Description:
This study concerns the distribution, geologic character, probable
extent, and potential economic importance of those various mineral
substances that have been found to occur within the Gila River Indian
Reservation in Arizona. Information regarding these items was obtained
by means of geologic examination and mapping, supplemented by laboratory
tests and analyses, during a period which extended from April
17 to August 18, 1963.
The report offers suggestions for future prospecting and field exploration,
but it does not attempt to give quantitative (tonnage) estimates of
the occurrences of economic materials or the total value for any of the
mineral deposits.
