Where do minerals form?
Minerals form as parts of rocks, either when the rock was created or later. Minerals grow as components of igneous, sedimentary, or metamorphic rocks and can sometimes be found more than one type of rock. Some minerals crystallize from hot water moving through the rocks long after the host rock formed. The most impressive minerals specimens grow in open spaces created by gas bubbles, fissures or the decay of fossils. Minerals found in igneous rocks cooled and hardened from molten liquid. Minerals in sedimentary rocks are bits of older rocks redeposited by water, wind or glaciers or are directly precipitated from water. As igneous or sedimentary rock are transformed by intense heat and pressure, metamorphic minerals form. Minerals typically found in New York rocks. IGNEOUS ROCKS: Quartz, feldspar, muscovite, biotite, pyroxene, amphibole. SEDIMENTARY ROCKS: Quartz, salt, gypsum, calcite, fluorite, dolomite, sphalerite, celestine. METAMORPHIC ROCKS: Garnet, tourmaline, staurolite, sillima
