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.

Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
