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
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica

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.
Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.

More about Mudstone and Taconite
Here you can know more about Mudstone and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mudstone and Taconite 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 Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Mudstone vs Taconite, 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, Taconite is available in red, reddish brown colors. Appearance of Mudstone is Rough and Dull and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Mudstone vs Taconite. The hardness of Mudstone is 2-3 and that of Taconite is 5.5-6. The types of Mudstone are Marl, Shale and Argillite whereas types of Taconite are Iron formation. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mudstone and Taconite is white. The specific heat capacity of Mudstone is 0.39 kJ/Kg K and that of Taconite is 3.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mudstone is heat resistant, impact resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
