5 Formation
5.1 Formation
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.
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.

Pyroxenite 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 Pyroxenite and Marl Reserves. Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine. 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 Pyroxenite vs Marl information and Pyroxenite vs Marl characteristics in the upcoming sections.
