Definition

Marl is an unconsolidated sedimentary rock consisting of clay and lime

Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

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.

Shoshonite 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 Shoshonite 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 Shoshonite Reserves. Marl is an unconsolidated sedimentary rock consisting of clay and lime. Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass. 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 Shoshonite information and Marl vs Shoshonite characteristics in the upcoming sections.

More about Marl and Shoshonite

Here you can know more about Marl and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marl and Shoshonite consists of mineral content and compound content. The mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz and mineral content of Shoshonite includes Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Marl vs Shoshonite, 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, Shoshonite is available in brown- black, dark brown colors. Appearance of Marl is Rough and Dull and that of Shoshonite is Dull. Properties of rock is another aspect for Marl vs Shoshonite. The hardness of Marl is 2-3 and that of Shoshonite is 6. 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 Shoshonite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marl is white while that of Shoshonite is white to grey. The specific heat capacity of Marl is 0.80 kJ/Kg K and that of Shoshonite is 0.79 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 Shoshonite is heat resistant, pressure resistant.
