Bubbling Magma Chambers, Cupolas, and Porphyry Copper Deposits
2010年7月6日 Porphyry copper deposits of common size can form during the solidification of large stocks. Super-giant porphyry copper deposits can form where the saturation front propagates from a stock into an underlying batholithic chamber with a magma volume on the order of 1000 km 3 and a top at depths of 10 to 15 km.

Temporal and Spatial Relations Between Porphyry Copper Deposits
2024年9月1日 Laramide porphyry copper deposits are commonly located within the footwalls of major reverse fault systems. Given the typical postshortening timing of deposits in this province, the footwall location suggests that topography generated from major uplifts aided preservation of ore deposits in the footwalls of basement-cored uplifts.
MoreThe Chain of Processes Forming Porphyry Copper Deposits—An
2024年6月1日 Entrainment of any suspended sulfide particles is favored by forceful ascent of magmas in the tectonic setting where porphyry copper deposits are found (Loucks, 2021), and the H 2 O-rich and oxidized composition of such fertile magmas promotes subsequent sulfide decomposition and transfer of sulfur and metals to ore-forming fluid in the upper ...
