	schist schist , metamorphic rock having a foliated, or plated, structure called schistosity in which the component flaky minerals are visible to the naked eye. Schists are distinguished from the other foliated rocks, slates and gneisses, by the size of their mineral crystals; these are larger than those... Read more
	Precambrian era Precambrian name of a major division of geologic time (see Geologic Timescale , table), from c.5 billion to 570 million years ago. It is now usually divided into the Archean and Proterozoic eons. Precambrian time includes 80% of the earth's history. Precambrian rocks are mostly covered by rock... Read more
	cleavage cleavage tendency of many minerals to split along definite smooth planar surfaces determined by their crystal structure. The directions of these surfaces are related to weaknesses in the atomic structure of the mineral and are always parallel to a possible crystal face. The property of cleavage is... Read more
	gneiss gneiss , coarse-grained, imperfectly foliated, or layered, metamorphic rock . Gneiss is characterized by alternating light and dark bands differing in mineral composition and having coarser grains than those of schist. The light bands of gneiss are generally composed of quartz and feldspar .... Read more
	migmatite Migmatite A migmatite, or "mixed rock" in Greek, is a banded, heterogenous rock composed of intermingled metamorphic and igneous components. Veins, contorted layers, and irregular pods of silica-rich granite occur within the structure of foliated iron and magnesium-rich metamorphic rocks like... Read more
	Hornfels Hornfels Hornfels is a fine-textured metamorphic rock formed by contact metamorphism . Contact metamorphism occurs when a mass of hot magma intrudes into preexisting rock , whether by injecting itself into a crack or by ascending in a large body (e.g., pluton ). Rock in close proximity to... Read more
	slate slate fine-grained rock formed when sedimentary rocks such as shale are metamorphosed by great pressure. Slate splits into perfectly cleaved, broad thin layers; this characteristically regular and planar cleavage is called slaty cleavage. In the formation of slate, pressure causes the flaky... Read more
	Black Hills BLACK HILLS BLACK HILLS, a group of mountains in western South Dakota and northeastern Wyoming. The hills were formed by an upthrust of rock dating to the Archean geologic eon through the overlying strata to a maximum height of 7,242 feet above sea level. Harney Peak, the highest point, is the... Read more
	Phyllite Phyllite Phyllite is an intermediate-grade, foliated metamorphic rock type that resembles its sedimentary parent rock , shale, and its lower-grade metamorphic counterpart, slate . Like slate, phyllite can be distinguished from shale by its foliation, called slaty cleavage, and its brittleness,... Read more
	talc talc mineral ranging in color from white through various shades of gray and green to the red and brown of impure specimens, translucent to opaque, and having a greasy, soapy feel. It is a hydrous silicate of magnesium, Mg 3 Si 4 O 10 (OH) 2 , and usually contains small quantities of nickel, iron,... Read more
