Why Earth's mantle is solid

The amount of granitic crust which could exsolve is pretty high, if the mean composition is that of albite perhaps 20% of the mantle in the extreme - but this would not be reached until far below the solidus. Actually, I found out that Earth is very depleted in alkalis, so the mantle Al/alkali ratio is more like 8 than the cosmic ratio of 1.3 . The composition of granitic rocks would remain practically constant across this range with an effective ratio (after including Ca and other cations) of 1, so merely the amount of granite wolud change. It is not likely that any celestial body could go the other way, with an enrichment of alkalis compared to Al, so the main composition of granitic rock (alkali aluminosilicate) should be the same everywhere, though the lesser elements will vary.

I am working with rotational dynamics privately and watching plate tectonics become diluted through stationary Earth convection cells notions,basically a cartoon mechanism applied to a genuine insight and that is as far as I go. I watched what Newton did to heliocentric reasoning in creating a conclusion that the planets behave like objects on Earth (terrestrial ballistics) and then twisted everything towards bridging that link much like what happens with ee or convection cell conclusions.Some of the greatest known Western insights,specifically the resolution of retrogrades via the Earth's orbital motion,was vandalised to bump up his 'forces' agenda at the expense of brilliant reasoning by people like Copernicus,Kepler and Galileo.

How do they really know what the mantle is made of? The crust is differentiated from the mantle, oceanic crust less so than continental. We know the composition of the mantle, I think, largely from astronomical abundances. So are you saying that the mantle more closely resembles the materials in outer space? If so, then why is that the case when the crust is much more closer to outer space than the mantle? There was a story some time ago which states that some parts of the ocean are just exposed mantle areas. Mission to Study Earth's Gaping 'Open Wound' | LiveScience http://www.livescience.com/environme...ed_mantle.html Anyways, what's the liquid (i.e. magma) that exists below the crust made of? Is it liquefied crust, or liquefied mantle? If it's liquefied crust, then isn't that another example of a liquid existing below its solid phase? Magma is formed by partial melting of either mantle or crust. Yes, it is less dense than surrounding rock, which is why it moves upward. You could probably the same thing about water and ice. As the ice cracks and melts, water upwells into it from below. Yousuf Khan |

Mission to Study Earth's Gaping 'Open Wound' | LiveScience http://www.livescience.com/environme...ed_mantle.html Below an ocean depth of 3 km crust (basalt) formation declines. It is replaced by formation of mantle (dunite) composed primarily of olivine (peridot). Below 3 km of ocean pressure silicon becomes more soluble in water. It combines with four molecules of water to form silicate anion which on contact with iron or magnesium precipitates as olivine, Fe2SiO4, Mg2SiO4. Between 2-3 km of water silicon is less soluble and combines with only 3 molecules of water to form pyroxene FeSiO3 and MgSiO3 which are the primary ingredients of basalt. Somewhere between 1-2 km of ocean depth silicon no longer dissolves in water. It bubbles to the surface where it reacts with atmospheric oxygen to form SiO2 , the primary component of ash and pumice rafts: http://earthobservatory.nasa.gov/New...3?img_id=17461 John Curtis |

Every solid save water ice and a few semi-metals is denser than the liquid of the same composition, and the same temperature and pressure. This means that a liquid other than water will not exist beneath a solid of the same composition in a planet. A magma ocean therefore can only freeze from the bottom up, except for the granitic crust which, owing to its composition, is lighter than the liquid mantle. The amount of granitic crust which could exsolve is pretty high, if the mean composition is that of albite perhaps 20% of the mantle in the extreme - but this would not be reached until far below the solidus. Freezing from the bottom up is a much faster process than freezing from the top down, as the heat flux from below continues to decrease (yes, there is convection, but the effective viscosity is much higher in a solid than a liquid), and therefore should go to completion. Andrew Usher The crust of our Selene/moon is much thicker and more solid/robust than anything Earth has to offer. Our gamma saturated Selene/moon also has a greater surface than core density, plus having been bleeding off or leaching sodium like there’s no end in sight. The crust of Venus most likely isn't half the thickness of Earth's, and Mars is nearly frozen or solidified solid to the core. What's not adding up? I tend to favor that intelligent ETs would find our relatively passive and extensively IR producing sun as that offering a DNA/RNA friendly sort of solar system, especially while visiting or pillaging magnetosphere protected planets, possibly including a few of those impressive Jupiter or Saturn moons, and not by any means to exclude the geothermally active plus mineral and natural energy rich worlds having thick/robust atmospheres like Venus, of which most folks like yourself are either mainstream petrified as dumbfounded past the point of no return, and/or having been mainstream status quo scared spitless if not to death of Venus. btw, any kind of historical revision pertaining to mainstream science is simply not permitted by those in charge. It’s a mutual cover thy butt kind of inside policy, with more faith-based strings attached than even you can imagine. If Hitler were still alive, he’d have one of those big ass smiles on his face, highly appreciating as to what his Zionist/Nazis had accomplished. ~ Brad Guth Brad_Guth Brad.Guth BradGuth BG |
