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.

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
