What is solidus and liquidus temperature of granite?

My understanding is that because a rock is composed of variety of minerals, so it does not have fix melting point, rather there is a range below which whole rock is solid and above which whole...

Which equations describe complete (or near complete) behaviour of magma moving through rocks?

Yes this is a bit broader question but I want to know which processes play their role in movement of magma. If one wants to model magma intrusion in rocks, which processes should one not miss at...

Comparing use of Laplace equation with diffusion equation to simulate flow of fluid/water through porous media?

What is the difference in using Laplace equation (say only in 1D) to simulate water flow in a porous media (aquifer) with that of using diffusion equation for same purpose?

Which numerical integration method is best for a function which behaves like a flood wave?

I want to estimate a function for flood wave which means the function first rises suddenly (in relative term) and drops slowly. I mean, it is not a perfect sine wave. It has been solved by...
