Formation

Formation
Nephelinite 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.

Nephelinite vs Marl 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 Nephelinite and Marl Reserves. Nephelinite is a fine-grained or aphanitic igneous rock made up almost entirely of nepheline and clinopyroxene (variety augite).. Marl is an unconsolidated sedimentary rock consisting of clay and lime. 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 Nephelinite vs Marl information and Nephelinite vs Marl characteristics in the upcoming sections.

Nephelinite vs Marl Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Nephelinite vs Marl characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Nephelinite and Properties of Marl. Learn more about Nephelinite vs Marl in the next section. The interior uses of Nephelinite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Marl include Decorative aggregates and Floor tiles. Due to some exceptional properties of Nephelinite and Marl, they have various applications in construction industry. The uses of Nephelinite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Marl include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.

More about Nephelinite and Marl

Here you can know more about Nephelinite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Nephelinite and Marl consists of mineral content and compound content. The mineral content of Nephelinite includes Clinopyroxene, Nepheline, Plagioclase and mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Nephelinite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Nephelinite is available in black, brown, colourless, green, grey, white colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Nephelinite is Skeletal and that of Marl is Rough and Dull. Properties of rock is another aspect for Nephelinite vs Marl. The hardness of Nephelinite is 6.5 and that of Marl is 2-3. The types of Nephelinite are Peralkaline Nephelinite whereas 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. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Nephelinite and Marl is white. The specific heat capacity of Nephelinite is 0.88 kJ/Kg K and that of Marl is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Nephelinite is heat resistant whereas Marl is heat resistant, impact resistant.
