basaltic 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. of or relating to or containing basalt; "basaltic magma is fluid"
  2. (basalt) the commonest type of solidified lava; a dense dark grey fine-grained igneous rock that is composed chiefly of plagioclase feldspar and pyroxene
  3. Basalt (or) is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey.
  4. (basalt) A hard rock of varied mineral content; volcanic in origin, it makes up much of the Earth's crust; A type of unglazed pottery
  5. (Basalt) Volcanic rock (or lava) that characteristically is dark in color, contains 45 to 54 percent silica, and generally is rich in iron and magnesium.
  6. (basalt) a dense-textured (aphanitic), igneous rock relatively high in iron and magnesia minerals and relatively low in silica, generally dark grey to black, and feldspathic; a general term in contradistinction to felsite, a light-colored feldspathic and highly siliceous rock of similar texture ...
  7. (Basalt) Dark-colored, low-silica (less than 53 percent SiO2), low viscosity volcanic rock that is relatively fluid when molten; eruptions of basalt are generally non explosive and tend to produce relatively long thin lava flows like those common in Hawaii.
  8. (Basalt) A general term for dark-colored iron- and magnesium-rich igneous rocks, commonly extrusive, but locally intrusive. It is the principal rock type making up the ocean floor.
  9. (Basalt) A dark, fine-grained igneous rock formed by cooling of iron- and magnesium-rich lava above the surface of the earth. Basalt is the main component of the oceanic crust of the earth.
  10. (basalt) hard black volcanic rock formed by lava that has flowed from volcanoes or cracks in the Earth's crust and hardened. photo
  11. (basalt) (ba SAWLT) — type of rock formed when lava cools quickly
  12. (Basalt) Dark colored, fine-grained volcanic igneous rock.
  13. (basalt) a dense black or grey igneous rock
  14. (Basalt) a very common igneous rock. In fact, it is the most common rock in the Earth's crust. Almost all oceanic crust is made of basalt and basalt is a common extrusion from many volcanic regions around the world. ...
  15. (Basalt (Basaltic Lava)) The least viscous (most runny) kind of lava.  Basalt is black, reddish brown or gray when it cools.  Sometimes you can see a few crystals (phenocrysts) spread out in a piece of basalt, but most of the minerals are often too small to see without help from a microscope.
  16. (Basalt (basaltic magmatism)) A type of igneous igneous rock with a basic composition. Strictly the term is used only for lavas, erupted at the earth's surface. ...
  17. (Basalt(ic)) Outcropping rocks of high heavy metal and zeolite content comprising the coastal hills of Cos. Antrim and Londonderry; drainage waters and derivative soils are of high base status
  18. (Basalt) (basaltes) A type of vitrified black stoneware developed by Josiah Wedgwood in the 1760s, inspired by ancient Greek pottery.
  19. (Basalt) A dark igneous rock. Basalt originates from lava that has extruded onto the surface of the Earth. Therefore the lava has cooled quickly, forming small crystals.
  20. (Basalt) A dark volcanic rock, often with a glassy appearance, composed chiefly of plagioclase, pyroxene, and olivine.
  21. (Basalt) A dark, dense volcanic rock difficult to shape.
  22. (Basalt) A fine-grained basic igneous rock occurring in dykes, sills and lava-flows; essential minerals are plagioclase felspar and augite. Dark grey to black in colour; relative density 2.8-3.3; aggregate crushing value 7-25.
  23. (Basalt) A fine-grained basic volcanic rock, which can be used in aggregate production, similar in composition to gabbros.
  24. (Basalt) A fine-grained, dense, igneous rock, but unlike granites contains little or no quartz or feldspars. The colors of basalts are very dark green to black and often sold as granites.
  25. (Basalt) A type of fluid magma with low silica content. Forms dark coloured rock (often red or black), such as the scoria cones of Auckland.
