Formation

Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

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 Basalt and Taconite

Here you can know more about Basalt and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basalt and Taconite consists of mineral content and compound content. The mineral content of Basalt includes 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 Basalt vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Basalt is available in black, brown, light to dark grey colors whereas, Taconite is available in red, reddish brown colors. Appearance of Basalt is Dull and Soft and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Basalt vs Taconite. The hardness of Basalt is 6 and that of Taconite is 5.5-6. The types of Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite 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 Basalt is white to grey while that of Taconite is white. The specific heat capacity of Basalt is 0.84 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.Basalt is heat resistant, pressure resistant, wear resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
