Definition
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles

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.
Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.

All about Latite and Shale Properties
Know all about Latite and Shale properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Shale belongs to Sedimentary Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Shale is Clastic, Splintery. Latite appears Rough and Shale appears Muddy. The luster of Latite is subvitreous to dull while that of Shale is dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Shale is available in black, brown, buff, green, grey, red, yellow 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 Shale are creating artwork, pottery.
