|
rock
|
solid materal in the earth's crust that is a natural combination of minerals or other materials
|
|
|
texture
|
how a rock looks and feels base on the sizes of the mineral grains and other particles that compose the rock
|
|
|
petrology
|
the study of rock, their classification, and their history
|
|
|
grain (rock)
|
pieces and particles of minerals crystals, rock fragment and even fossils in a rock that determine its texture
|
|
|
igneous rock
|
having to do with molten or formerly molten earth materials
|
|
|
pegmatite
|
a coarse-grained igneous rock with very large interlocking crystal
|
|
|
porphyry
|
an igneous rock containing a few large mineral grains embedded in a very-fine texture mix
|
|
|
phanerite
|
an igneous rock composed of distinct mineral grains that are small and more or less the same size
|
|
|
aphanitic (rock)
|
a fine-grained igneous rock with crystal too small to see, even with a microscope; often extrusive igneous rock
|
|
|
sedimentary rock
|
a rock made of sediments produced by erosion or chemical precipitation
|
|
|
clast
|
a piece of broken or eroded rock
|
|
|
clastic sedimentary rock
|
a rock made from the eroded fragments of other rocks
|
|
|
non clastic sedimentary rock
|
a sedimentary rock composed of materials that are not clastic erosion sediments
|
|
|
chemical sedimentary rock
|
a rock composed of chemical precipitates; one form of non clastic sedimentary rock
|
|
|
precipitation (chemical)
|
in geology, any process that causes chemical substances dissolved in water to form a solid compounded that settles out of solution
|
|
|
metamorphic rock
|
a igneous, sedimentary, or even another metamorphic rock that seems to have been physically and chemically changed over time by temperature, pressure, or the presence of hydrothermal fluid
|
|
|
regional metamorphism
|
metamorphism that occurred over large areas caused by widespread, regional tectonic forces, heat or pressure
|
|
|
contact metamorphism
|
metamorphism caused mainly by contact with high-temperature magma or lava
|
|
|
dynamic metamorphism
|
metamorphism that occurred when conditions rapidly changed in rocks
|
|
|
foliated metamorphic rock
|
metamorphic rock containing flattened or flaky mineral crystals, giving it a banded or layered appearance
|
|
|
nonfoliated metamorphic rock
|
a metamorphic rock that doesn't have band or layers
|
|
|
rock cycle
|
a naturalistic, old-earth idea that rock is recycled just like nearly every other natural resource
