5.1 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.
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
