Archaeological Significance
Formation
Theralite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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 Theralite and Taconite
Here you can know more about Theralite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Theralite and Taconite consists of mineral content and compound content. The mineral content of Theralite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Theralite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Theralite is available in dark grey to black colors whereas, Taconite is available in red, reddish brown colors. Appearance of Theralite is Veined and Shiny and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Theralite vs Taconite. The hardness of Theralite is 7 and that of Taconite is 5.5-6. The types of Theralite are Teschenite and Essexite 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 Theralite and Taconite is white.
