1.1 Definition

Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture

5 Formation

5.1 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.

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

All about Latite and Tonalite Properties

Know all about Latite and Tonalite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Tonalite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Tonalite is Phaneritic. Latite appears Rough and Tonalite appears Banded and Foilated. The luster of Latite and Tonalite is subvitreous to dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Tonalite is available in black, brown, light to dark grey, white 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 Tonalite are cemetery markers, creating artwork.
