Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica

Archaeological Significance
Formation
Wehrlite 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.

Wehrlite vs Taconite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Wehrlite vs Taconite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Taconite. Learn more about Wehrlite vs Taconite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Wehrlite and Taconite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Taconite include As dimension stone, Used for flooring, stair treads, borders and window sills..
More about Wehrlite and Taconite
Here you can know more about Wehrlite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Taconite consists of mineral content and compound content. The mineral content of Wehrlite includes 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 Wehrlite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Taconite is available in red, reddish brown colors. Appearance of Wehrlite is Rough and Banded and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Wehrlite vs Taconite. Hardness of Wehrlite and Taconite is 5.5-6. The types of Wehrlite are Ultramafic rock 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 Wehrlite and Taconite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Taconite is 3.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
