Breccia, английский
- Angular fragments of material, commonly formed by physical weathering processes or explosive volcanic activity.
- Any stone composed of angular fragments embedded and consolidated in a finer ground. numerous marbles owe their distinctive appearance to brecciation.
- A coarse-grained rock of sedimentary or igneous origin that is composed of angular rock fragments held to- gether by a mineral cement or fine-grained matrix.
- Any rock formation essentially composed of uncemented, or loosely consolidated, small angular-shaped fragments. compare broken ground.
- A fragmental rock whose components are angular and therefore not waterworn. there are friction or fault breccias, talus breccias, and eruptive breccias. compare conglomerate.
- A coarse-grained, clastic rock composed of angular rock fragments (larger than 2 mm) commonly bonded by a mineral cement in a finer-grained matrix of varying composition and origin. the consolidated equivalent of rubble. compare - conglomerate. gsst
- Coarse-grained rock composed of angular broken rock fragments held together by

Brecciation, английский
Igneous, английский
- A rock that solidified from molten or partially molten magma (the term is also applied to the geologic processes leading to or related to the formation of igneous rocks).
- In petrology, rock formed by solidification of a molten material. those solidifying deep within the earths crust are plutonic; those ejected and solidifying on the surface are volcanic.

Igneous metamorphism, английский
Igneous province, английский
A region of the earth’s surface and shallow subsurface that contains features related to volcanoes, hot magma, or rocks that contain magmatic and/or naturally radioactive heat. these geological settings are obvious targets for geothermal exploration. a sub-category of igneous province is a magmatic hot spot of the earth’s crust, for example the iceland and hawaii hot spots. a few documents use “magmatic tectonic province,” but this term is geologically ambiguous and not recommended.
Igneous rock, английский
- A class of rock formed by change of the molten material to the solid state; generally termed granite if coarse-grained.
- Igneous
- Rock formed by cooling and solidification from magma, and that has not been changed appreciably by weathering since its formation; major varieties include plutonic and volcanic rocks. examples: andesite, basalt, granite. compare - intrusive, extrusive, metamorphic rock. gsst & hp
- A rock mass formed by the solidification of magma within the earth`s crust or on its surface. it is classified by chemical composition and grain size. granite is an igneous rock. rsmyth.shr.glossary.doc
Igneous rocks, английский
Rocks, which have solidified from liquid melts, or magmas.
