Formation
Hornblendite 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.

More about Hornblendite and Marl
Here you can know more about Hornblendite and Marl. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Marl consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite 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 Hornblendite vs Marl, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Marl is available in beige, brown, green, grey, white colors. Appearance of Hornblendite is Foliated and that of Marl is Rough and Dull. Properties of rock is another aspect for Hornblendite vs Marl. The hardness of Hornblendite is 6-7 and that of Marl is 2-3. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite 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 Hornblendite is white to grey while that of Marl is white. The specific heat capacity of Hornblendite is Not Available 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.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Marl is heat resistant, impact resistant.
