Archaeological Significance
Formation
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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

More about Taconite and Jasperoid
Here you can know more about Taconite and Jasperoid. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Jasperoid consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Jasperoid, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Jasperoid is available in black, brown, green, grey, pink, white colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Jasperoid is Glassy or Pearly. Properties of rock is another aspect for Taconite vs Jasperoid. The hardness of Taconite is 5.5-6 and that of Jasperoid is 3.5-4. The types of Taconite are Iron formation whereas types of Jasperoid are -.
