyses. The samples were collected in the Eagle quadrangle, east-central Alaska, in the summers of 1968, 1969, 1970, and 1971.
Figure 1 is a map showing localities for all stream-sediment samples analyzed and indicates by symbols those containing anomalous amounts of one or more of the following elements: gold (Au), silver (Ag), arsenic (As), bismuth (Bi), copper (Cu), chromium (Cr), molybdenum (Mo), nickel (Ni), lead (Pb), antimony (Sb), tin (Sn), tungsten (W), and zinc (Zn). Figure 2 shows the localities for analyzed rock samples and indicates those containing specified amounts of the same elements as selected from the stream-sediment samples.
Maps similar to these which showed the distribution of anomalous amounts of selected elements in stream-sediment and rock samples from the Eagle quadrangle were compiled in 1971 and issued as a U.S. Geological Survey open-file report (Foster and Yount, 1971). The maps of this report are revised from the open-file maps to include the sampling in the summer of 1971.
