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.
Granophyre 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.

More about Taconite and Granophyre
Here you can know more about Taconite and Granophyre. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Granophyre consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Granophyre, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Granophyre is available in black, grey, orange, pink, white colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Granophyre is Veined or Pebbled. Properties of rock is another aspect for Taconite vs Granophyre. The hardness of Taconite is 5.5-6 and that of Granophyre is 6-7. The types of Taconite are Iron formation whereas types of Granophyre are Intermediate intrusive rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite and Granophyre is white. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Granophyre is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Taconite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Granophyre is heat resistant, wear resistant.
