Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

Formation
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

All about Latite and Migmatite Properties
Know all about Latite and Migmatite properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Migmatite belongs to Metamorphic Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Migmatite is Foliated. Latite appears Rough and Migmatite appears Dull, Banded and Foilated. The luster of Latite is subvitreous to dull while that of Migmatite is dull to pearly to subvitreous. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. The commercial uses of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo) and that of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends.
