Definition
Granophyre is a type of granitic rock which consists of intergrown feldspar and quartz crystals in a medium to fine grained groundmass
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica

Archaeological Significance
Formation
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.
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 Granophyre and Taconite
Here you can know more about Granophyre and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granophyre and Taconite consists of mineral content and compound content. The mineral content of Granophyre includes Hornblade, Orthoclase, Plagioclase, Quartz 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 Granophyre vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Granophyre is available in black, grey, orange, pink, white colors whereas, Taconite is available in red, reddish brown colors. Appearance of Granophyre is Veined or Pebbled and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Granophyre vs Taconite. The hardness of Granophyre is 6-7 and that of Taconite is 5.5-6. The types of Granophyre are Intermediate intrusive rock whereas types of Taconite are Iron formation.
