Significance of Plutons, Question regarding Plutons Options

[Shawnee Man]

I read the thread on the significance of faults. It brought to mind another geology question. I have been doing some reading on the Pikes Peak Batholith and found that the formations of Plutons in this area seem to have a correlation with mineral formation. Can someone expand on this for me please?

I imagine a geologist could wax poetic about this, but my understanding is a lot of the minerals were injected into the veins and fractures around plutons via a hydraulic process (minerals are dissolved into a solution, heated and the gases/liquids condense in the veins).

This may help (excerpt taken from page 45 Epithermal Gold Deposits Part II):

A process of mixing of magmatic solutions with a peripheral convective meteoric water system in the vicinity of a differentiating pluton is consistent with the timing, zoning, and characteristics of the numerous deposit types near the Porphyry Mountain stock. Gold deposits elsewhere in the district may have had a similar origin, although a relationship between intrusive events and vein deposition elsewhere is less clear.
