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.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
