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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
