You babble shit. I have an FTIR laser lab and I am 20 years ahead of your technology on how it works. In your lifetime you cannot catch up. I specifically study supercritical fluid transitional silica species to understand geologic systems better, well for you, to start studying them competently. Beta-moganite. Top of the vapor-pressure transitional curve to supercritical. Brazil twinning. Sits under supercritical transition. When you get your head out of your ass, tho maybe never, you will come to understand that every “water” fluid state transition defines a new silica mineral species. At beta-quartz is the transition from supercritical to ultra-supercritical. I did not make that up. That comes from chemical engineering when you learn to read. The top end of ultra-supercritical is the transition to rhyloite lava and is where amphiboles live, meaning silica itself does not exist, it forms silicates (metal silica oxides). All of the lavas, their states and behaviors, is defined by the fluid system they interact with. So, how do you make rhyolite from basalt? The formula is, basalt + USCW = rhyolite. Basalt sits above ultra-supercritical. Yeah, I know, this is geochemistry a thousand years beyond what GIA is going to comprehend. Did you know you can find all beta-silica mineral species in infrared? Oh yes you can. Now, it only take a couple degree bond angle shift on cooling for beta-quartz to go to alpha, so smarte Don, how do you claim you can find beta-quartz, and it is still around? This was the question put to me from Caltech. No problem. Alpha-beta transition does not exist. It is actually alpha, incommensurate, then beta. So, I don’t see beta-, that is slang to talk to you. I see incommensurate. Shit that is 1.5C under beta, which you cannot measure, but I can see incommensurate in infrared, and functionally there is no difference for you from beta. Well, one difference. Incommensurate is stable upon cooling. Whoa, there you go. Disprove incommensurate is not metastable. You cannot. I have a statistical regression of 0.998 where 1 is a perfect correlation where incommensurate/beta sits right on that trend where it is supposed to live. Deal with it. Statistics. 0.998 regression is not coincidence. It is called a law of physics. You learn about ulta-supercritical in coal power generation chemical engineering. It is the next state of ‘water” where it dehydrogenates, the hydrogen kicks off and the “OH “water” becomes a super oxidizer. Then the hydrogen reacts with carbon in carbon-steel of heat exchangers of power plants. That makes methane which blisters the steel and embrittles it to fail. That is why ultra-supercritical is so important to power plant engineers. To bad and so sad general geology is not competent enough to use that tech and get with the program of how volcanology really works. Oh, and can I tell free water from OH hydroxyl “water” from mineral surface water, from caged (in crystal structure) water? Oh yes I can. They all behave differently in infrared. Minerals have 4 kinds of “water”.
