Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.

Basanite 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. Basanite vs Marl characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Basanite and Properties of Marl. Learn more about Basanite vs Marl in the next section. The interior uses of Basanite include Decorative aggregates and Homes whereas the interior uses of Marl include Decorative aggregates and Floor tiles. Due to some exceptional properties of Basanite and Marl, they have various applications in construction industry. The uses of Basanite in construction industry include Arrowheads, Construction aggregate, Cutting tool, Spear points and that of Marl include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Basanite and Marl
Here you can know more about Basanite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Marl consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, 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 Basanite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Basanite is Glassy or Pearly and that of Marl is Rough and Dull. Properties of rock is another aspect for Basanite vs Marl. The hardness of Basanite is 7 and that of Marl is 2-3. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite 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 Basanite and Marl is white. The specific heat capacity of Basanite is 0.74 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.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Marl is heat resistant, impact resistant.
