WELCOME!
This blog offers an exceptional discovery analizis the layers of our planet from the Earth's crust to the depths of hot mantle into the secret core of the planet. Also offers a look at what man kind will probably never reach, the more alien and hostile to the rocks, lava, and minerals below the earth's crust. While the crust is approximately 20 to 30 km deep in most places, humans have never traveled further, even so, research continues to prove impossible.We can say that the interior of the Earth has many aspects that makes it a unique theme.Hopefully you people like this. Thanks!
Composition, melt structure and properties.
Silicate melts are composed mainly of silicon, oxygen, aluminium, alkalis (sodium, potassium, calcium), magnesium and iron. Silicon atoms are in tetrahedral coordination with oxygen, as in almost all silicate minerals, but in melts atomic order is preserved only over short distances. The physical behaviours of melts depend upon their atomic structures as well as upon temperature and pressure and composition.
Viscosity is a key melt property in understanding the behaviour of magmas. More silica-rich melts are typically more polymerized, with more linkage of silica tetrahedra, and so are more viscous. Dissolution of water drastically reduces melt viscosity. Higher-temperature melts are less viscous.
Although now covered by forest the mountains around Panguipulli Lake in Chile were once magma that crystallized deep in earth's crust, now these magmatic bodies form the Panguipulli Batholith.
very excelent information this theme is very important excelen work!!
