Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

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

The uses of Taconite in construction industry include As dimension stone, Used for flooring, stair treads, borders and window sills. and that of Basaltic Trachyandesite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Taconite and Basaltic Trachyandesite
Here you can know more about Taconite and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Basaltic Trachyandesite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Basaltic Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Taconite vs Basaltic Trachyandesite. The hardness of Taconite is 5.5-6 and that of Basaltic Trachyandesite is 6. The types of Taconite are Iron formation whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite is white while that of Basaltic Trachyandesite is white to grey.
