[quote:Esoteric Morgan:MV8yNTIyMjQyXzQ0MTA3ODM1X0E0ODBEQ0Iz] [quote:Shadow Beam:MV8yNTIyMjQyXzQ0MTA3NjMyXzMwN0E2NDFB] Hey iv got a theory on the grey/milky/ash like substance that was seen around the geyser sites...... What if it was a layer of quartz being pushed up due to a swell in magma volume? It makes sense large deposits would form beneath the geyser basin. And would be pushed and ouzed out if a swell pushed from below [/quote] I know what you mean. I wrote about it earlier today http://www.godlikeproductions.com/forum1/message2522242/pg107#44099340 but will copy it here, just in case you missed it: ______________________________________________ I do see two trees which appear to be tilted, yet, they look exactly the same in the older shot...although the ground definitely has that white coating on it now, which was not evident then. [b]This is the same 'white' stuff I now see on the hill.[/b] If you caught a post I made some days ago, I commented that I saw a mass of thick whitish stuff spew out from the mound to the NE of Old Faithful. I think that around those steamy days a week or so ago, excessive water may have eroded into it excessive volumes of minerals, or simply picked them up, which have been coming out with the steam now and then ever since, falling where they may from the steam they are traveling on. I also suspect that this is the cause of the fine particles we have seen at least twice on most of the camera lens covers. I did do a search, trying to determine what it might be, I did see that magnesium, barium. silica are among the minerals which are deposited during geyser emissions...and, I further tried to find out if these travel on magma -and might be considered a lava precursor, or lava-like or even a FORM OF MAGMA, which could then be an indication that things are ramping up. Well, so far, I have NOT found ANY paper which allows[i][b] that lava can have such thin viscosity[/b][/i] as to be considered lava at all, even if mixed into and emitted along with volumes of steam and water. Ha! My mind tells me to keep looking, because I HAVE read this about rhyolite lava: "Rhyolite is a felsic extrusive rock. Due to the high silica content, rhyolite lava is very viscous. It flows slowly, like tooth paste squeezed out of a tube, and tends to pile up and form lava domes. If rhyolite magma is gas rich it can erupt explosively, forming a frothy solidified magma called pumice (a very lightweight, light-coloured, vesicular form of rhyolite) along with ash deposits, and / or ignimbrite. In certain situations extremely porous rhyolite lava flows may develop. The extreme porosity of such flows allows degassing and subsequent collapse of the flow, forming obsidian (dark coloured volcanic glass)." http://flexiblelearning.auckland.ac.nz/rocks_minerals/rocks/rhyolite.html I have also read this: Viscosity of Magmas Viscosity is the resistance to flow (opposite of fluidity). Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO2 (silica) content magmas have higher viscosity than lower SiO2 content magmas (viscosity increases with increasing SiO2 concentration in the magma). Lower temperature magmas have higher viscosity than higher temperature magmas [b](viscosity decreases with increasing temperature of the magma)[/b]. [Meaning: 'is thinner'.] Thus, basaltic magmas tend to be fairly fluid (low viscosity), but their viscosity is still 10,000 to 100,0000 times more viscous than water. Rhyolitic magmas tend to have even higher viscosity, ranging between 1 million and 100 million times more viscous than water. (Note that solids, even though they appear solid have a viscosity, but it's very high, measured as trillions times the viscosity of water). Viscosity is an important property in determining the eruptive behavior of magmas... ...In general more siliceous magmas form by low degrees of partial melting. As the degree of partial melting increases, less siliceous compositions can be generated. So, melting a mafic source thus yields a felsic or [color=red][b]intermediate magma[/b][/color]. Melting of ultramafic (peridotite source) yields a basaltic magma. Magmatic Differentiation But, processes that operate during transportation toward the surface or during storage in the crust can alter the chemical composition of the magma. These processes are referred to as magmatic differentiation and include assimilation, mixing, and fractional crystallization... ...Assimilation - As magma passes through cooler rock on its way to the surface it may partially melt the surrounding rock and incorporate this melt into the magma. Because small amounts of partial melting result in siliceous liquid compositions, addition of this melt to the magma will make it more siliceous... ...If the liquid part of the magma has a low viscosity, then the gas can expand relatively easily. When the magma reaches the Earth's surface, the gas bubble will simply burst, the gas will easily expand to atmospheric pressure, and a non-explosive eruption will occur, [color=red][b]usually as[/b][/color] a lava flow (Lava is the name we give to a magma when it on the surface of the Earth)..." http://www.tulane.edu/~sanelson/Natural_Disasters/volcan&magma.htm My query is: what if we are talking SMALL VOLUMES at the outset? What if we are seeing exposures of extremely low viscosity liquids -a.k.a. [i]a pre-lava[/i]- which are being finally carried upwards to the surface after settling on the surface of rock not yet melted for 70, 000 to 630,000 years? Think of it this way: Yellowstone is a cacophony of all sorts of deposits, some which are slowly creating fumeroles and domes and mounds...which are ALL considered to be part of the process of HOW VOLCANOES FORM. Put another way: we know that [i]every day[/i], geysers and pools at Yellowstone continue the process of volcanism, as seen in the deposits they issue forth. WHY NOT A 'PRE-LAVA' lava stage? The stuff that has been sitting underground all these millennium is being stirred up, mixing in with passing waters, has to come out at some point. The very fact that Yellowstone has been SO QUIET as a Supervolcano does NOT discount the fact that volcanic processes are occurring every day within the park. [i](Whew! I need to breathe a second or two.)[/i] Therefore, I will continue my quest to find out if any professional through the ages has also considered that there might be a noticeable [color=red][b][i]pre-eruptive effusive-eruptive stage[/i][/b][/color] to be seen in effusions at volcanic sites. Why can't lava be sooooo very less vicious in it's early stages, as its main volume of magma creeps to the surface? [i]Is [b]THAT[/b] part of what we are seeing in the park[/i], as seen in powder on lenses, and now 'covering' a good deal of the landscape -as light as it might be, and what's trailing down the mound ever so little near LION, and what spewed forth from that dome some days ago, as I've already noted? There must come a point where we think carefully about subtle things right before our very eyes. ____________________________ Good to know I am not alone in my considerations. Maybe there is something to it. :cool2: [/quote]
