The california poppy (eschscholtzia mexicana) as a copper indicator plant - a new example
The abundance and distribution of the California poppy (Eschscholtzia mexicana) correlates closely with the copper-rich outcrop of a small porphyry-type deposit in Arizona. Chemical factors are probably more important than physical factors in determining why this species is sometimes found as a copper indicator plant. ?? 1976.

The zonal distribution of selected elements above the Kalamazoo porphyry copper deposit, San Manuel district, Pinal County, Arizona
There may be many as-yet-undiscovered porphyry copper deposits that exist as blind deposits deep within exposed rock bodies. The Kalamazoo porphyry copper-molybdenum deposit is a blind deposit present at depths up to at least 1,000 m (about 3,200 ft) that contains zoning features common to many of the known porphyry copper deposits found in western North and South America. As the preliminary phase

Geochemical Exploration Techniques Applicable in the Search for Copper Deposits
Geochemical exploration is an important part of copper-resource evaluation. A large number of geochemical exploration techniques, both proved and untried, are available to the geochemist to use in the search for new copper deposits.
Analyses of whole-rock samples have been used in both regional and local geochemical exploration surveys in the search for copper. Analyses of mineral separates, su

Stratigraphic relations of the Bolsa Quartzite, Vekol Mountains, Pinal County, Arizona
A quartzite unit occurring between the rocks of the Precambrian Apache Group and those of the Cambrian Abrigo Formation in the Vekol Mountains, Final County, Ariz., has been called both Troy Quartzite (Precambrian) and Bolsa(?) Quartzite (Cambrian). Regional and local geologic relationships indicate that this intervening unit is definitely the Bolsa Quartzite. The Bolsa ranges in thickness from at
