5.1 Formation

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Migmatite and Laterite Properties

Know all about Migmatite and Laterite properties here. All properties of rocks are important as they define the type of rock and its application. Migmatite belongs to Metamorphic Rocks while Laterite belongs to Sedimentary Rocks.Texture of Migmatite is Foliated whereas that of Laterite is Earthy, Massive, Porphyritic. Migmatite appears Dull, Banded and Foilated and Laterite appears Rough and Banded. The luster of Migmatite is dull to pearly to subvitreous while that of Laterite is dull. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors whereas Laterite is available in brown, buff, red colors. The commercial uses of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends and that of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
