Definition
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

Archaeological Significance
Formation
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

More about Mudstone and Basanite
Here you can know more about Mudstone and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Basanite consists of mineral content and compound content. The mineral content of Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Basanite , the texture, color and appearance plays an important role in determining the type of rock. Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Mudstone is Rough and Dull and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Mudstone vs Basanite . The hardness of Mudstone is 2-3 and that of Basanite is 7. The types of Mudstone are Marl, Shale and Argillite whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Basanite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Basanite is 0.74 kJ/Kg K.
