What do you make of APS mineral systems. I expect Cl bearing zunyite for instance. Where do you think the K comes from in the fertile potassic zone of many porphyry coppers. Isotope studies invoke a magmatic origin for oxygen but I am suspicious about the source of K…even in magmatic systems. Amphiboles? I keep thinking phyllosilicates…but then in mantle rock…nah. From crustal contaminants?

Very good. I have been playing about with a theory regarding UMV deposits where I live in Galena IL. "Did the zinc come with oil?" It is my belief that the rotten dolomite we have here is due to oil penetration and its subsequent self oxidation and generation of heat, not unlike a burning coal bed. I know the story of migration updip by basin brines etc. but I do feel the escape of petroleum and the metals associated with such mixtures of water, salt, oil and metals might deserve sticking ones neck out a bit and asserting that most of the metals were carried with the oil. I claim that there is a reasonably good working hypothesis using automotive oil and its use of zinc phosphates in the presence of sulfur bearing oil, etc. The black sludge in engine oil supposedly hosts a surprising amount of sphalerite that plugs oil circulation holes over time. I am also struck by the vast amount of fluorescent hydrozincite and smithsonite that leak out of irregularly ameboid pockety yellowed rock over large areas here in the UMV. I assert that most of the yellowed argyllic dolomitic rock was soaked in residual metals after the fluids "cooked off" including the problematic lead and low level uranium that provides the radon we all know and love. Some places show yellowed and non yellowed dolomite in the same block. Cute really. There are plenty of structural features hosting sulfides that were mined but I am struck by the hydrozincite that positively leaks out of the rotten rock. I put together a little on Linked-in to that effect, mostly because I seem to have a house that is notched into vuggy if not cavernous porosity of the Galena Group and which produces blocks ranging up to 40-50 lbs of late karstic zinc carbonate passageway plugs, breccias and speleothem features that I stumble over, especially where my neighbors are doing new builds. I have seen your website...it's very good! Myself....I just JV'd a porphyry Cu in Chile and accidently bought into the UMV zinc mineral geology that runs in cavernous material under not only my house but for 75 acres or more hereabouts. My little UA-cam channel shows a bit. My researchgate work regarding anhydrite in porphyry systems is more interesting. I claim the anyhdrite is essential to formation of a metallic cu sulfide body by fixing what was much more mobile as a Cu oxide. Check it out. So....what next dolomitization as an essential step in fixing mobile Pb/Zn oxide minerals like in Ca extraction from feldspars and hydrolysis to form porphyry systems?
