WebHow does magma behave? When melting first occurs, it happens at the peripheries of individual crystal grains (b - right), yielding minute pockets of magma. When these pockets grow to the point that they interconnect (a - right) the magma is able to move. Being liquid, magma tends to be lighter than surrounding material from which it has melted. Web1 day ago · Granitoids, as a major component of the Earth's crust, have large K isotopic variations (δ 41 K = −1.0‰ to 0.4‰), but K isotope fractionation during granite differentiation is poorly constrained.
