igneous rocks- rocks that are formed from melted minerals. ore-a rock that has a large amount of minerals.
Chemical sedimentary rock is created by precipitation of minerals out of, or evaporation from, saturated solutions that are high in dissolved minerals. Rock gypsum and rock salt are two examples.
