A study of the Ajo copper ore mineralsStewart, Lincoln A., Stewart, Lincoln A. January 1933 (has links)
The following thesis describes part of a set of ore
specimens collected by James Gilluly and the writer at Ajo,
Arizona during the early summer of 1932. This field work
was done for the United States Geological Survey, and
while considerable geologic work was done, only passing
mention will be made concerning the geology, as the
conclusions reached properly belong to Mr. Gilluly and
will be published by him at some future time. Mr Eldred
Wilson of the Arizona Bureau of Mines has kindly put at my
disposal a number of polished sections which he collected
in 1923 from the semi-oxidized zone in the southwest part
of the orebody. In all, about 50 polished sections were
studied in detail and the conclusions reached concerning
the paragenesis of the ore minerals are based entirely
upon the evidence presented by these sections, as the
field relations are not in my possession.
