copper porphyrycopperandesandesitesubduction zonearc volcanismMuch of the world's economic copper resources are hosted in porphyry copper deposits (PCDs), shallow level magmatic intrusions associated mostly with thick (>45km) magmatic arcs, such as mature island arcs and continental arcs. However, a...
Some copper deposits provide an example of this. By far the largest amounts of copper are found in the crust in bodies known asporphyry copper deposits. Copper is often associated with other metals such as lead, zinc, gold, and silver. These deposits were once large masses of molten rock ...
We have seen that reserve-to-production ratios (R/P-ratios) are useless to predict the lifetime of raw material reserves. They are more influenced by ore deposit type than possible lifetime. For instance, commodities that occur mainly in lenticular deposits like the base metals copper, lead a...
However, it is important to recognize that in all cases, whatever the triggering mechanism (Fig.1), the forces that ultimately drive the liquefaction and the flow failure of liquefied material are permanent or gravitational. In this sense, the types of liquefaction "dynamic" or "static" do not...
