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.
Marl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock.

All about Latite and Marl Properties
Know all about Latite and Marl properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Marl belongs to Sedimentary Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Marl is Earthy. Latite appears Rough and Marl appears Rough and Dull. The luster of Latite is subvitreous to dull while that of Marl is dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Marl is available in beige, brown, green, 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 Marl are creating artwork, soil conditioner.
