Formation

Formation
The banded iron layers are formed in sea water when oxygen is released by photosynthetic cyano-bacteria. The oxygen then combines with dissolved iron in ocean to form insoluble iron oxides, which precipitated out, forming a thin layer of banded iron formation on ocean floor.   
Monzogranite 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.

All about Banded iron formation and Monzogranite Properties

Know all about Banded iron formation and Monzogranite properties here. All properties of rocks are important as they define the type of rock and its application. Banded iron formation belongs to Sedimentary Rocks while Monzogranite belongs to Igneous Rocks.Texture of Banded iron formation is Banded, Trellis whereas that of Monzogranite is Porphyritic. Banded iron formation appears Layered, Banded, Veined and Shiny and Monzogranite appears Veined or Pebbled. The luster of Banded iron formation is earthy while that of Monzogranite is dull to grainy with sporadic parts pearly and vitreous. Banded iron formation is available in red, reddish brown colors whereas Monzogranite is available in black, grey, orange, pink, white colors. The commercial uses of Banded iron formation are as a touchstone, cemetery markers, creating artwork and that of Monzogranite are cemetery markers, commemorative tablets, creating artwork, curling, tombstones.
