1 Definition
1.1 Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism

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.
Slate is a low grade metamorphic rock that is generally formed by metamorphosis of mudstone or shale, under relatively low pressure and temperature conditions.

All about Latite and Slate Properties

Know all about Latite and Slate properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Slate belongs to Metamorphic Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Slate is Foliated. Latite appears Rough and Slate appears Dull. The luster of Latite is subvitreous to dull while that of Slate is dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Slate is available in black, brown, buff, green, light to dark grey, purple, red, shades of blue 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 Slate are blackboards, commemorative tablets, laboratory bench tops, standard material for the bed of billiard table, standard material for the beds of pool and snooker table, tombstones, used in aquariums, writing slates.
