Formation

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.   
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
