Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

More about Taconite and Basanite
Here you can know more about Taconite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Basanite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, 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 Taconite vs Basanite , the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Taconite vs Basanite . The hardness of Taconite is 5.5-6 and that of Basanite is 7. The types of Taconite are Iron formation whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite.
