Archaeological Significance
Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
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 Whiteschist and Taconite
Here you can know more about Whiteschist and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Taconite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Whiteschist vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Taconite is available in red, reddish brown colors. Appearance of Whiteschist is Banded and Foilated and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Whiteschist vs Taconite. The hardness of Whiteschist is 1.5 and that of Taconite is 5.5-6. The types of Whiteschist are - 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 Whiteschist and Taconite is white.
