Geology related definitions
aa: a lava flow with a rubbly surface.
ablation: the removal of ice at the toe of a glacier by melting, sublimation and/or calving.
absolute plate velocity: the movement of a plate relative to a fixed point in the mantle.
abyssal plan: a broad, relatively flat region of the ocean that lies at least 4.5 km below sea level.
adiabatic cooling /heating: cooling or heating of a body of matter without the addition or subtraction of thermal energy (heat).
allochem: ooids, peloids, oncolites, pellets, fossil or pre-existing carbonate fragments found in carbonate rocks.
alluvium: unconsolidated geological materials accumulated as a result of streams and rivers pouring out to sea, larger water deposit or land.
anticline: a fold with an arch-like shape in which the limbs dip away from the hinge.
aquiclude: asediment or rock that do not transmit water.
aquifer: sediment or rock that transmit water.
aquitard: sediment or rock that transmit water slowly therefore retards the motion of the water.
bar: (1) sheet or elongate lens or mound of alluvium; (2) unit of air pressure equals to 1 atm.
contact metamorphism: around intrusive igneous rocks as a result of the temperature increase caused by the intrusion of magma into cooler country rock causing the country rock surrounding the magma to under go metamorphism.
Darcy's law: mathematical equation where volume of water passing through a specified area of material at a given time, depends on the material's permeability and hydraulic gradient.
decompression melting: melting of rocks that occurs when hot mantel rock rises to shallower depths in the Earth causing pressure to decrease while temperature do not change.
dike: a tabular aka wall-shaped intrusion of rock that cuts across the layering of country rock.
dip-slip fault: a fault in which sliding occurs up or down the slope (dip) of the fault.
Doppler effect: phenomenon which the frequency of wave energy appears to change when a moving source of wave energy passes an observer.
electron affinity: the energy released when an electron added to an atom or molecule. also readGeochemistry
eolian (transport): a type of transport where sediment particles are transported by wind.
eon: larget subdivision of geologic time.
erosion: : grinding away and removal of Earth's surface materials by moving water, air, or ice.
floodplain: the flat land on either side of a stream that becomes covered with water during a flood.
fluvial deposit: sediment deposited in a stream channel, along a stream a stream bank, or on a floodplain.
foliation: layering formed as a result of the alignment of mineral grains, or of compositional banding in a metamorphic rock.
geology: study of the Earth (sometimes other planets), its history and nature of materials. (I am NOT sure about this one!)
hydraulic conductivity: K in Darcy's law, where permeability of the rocks and fluid's viscosity is used to calculate it.
igneous rock: hot molten rock of magma or lava solidify as a result of cooling to form a rock.
lava: hot molten rock on the Earth's surface.
magma: hot molten rock under the Earth's surface.
metamorphic rock: forms due to increase in pressure and temperature on preexisting rocks.
mineral: "a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic defined chemical composition, highly ordered atomic structure, and specific physical properties." (according to the professional standards)
oceanic crust: composed of gabbro and basalt, an overlain by sediment beneath the oceans.
ore: rocks containing native metals or ore minerals.
ore deposit: an area with a significant accumulation of ore.
oxbow lake: a mender that has been cut off yet remains filled with water.
peat: compacted partially decayed vegetation accumulating beneath a swamp.
PPL: plane polarized light; used in mineralogy and other areas where microscopes are used to identify minerals. Most minerals behaves differently in XPL compared to PPL. also readXPL
REE: rare earth elements; 17 elements found on Earth which includes, Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu. also readREE
rock: a stupid rock? I have no idea what's a rock and what is not? I will update this soon. Stupid f**king rocks.
sedimentary rock: forms due to cementation of preexisting rock fragments and/or by precipitation of minerals out of solutions at or near the Earth's surface.
state function: depends only on the current state of a system and is independent of the path which the state was achieved. Ex. internal energy, enthalpy, entropy.
structure: from the Latin word Stracere which means to build. It is defined as a fundamental, tangible or intangible notion referring to the recognition, observation, nature, and permanence of patterns and relationships of entities.
structural geology: the study of deformation of lithospheric structures in three demention (3D) by scientific means to underrstand the geometry, distribution and formation.
syncline: a trough-shaped fold whose limbs dip toward the hinge.
tectonics: the structures within the lithosphere of the Earth, which has several 'broken' pieces of crust.
TOT: tetraheral - octahedral - tetrahedral. Related to silicate structure.
XPL: cross-polarized light; used in mineralogy and other areas where microscopes are used to identify minerals. Most minerals behaves differently in XPL compared to PPL. also readPPL
