Amphibolite : A crystalline, coarse-grained rock, containing amphibole as an essential constituent, together with feldspar and frequently garnet. Like hornblende schist, amphibolite is formed by regional metamorphism of basic igneous rocks, but is not foliated.
Amphibole : An important group of dark-coloured, rock-forming silicate minerals, including hornblende, the commonest.
Amber: Fossilized resin or tree sap that is appreciated for its vivid colour, usually reddish-orange to gold or yellow.
Alluvium : Soil or sediments deposited by a river or other running water.
Alluvial fan : A fan-shaped deposit formed where a fast flowing stream flattens, slows, and spreads typically at the exit of a canyon onto a flatter plain.
Allochthon : A fossil, sediment, or rock that was formed elsewhere and later transported into the location where it is presently found, usually by low angle thrust faulting. An object of this type is referred to as allochthonous. Contrast autochthon.
Alkaline rock : A type of rock characterized by a high content of Na2O and K2O relative to the other oxides. They occur throughout the range from ultrabasic to acid, but have their strongest expression in the acid-intermediate part of the range.
Alkaline : A highly basic substance that dissolves in water.
Albite : The end member of the plagioclase group of minerals, ideally consisting of silicates of sodium and aluminium, but commonly containing small quantities of potash and lime in addition. Compare barbierite.
Aggregate : A mass consisting of rock or mineral fragments.
Agglomerate : An indurated rock built of large angular rock fragments embedded in an ashy matrix and resulting from explosive volcanic activity. Occurs typically in volcanic vents.
Aftershock : A small earthquake that follows a main shock.
Acid rock : The groups ultrabasic, basic, intermediate and acid constitute a series with progressively increasing SiO2 content.
Achnelith : A small, glassy volcanic bomb, sphere, dumbbell and droplet shapes resulting from very liquid magma.
Accretion : A process by which material is added to a tectonic plate or landmass.
Accident : A sudden discontinuity of ground, such as fault of great thickness, bed or lentil of unstable ground.
Absolute dating : The process of determining a specific date (in years or some other unit of time) for an archaeological, geological or paleontological site or artifact.
Abyssal plain : Flat or very gently sloping areas of the deep ocean basin floor.
