Geologic map of the Patagonia Mountains, Santa Cruz County, Arizona
Spatial databases for map units, strike and dip, geologic contacts, faults, dikes, in addition to a topographic base map are provided in an Esri file geodatabase. The geologic mapsheet is also provided as a PDF. |

Geochemistry of soils from the San Rafael Valley, Santa Cruz County, Arizona
Surficial geochemical methods used to identify subsurface mineral deposits covered by alluvium. Can a geophysical anomaly, interpreted as a buried granite pluton, be discerned from the geochemical characteristics of overlying Quaternary sediments? |

An interpretation of the 1996 aeromagnetic data for the Santa Cruz basin, Tumacacori Mountains, Santa Rita Mountains, and Patagonia Mountains, South-Central Arizona
Measurements of in-situ magnetic properties of several map units to determined whether or not mapped lithologies were responsible for aeromagnetic anomalies observed in a previous high-resolution survey (data of Sweeney, 2000). |

Geochemical and mineralogical study of the Red Mountain porphyry copper-molybdenum deposit and vicinity, Santa Cruz County, Arizona
Extensive core drilling has delineated a large, deep seated, structurally intact deposit here. Distribution of elements and minerals determined for this study provide a zoning model applicable to similar deposits and useful for resource exploration. |
