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.
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.

More about Marl and Diorite
Here you can know more about Marl and Diorite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marl and Diorite consists of mineral content and compound content. The mineral content of Marl includes Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz and mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Marl vs Diorite, 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, Diorite is available in black, brown, light to dark grey, white colors. Appearance of Marl is Rough and Dull and that of Diorite is Shiny. Properties of rock is another aspect for Marl vs Diorite. The hardness of Marl is 2-3 and that of Diorite is 6-7. 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 Diorite are Not Available. 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 Diorite is bluish black. The specific heat capacity of Marl is Not Available and that of Diorite is Not Available. 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 Diorite is heat resistant, pressure resistant, wear resistant.
