Formation

Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

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.

More about Aplite and Marl

Here you can know more about Aplite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Marl consists of mineral content and compound content. The mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Aplite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Aplite is available in black, grey, orange, pink, white colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Aplite is Veined or Pebbled and that of Marl is Rough and Dull. Properties of rock is another aspect for Aplite vs Marl. The hardness of Aplite is 6.5 and that of Marl is 2-3. The types of Aplite are Igneous rock 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 Aplite and Marl is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Marl is 0.80 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Aplite is heat resistant, wear resistant whereas Marl is heat resistant, impact resistant.
