Magma
| Earth Science |
- Molten rock beneath the surface of the earth.
- Molten material generated with the crust or upper mantle from which igneous rocks are derived by solidifica- tion, and that is capable of intrusion at depths in the crust or extrusion at the surface as lava or a pyroclastic ash flow.
- Molten rock material formed within the earth. solidifies at or near the
- Molten rock within the earth, from which igneous rock is formed by cooling.
- The hot fluid matter within the earth`s crust that is capable of intrusion or extrusion and that produces igneous rock when cooled.

Магма, русский
- (от греч . magma - густая мазь), расплавленная масса преимущественно силикатного состава, образующаяся в глубинных зонах земли. при внедрении магмы в земную кору или при ее излиянии на поверхность земли формируются магматические горные породы. магма периодически образует отдельные очаги в пределах разных по составу и глубинности оболочек земли. главные типы магмы - ультраосновная, основная (базальтовая) и кислая (гранитная); в редких случаях магма имеет щелочно-карбонатный и (или) сульфидный состав.
- Расплавленная огненно-жидкая масса, возникающая в пределах земной коры или на большей глубине и дающая при подъеме и застывании магматические горные породы.

Solidifica, английский
Pyroclastic, английский
- Pertaining to fragmented (clastic) rock material formed by a volcanic explosion or ejection from a volcanic vent.
- An igneous rock composed of angular rock fragments that originate from a volcanic explosion.
- (adj.) pertaining to clastic rock particles produced by explosive, aerial ejection from a volcanic vent. such materials may accumulate on land or under water. compare - epiclastic, volcaniclastic, clastic. g. smith & hp
- General term for any rock composed of material ejected explosively from

Glacial ice, английский
Naturally occurring ice which exhibits internal plastic flow and deformation.
Tephra, английский
- Materials of all types and sizes that are erupted from a crater or volcanic vent and deposited from the air.
- A collective, general term for any and all clastic materials, regardless of size or composition, ejected from a vent during a volcanic eruption and transported through the air; including ash [volcanic; < 2 mm], blocks [volcanic; > 64 mm], cinders [volcanic; 2 - 64 mm], lapilli [2 - 76 mm & specific gravity > 2.0], pumice [> 2 mm & specific gravity < 1.0], and scoria [> 2 mm & specific gravity < 2.0]. tephra, unlike many volcaniclastic terms, does not denote properties of composition, vesicularity, or grain size. sw
