Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its …

Porphyry (geology) - Wikipedia

The term porphyry is also used for a mineral deposit called a "copper porphyry". The different stages of cooling that create porphyritic textures in intrusive and hypabyssal porphyritic rocks also lead to a separation of dissolved metals into distinct zones.. This process, which occurs primarily when fluids are driven off the cooling magma, is one of the main reasons for the existence in the ...

Preliminary Model of Porphyry Copper Deposits

Porphyry copper deposits result from the complex interactions and feedbacks of many processes.

Hydrothermal alteration of the rocks of the Morenci porphyry copper deposit is well described in Lindgren (1905a), Reber (1916), Bennett (1974), Preece, Stegen and Weiskopf (1993), and Walker (1995). Descriptions of the Tertiary volcanic and sedimentary rocks are primarily derived from recent mapping by Ferguson and Enders (this report).
