Glossary of terms for section



Tectonic Plates -

Sedimentary rocks - Rock formed from accumulations of sediment, which may consist of rock fragments of various sizes, remains or products of animals or plants, products of chemical action or of evaporation, or mixtures of these; stratification is single most characteristic feature of sedimentary rocks, which cover about 75 percent of land areaxxxi

Erosion - Movement of material from one place to another on earth's surface; agents of movement include gravity, water, ice, and windxxxii

Deposition -

Lithification - Process by which unconsolidated rock-forming materials are converted into a consolidated or coherent statexxxiii

Shale –

Sandstone

Limestone

Orogeny – Process by which mountain structures developxxxiv

Orogen -

Eustacy - Change in sea level produced entirely by increase or decrease in amount of water in oceans; hence of worldwide proportionsxxxv

Forarc basin - A depression in the sea floor located between an accretionary wedge and a volcanic arc in a subduction zone, and lined with trapped sedimentxxxvi

Backarc basin - A depression landward of a volcanic arc in a subduction zone, which is lined with trapped sediment from the volcanic arc and the plate interiorxxxvii

Province -

Folds - Bend, flexure, or wrinkle in rock produced when rock was in a plastic statexxxviii

Syncline - A configuration of folded, stratified rocks in which rocks dip downward from opposite directions to come together in a troughxxxix

Anticline - A configuration of folded, stratified rocks in which rocks dip in two directions away from a crest, as principal rafters of a common gable roof dip away from ridgepole; the "ridgepole," or crest, is called the hinge line or axisxl

Faults - Surface of rock rupture along which has been differential movementxli

Normal - Fault in which hanging wall appears to have moved downward relative to footwall; opposite of thrust fault; also called gravity faultxlii

Reverse - Fault in which hanging wall appears to have moved upward relative to footwall; contrast with normal, or gravity fault; also called thrust faultxliii

Accretionary prism – A mass of sediment and oceanic lithosphere that is transferred from a subducting plate to the less dense, overriding plate with which it convergesxliv

Convergent margin – Boundary between two plates moving toward each otherxlv

Divergent margin - Boundary between two plates moving apart; new oceanic-type lithosphere is created at the openingxlvi

Active margin -

Passive margin - A border that lies between continental and oceanic lithosphere, but is not a plate margin, marked by lack of seismic and volcanic activityxlvii

Subduction - Act of one tectonic unit's descending under another (commonly slab of lithosphere)xlviii
