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.

Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
