	Metamorphic Rock - MSN Encarta
		The other two groups are igneous rocks, which form when magma or molten lava solidifies, and sedimentary rocks, which form when wind or water deposit sediments and the sediments become compacted.
		When underground magma flows through a crack (called a dike) into areas of surrounding solid rock (known as country rock), there is a significant difference between the temperature of the magma and the temperature of the surrounding rock.
		Rocks that are buried deep beneath many layers of rock experience lithostatic (Greek lithos, “rock”; statikos, “in place”) pressure, which causes the rocks to compress into a smaller, denser form.

		That study focused on a green and white layered rock known as a banded iron formation, thought to be layers of sediment that were deposited on a long lost sea floor.
		But Fedo has a different explanation of the rock's makeup, which he says has been influenced by a lot of complex events over billions of years that have caused the rocks to be stressed, stretched and deformed.
		A chemical study of the rocks shows their composition to be similar to a primitive type of rock called komatiite, related to basalt, which forms when molten rock solidifies.

	Geologic formation - Wikipedia, the free encyclopedia
		Formations were initially described to be the essential geologic time markers based on relative ages and the law of superposition.
		Modern revision of the geologic sciences has restricted Formations to lithologies, because lithological units are formed by depositional environments, some of which may persist for hundreds of millions of years and will transgress chronostratigraphic intervals or fossil-based methods of correlating rocks.
		Formations must be able to be delineated at the scale of geologic mapping practiced in the region.

	Rock formation - Wikipedia, the free encyclopedia
		Rock formation in general refers to specific sedimentary strata or other rock unit in stratigraphic and petrologic studies.
		Sedimentary rocks are created from bits of rocks that have broken off other rocks by wind or water erosion, and deposited by wind, ice, or water.
		Metamorphic rocks are created by rocks that have evolved into another kind of rock, usually by heat and pressure.

	Grand Hikes: Grand Canyon Geology Overview
		Rocks in the Vishnu Group were initially laid down on the sea floor and were composed of quartz rich sands, silts and clays, which were interspersed with ashes, lava flows and feeder dikes associated with a volcanic chain of offshore islands.
		The Vishnu Group rocks are contemporaneous with the oldest known rocks throughout Arizona and the evidence and geologic record afforded by older rocks elsewhere on the Earth is so fragmented and incomplete as to render interpretations highly speculative and debatable.
		Vishnu Group rocks were exposed at the erosion surface as the mountainous region and overlying rocks were eroded away and reduced to a hilly plain.

	How did the oil get into the rock? How can the oil get out?
		The rock in question is diatomite, made of countless silica skeletons of microscopic aquatic plants.
		Seeking a theoretical understanding of the structure and mechanical properties of oil-bearing rocks, one based on fundamental physical principles, Silin and Patzek, with their colleague Guodong Jin of the University of California at Berkeley, have used computer modeling to study how sediments become rocks in the first place.
		Their model is unusual because it incorporates the dynamic processes of sedimentation and compaction, including gravity, contact forces, friction between grains and with the surrounding fluids -- all the ways that grains of different size and composition may move and interact.

	Rock Formations
		Sedimentary rocks are formed from bits of rock that have been broken off other rocks by wind or water erosion, and deposited in their current position by wind or water.
		If a sedimentary rock formation happens to contain a 1956 Chevy, then you know that the rock formation was created by a flood or sandstorm that occurred in 1956 or later.
		If you are going to date a sedimentary rock formation by a fossil, you need some way of knowing when the critter lived, and you need some way of knowing that the fossil wasn’t already fossilized when the rock layer was formed.
