rock: this is one of the three main rock types, the others being sedimentary and metamorphic rock. (roca ígnea)
rock: Rock that has formed through the deposition and solidification of sediment, especially sediment transported by water (rivers, lakes, and oceans), ice (glaciers), and wind. Sedimentary rocks are often deposited in layers, and frequently contain fossils. (roca sedimentaria).
rock: these types of rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock, protolith (protolito) is subjected to heat and pressure, (temperatures greater than 150 to 200 °C and pressures of 1,500 bars) causing profound physical and/or chemical change. The protolith may be sedimentary rock, igneous rock or another older metamorphic rock. (roca metamórfica).
: making less warm (enfriamiento).
: It is a mixture of molten (fundido) or semi molten rock, volatiles and solids that are found beneath the surface of the Earth. (magma).
: In planetary science, volatiles are that group of chemical elements and chemical compounds with low boiling points that are associated with a planet's or moon's crust and/or atmosphere. Examples include nitrogen, water, carbon dioxide, ammonia, hydrogen, and methane, all compounds of C, H, O and/or N, as well as sulfur dioxide. (volátiles)
: It refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. (lava).
: It is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas. (cristalización).
or plutonic rock: these are rocks which are formed from magma that cools and solidifies within the crust of a planet. (roca intrusiva o plutónica).
or volcanic rock: these are rocks which are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust. (roca volcánica o extrusiva).
: solids which are changed from a solid to a liquid state especially by the application of heat. (fundidos).
to : To become liquefied by warmth or heat. (fundir).
: It is a part of a terrestrial planet or other rocky body large enough to have differentiation by density. The interior of the Earth, similar to the other terrestrial planets, is chemically divided into layers. The mantle is a highly viscous layer between the crust and the outer core. (manto).
: It is the outermost solid shell of a rocky planet or natural satellite, which is chemically distinct from the underlying mantle. The crusts of Earth, our Moon, Mercury, Venus, Mars, Io, and other planetary bodies have been generated largely by igneous processes. (Corteza).
: force applied uniformly over a surface. (presión).
(adjective): below; underneath. (bajo).
: the outer face, outside, or exterior boundary of something. (superficie).
: something that takes place. (acontecimiento).
rock: the rock native to an area. (roca caja).
-grained (adjective): describes systems consisting of fewer, larger components than fine-grained systems which have more smaller components (de grano grueso).
eye: sight unassisted by an instrument such as a microscope or telescope. (a simple vista).
to : to force into. (introducir).
: It is a large emplacement of igneous intrusive (also called plutonic) rock that forms from cooled magma deep in the Earth's crust. Batholiths are almost always made mostly of felsic or intermediate rock-types, such as granite, quartz monzonite (monzonita de cuarzo), or diorite (diorite). (Batolito).
: It is a discordant igneous intrusion having a surface exposure of less than 100 km2, differing from batholiths only in being smaller. Most stocks are probably the cupolas of hidden batholiths. Circular or elliptical stocks may have been vents feeding former volcanoes. (stock).
: It is a sheet intrusion (or concordant pluton) that has been injected between two layers of sedimentary rock. The pressure of the magma is high enough that the overlying strata are forced upward, giving the laccolith a dome or mushroom-like form with a generally planar base. (lacolito).
: It is a tabular sheet intrusion (intrusion laminar) that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff (toba volcánica), or even along the direction of foliation in metamorphic rock. The term sill is synonymous with concordant intrusive sheet. This means that the sill does not cut across preexisting rocks in contrast to dikes, which are discordant intrusive sheets which do cut across older rocks. Sills are fed by dikes, except in unusual locations where they form in nearly vertical beds (capas) attached directly to a magma source. (sill).
: It is a type of sheet intrusion referring to any geologic body that cuts discordantly across planar wall rock structures or massive rock formations. Dikes can therefore be either intrusive or sedimentary in origin. (dique).
: The central part of anything. (corazón, centro).
: Greater than others in importance. (principal).
mountain : A series of mountain ridges (crestas) alike in form, direction, and origin. (cordillera, sierra).
: It is a common and widely occurring type of intrusive, felsic (félsica), igneous rock. This rock usually has a medium to coarse-grained texture. Occasionally some individual crystals (phenocrysts) (fenocristales) are larger than the groundmass (matriz), in which case the texture is known as porphyritic (porfírica). A granitic rock with a porphyritic texture is sometimes known as a porphyry (pórfido). These rocks can be pink to gray in color, depending on their chemistry and mineralogy. By definition, granite is an igneous rock with at least 20% quartz by volume. (granito).
(adjective): Having the component parts closely compacted together. (denso).
: The ejection of molten rock, steam, etc., from a volcano. (erupción).
: what something is called. (denominar).
(adjective): Below the surface or level of; beneath. (Bajo).
a black : a (hydrothermal vent ) fissure on the floor of a sea out of which flows water that has been heated by underlying magma. (fumarola).
mid-ocean : Any of several seismically active submarine mountain ranges that extend through the Atlantic, Indian, and South Pacific oceans; each is hypothesized to be the locus (lugar) of seafloor (fondo marino) spreading (extendiéndose). (dorsal meso oceánica).
: It is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to the fast cooling of lava at the surface. It may be porphyritic (porfírica) containing larger crystals in a fine matrix (matriz), or vesicular or frothy (espumoso) scoria (escoria). Unweathered (no erosinonado) basalt is black or grey. By definition, basalt is defined as an aphanitic (afanítica) igneous rock that contains, by volume, less than 20% quartz and less than 10% feldspathoid (feldespatoide) and where at least 65% of the feldspar (feldespato) is in the form of plagioclase (plagioclasa). (basalto).
(adjective): this texture is a volcanic rock texture characterised by a rock being pitted (agujereado, horadado) with many cavities (known as vesicles) at its surface and inside. (vesicular)
: It is a volcanic rock containing many holes or vesicles. It is most generally dark in color (generally dark brown, black or purplish red), and basaltic or andesitic (andesítica) in composition. This rock is relatively low in mass as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice (pumita), all scoria has a specific gravity greater than 1, and sinks in water. The holes or vesicles form when gases that were dissolved in the magma come out of solution as it erupts, creating bubbles in the molten rock, some of which are frozen in place as the rock cools and solidifies. This rock may form as part of a lava flow, typically near its surface, or as fragmental ejecta (ejección) (lapilli, blocks and bombs). (scoria)
: Any of a group of relatively rare minerals that are chemically very similar to feldspars, but have too little silica to qualify as feldspars. (feldespatoide)
(viscous): The extent to which a fluid resists a tendency to flow. (viscosidad).
: A dark viscous syrup obtained during the refining of sugar. (melaza).
to : To move or run smoothly with unbroken continuity. (fluir).
: From a Hawaiian word meaning "smooth, unbroken lava". It is basaltic lava that has a smooth ropy (parecido a una cuerda, fibroso) surface. (lava cordada).
: It is an extrusive igneous, volcanic rock. The mineral assemblage is typically dominated by plagioclase plus pyroxene and/or hornblende. (andesita).
: A cone of this type, or a scoria cone, is a steep conical hill of tephra (volcanic debris) that accumulates around and downwind (a favor del viento) from a volcanic vent (chimenea volcánica) (Cono de cenizas o cono de escoria).
to : to mix or become mixed together. (Entremezclarse).
: A thick syrup produced in refining raw sugar and ranging from light to dark brown in color. (melaza).
(adjective): This word is a term used in geology to refer to silicate minerals, magma, and rocks which are enriched in the lighter elements such as silicon, oxygen, aluminum, sodium, and potassium. (félsico).
: This is an igneous, volcanic (extrusive) rock, of felsic (silica-rich) composition. The mineral assemblage is usually quartz, alkali feldspar (feldespato alcalino) and plagioclase (plagioclasa). Biotite (biotita) and hornblende (hornblenda) are common accessory minerals. (riolita).
(adjective): Having a sharp inclination. (empinado).
: this is fragmental material produced by a volcanic eruption regardless of composition, fragment size or emplacement mechanism. Ash (cenizas) - particles smaller than 2 mm in diameter; lapilli (lapilli) or volcanic cinders - between 2 and 64 mm - and volcanic bombs or volcanic blocks - larger than 64 mm. (tefra)
: This is the word that volcanologists use to refer to airborne fragments from volcanoes. Once clasts have fallen to the ground they remain as tephra unless hot enough to fuse together into pyroclastic rock or tuff. (toba volcánica). (piroclasto)
rock: rocks composed solely or primarily of volcanic materials. (roca piroclastica)
a : It is a type of rock consisting of consolidated volcanic ash ejected from vents during a volcanic eruption. (toba volcánica)
: They are coarse (rugoso) accumulations of large blocks of volcanic material that contain at least 75% bombs. (aglomerado).
: a pyroclastic deposit formed by the high-temperature gas and ash mix of a pyroclastic flow event. (ignimbrita).
(adjective): Very great in area or extent; immense. (extenso).
: It is an amorphous (non-crystalline) solid material. Glasses are typically brittle (quebradizo, frágil) and optically transparent. (vidrio).
: It is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth. (obsidiana).
