dc.descriptionThis report provides average grades for all metallic mineral districts of Arizona. Metallic mineral districts were defined by Keith and others (1983a,b) as a means to classify mineral occurrences by virtue of their geologic and metallogenic characteristics, rather than the geographic parameters used in a traditional mining-district classification. The mineral districts are not intended to circumvent traditional mining districts, but rather to provide a more scientific and rational means of studying mineral occurrences and to determine the geologic interrelationships among mines, prospects, and discoveries.
