Bigger and Bigger and Bigger Copper Deposits|
January 26, 2014 | Arizona Geological Survey on YouTube
Although one would expect the largest mineral deposits to be the first ones exploited, the opposite has been true for copper deposits in Arizona. The large deposits have a grade of ore that can more effectively be processed with new technologies.
In this video, Spencer Titley, a pioneer in the understanding of porphyry copper deposits, explains how some of the earliest geologic mapping done by USGS geologists in Arizona is still being used.

Hear Earthquakes Triggered by the Bingham Canyon Mine Landslide|
January 7, 2014 | The University of Utah
“Last year’s gigantic landslide at a Utah copper mine probably was the biggest nonvolcanic slide in North America’s modern history, and included two rock avalanches that happened 90 minutes apart and surprisingly triggered 16 small earthquakes.” Quoted from The University of Utah press release.
The story is accompanied by a sound file that allows you to hear the second rock avalanche followed by three earthquakes.
Impact of Arizona Geology on Geologic Concepts|
January 1, 2014 | Arizona Geology
“Arizona makes up a tiny fraction of the land surface on Earth. However, it has had a comparatively larger impact on the evolution of geologic concepts, especially in three areas of geologic inquiry: (1) porphyry copper deposits, (2) metamorphic core complexes, and (3) evolution of large rivers.” Quoted from the Arizona Geology article.
