Formation
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.
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.

All about Marl and Latite Properties
Know all about Marl and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Marl belongs to Sedimentary Rocks while Latite belongs to Igneous Rocks.Texture of Marl is Earthy whereas that of Latite is Aphanitic to Porphyritic. Marl appears Rough and Dull and Latite appears Rough. The luster of Marl is dull while that of Latite is subvitreous to dull. Marl is available in beige, brown, green, grey, white colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Marl are creating artwork, soil conditioner and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
