Iron Ore Veins from Sedimentary and Igneous Rocks 

We continue with our main lesson block in Mineralogy with a two part lesson on the formation of iron ore veins in banded iron formations and iron oxide deposits in both sedimentary and igneous rocks. This lesson was suppose to complement the lesson we did on limestone and the production of cement, mortar and concrete from the chemical processing of limestone. However, once I started the illustration for this lesson, I realized that I might have drawn banded iron formations in sedimentary rock rather than igneous rock. Instead of turning this lesson into iron ore from sedimentary rock (because I wanted to devote another lesson on the formation of iron oxide in precambrian oceans), I opted to add another illustration to show how iron is formed through volcanic activity through the precipitation of minerals based on surrounding rock and the presence of water.
