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.

Marl vs Latite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Marl and Latite Reserves. Marl is an unconsolidated sedimentary rock consisting of clay and lime. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Marl vs Latite information and Marl vs Latite characteristics in the upcoming sections.

More about Marl and Latite

Here you can know more about Marl and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marl and Latite consists of mineral content and compound content. The mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Marl vs Latite, the texture, color and appearance plays an important role in determining the type of rock. Marl is available in beige, brown, green, grey, white colors whereas, Latite is available in black, brown, green, grey, pink, white colors. Appearance of Marl is Rough and Dull and that of Latite is Rough. Properties of rock is another aspect for Marl vs Latite. The hardness of Marl is 2-3 and that of Latite is 5-5.5. The types of Marl are Clay Marl ,Blue Marl, Red Marl, High Bank Marl, Shell Layer Marl, Under Shell Layer Marl, Sand Marl, Green Marl, Grey Marl and Clayey Marl whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marl and Latite is white. The specific heat capacity of Marl is 0.80 kJ/Kg K and that of Latite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Marl is heat resistant, impact resistant whereas Latite is heat resistant, pressure resistant.
