<<All one needs is some mantle derived rocks, a conductive heat cell, and a good degree of immiscibility with respect to Pt and Pd. Given the heat and pressure of below - Moho rocks, what sort of volatile phase would exist? >> I agree, I have been reading some of the "Geology & Mineral Resources of Arizona" Bulletin 180 ( part 1) rev 1991 by the AZ Bureau of Mines. In Figure 73, on pagee 455, there is an AZ map, on Celestite Deposites, one is at the mid point of the location of IPM-GPGI-MXAM and says; "in the Southwestern United States, bedded deposites of Celestite that intermittently have been exploited are found intercalated with tuffaceous lake sediments. It has been suggested that the strontium was introduced into the lake s by volcanic emanations from adjacent areas.(Harness , 1949, p.980) ...Az Deposites , Two deposites ...the largewr Vulture Mountains in No Maricota County, ...buff to lite brown shaly tuff of Tertiary Age. ...Celetite Rock about 160 Ft thick...and ...and the (so this is near Desert Dirt USPS) smaller of the two deposits is about 15 miles south of Gila Bend ... Celestite occures with beds of gypsum, sandstane and conglomerate in a zone 40 -50 feet thick and a mile long. Igneous flows and intrusions also are associated with the series....if extends along strike..which seems probable...is much greater. Thia all is in a section titled Strontium Salts...Alkaline Earth group...ie calicum...SG of 2.6 melting pt at 1,395* F. ...few uses...vivid red flame.
...are commonly flanked by sediments of the early Cenozoic Age , of fine grain volcanic debris,...siltstone...silty limestone...of lagoonal origin. ...sediments are the most favorable rocks for the occurrence of Celestite.""
Thus, in my Geo 101 study I see a relationship between 5 Desert Dirts actual location on this map and 2 volcanic emantations and I believ one cone is callled Coyota Peak over at IPM, so we have a Volcanic Sourse bringing up Moulton Matter up from the mantle and hitting a home run and rounding the bases with a future age in our old past as a lagon in a lake ( ie Franklin Lake Sceranio) and thus a reason for PGMs and specufically; Platinum and Palladium to actually exist in Arizona. I bot this book 30 feet away from The Desert Foxs' ( Mason Jar Coggins') actual office at the AZBOM on 22 June 1997. The forward has several pages in the platinum section telling miners why there is not any economic Platinum in Arizona -I expect tp scan that whole section onto the IPM, GPGI, USPS, MXAM threads within 28 days!
Chuca-I rest my case, it is a self taught opinion, I failed Geology. But I might win the GAME!
