Определение gabbro в Английский Язык Английский Язык словарь
A name originally given to a kind of serpentine, and now generally used for a coarsely crystalline, igneous rock consisting of lamellar pyroxene and labradorite
Rough, crystalline igneous rock forming much of the Cuillin Ridge in Skye Generally dark brown or black in colour
Any of a group of dark, dense, phaneritic, intrusive rocks that are the plutonic equivalent to basalt
A name originally given by the Italians to a kind of serpentine, later to the rock called euphotide, and now generally used for a coarsely crystalline, igneous rock consisting of lamellar pyroxene (diallage) and labradorite, with sometimes chrysolite (olivine gabbro)
Highly mafic igneous plutonic rock, typically dark in color; rough plutonic equivalent of basalt
Any of several medium-or coarse-grained rocks that consist primarily of plagioclase feldspar and pyroxene. Gabbros are found widely on the Earth and on the Moon. They are sometimes quarried for dimension stone ("black granite"), but the direct economic value of gabbro is minor. Far more important are the nickel, chromium, and platinum minerals that occur almost exclusively in association with gabbroic or related rocks. Magnetite (iron) and ilmenite (titanium) are also found in gabbroic complexes
A coarse grained basic igneous rock The crystals are large as a result of the magma cooling and crystallising slowly deep underground Gabbro is the basic equivalent of the acid granite
1) A dark, massive rock with crystals large enough to be seen with the naked eye This igneous rock formed from magma flowing up and cooling slowly below the surface It is the intrusive equivalent of the extrusive basalt, which would form if the same magma cooled on the surface 2) A large lake on the lower Kawishiwi River
A granular igneous rock composed essentially of calcic plagioclase, a ferromagnesian mineral, and accessory minerals
A fine grained, dark colored, igneous rock consisting primarily of plagioclase, feldspar and pyroxene
A coarse-grained, mafic intrusive rock, composed mainly of the minerals plagioclase, pyroxene and olivine
an extremely rough rock offering good friction grip, the principle rock of the Skye Cuillin glean - a glen glen - valley Grahams, The - a list of Scottish hills between 2000 and 2499 feet high The original list was compiled by Alan Dawson and Fiona Torbet (nee Graham) There are 224 Grahams grid reference - the Ordnance Survey use a system of imaginary squares covering the UK as a reference for pin-pointing any place with great accuracy gully - a channel or ravine
