Description:
The author has identified the following significant results. Preliminary results of examinations of the ERTS-1 imagery are: (1) although the interpretation was accomplished on a scale of 1:1,000,000, X2 magnification was necessary for greater detail; (2) channel 7 of MSS imagery gave better contrast for detecting geological features; (3) topographic features located south of Phoenix easily identified from surrounding alluvium; (4) granites and granite gniesses in vicinity of Newman Peak cannot be subdivided from examing ERTS-1 imagery; (5) one major lineation, made up of many parallel lineations, is noticeable just north of Lake Pleasant that extends for approximately 100 miles in a northern direction; (6) most of the regional lineations fall into three general directions: northeast, northwest, and north-south; and (7) comparison between image numbers ERTS E 1049-17324-7 and ERTS E 1067-17324-7 is that the latter imagery, acquired 18 days later, has higher contrast especially in regards to tracing faults that occur in alluvial fans.
