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.

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
