Temperature To Melt Granite

Granite has poor primary permeability overall but strong secondary permeability through cracks and fractures if they are present.

Temperature to melt granite.

The melting point of granite is 550 degrees c. Melting points of rocks igneous rocks form through the crystallization of magma there is a considerable range of melting temperatures for different compositions of magma. Because of the mineralizers in the magma the temperature interval over which it crystallizes will be lower than that over which the rock can be melted in an open crucible in the laboratory. The presence of water in the rock is important to lower the melting temperature.

Please check the following site for more information. Strictly speaking geo thermal necessarily refers to earth but the concept may be applied to other planets. Please note the fact that melting point of granite is 2210o to 2300o f 1210o to 1260o celsius whereas you cook your steak at around 350o to 450of 177o to 232o celsius. Often the silicates are grouped as high medium and low melting point solids.

It is strongly reduced in the presence of water down to 650 c at a few kbar pressure. Geothermal gradient is the rate of increasing temperature with respect to increasing depth in earth s interior. If you were trying to melt hawaiian basalt lava it would not melt but it would glow bright orange. If you were trying to melt granite or a mixed sediment not pure quartz or calcite which occurs on some beaches it would almost certainly melt.

This video is aheating melting and vitrification of granite by the halogen point heater. Away from tectonic plate boundaries it is about 25 30 c km 72 87 f mi of depth near the surface in most of the world. You may feel further comfort about granite s heat resistant properties when you know that steel starts melting at 2498o f 1370o c. All the silicates are molten at about 1200 c when a part of rock and all are solid when cooled to about 600 c.
