The Occurrence of Uranium in the Diamond Head Group, Sierrita Mountains, Pima County, Arizona

Description: Abstract: The Diamond Head droup area is entirely igneous. Tight fractures in alaskite and granite, which have been altered by heiratite and kaolinization contain narrow seams and very locally,pods of sooty uraninite. A greater percentage of the structures in the area strike about east-west and dip steeply to the north, while the radioactive structures have similar strike, they dip steeply to both the north and the south. A drift has been driven on a mineralized structure far enough to ascertain that the general character of the mineralization is very narrow seams. Many such seams exists but are scattered throughout the area.
