Geologists split Arizona into three provinces: Ranges are followed by basins and the sites is repeated over and over and over — it’s like paying taxes gold it just never seems to end.
The province is a result of a major head-on collision by tectonic plates that buckled the western US. In fact, geological evidence suggests the Pacific plate on the west collided with the North American plate resulting in fractures that propagated through the lower crust and providing conduits for volcanic eruptions throughout much of the province. Many mountain ranges popped up in between all of the basins. Everywhere one looks, they see evidence of past volcanic eruptions dating from the Tertiary to Sites time.
Basalts, rhyolites, flows, plugs, dikes, ash falls, etc. Some even look like they erupted just last weekend. Further north, the Colorado Plateau represents a geologically stable province.
While the Basin and Range suffered considerable folding, quartsite and vulcanism; the Colorado Plateau had only minor deformation over the past million years. Gold deposits are often found where considerable fracturing, deformation, sites occurred.
Thus areas of greatest potential for gold in Arizona are within the Basin and Range and Transition zone provinces Hausel, But, Arizonians suffer with hot summers and deserts that lack water needed for sites mining and lode mills, but it is still a wonderland for prospectors.
If the heat isn’t bad enough, there is the added concern of foreign drug runners, terrorists with automatic weapons entering the US along the Mexican border, and snowflakes from California. This is emphasized by a memorial to police officers killed by mining immigrants.
Phoenix became a kidnapping capital with activity related to illegal immigrants, Mexican cartels, and human smugglers. Only Mexico City had a higher kidnapping rate. It has been closed to US citizens since even though it has considerable mineral potential. Much of which is mined from giant porphyry copper deposits where gold and silver is recovered as by-product of primary copper, zinc, lead, etc. This texture is a rock fabric in which large crystals such as feldspar and quartz are dispersed throughout a finer grained matrix in an igneous rock as a result of slow cooling in a magma chamber at relatively shallow depth.
These veins provide excellent targets for gold and silver. In addition, exploration continued at Resolution, Rosemont and elsewhere Niemuth, Total historical gold production from Arizona is about 16 sites ounces since records were kept beginning in the late 19th century. The state could produce considerably more by providing exploration and mining incentives sites by providing free prospecting education to the public Hausel, ab.
Primary gold lodes include the Vulture mine, which producedounces of gold in the Wickenburg district north of Phoenix, the Oatman and Katherine camps which produced more than 2 million ounces of gold in the San Francisco district NW Arizona Koschman and Bergendahl, Gold is found at Lost Basin and Chloride in western Arizona.
Gold is described in several districts by Wilson and others and Wilson Gold Placers Gold placers occur in many counties in Arizona. Similar to Australia, active stream placers are rare because of the lack of perennial streams.
