Where molten basalt cools rapidly, as at the earth''s surface, finegrained rocks are formed. Basalt may be compact or vesicular,, porous because of gas bubbles contained in the lava while it is solidifying. If the vesicles become subsequently filled with secondary minerals,, quartz or calcite, the rock is called amygdaloidal basalt.
Basalt is a very abundant volcanic rock. A basalt boulder is simply a large chunk of basalt rock.
A. Basalt fiber is made from a single material, crushed basalt, from a carefully chosen quarry source and unlike other materials such as glass fiber, essentially no materials are added. The basalt is simply washed and then melted. The manufacture of basalt fiber requires the melting of the quarried basalt rock.
Basaltic lava is another term for mafic lava is molten rock that is enriched in iron and magnesium and low in silica. When mafic lava cools on the earth''s surface, it forms basalt ...

Metamorphic rocks are formed by subjecting any rock type—sedimentary rock, igneous rock or another older metamorphic rock—to different temperature and pressure conditions than those in which the original rock was formed. This process is called metamorphism, meaning to "change in form".The result is a profound change in physical properties and chemistry of the stone.

Basalt is a major rock type that occurs in virtually every tectonic setting. Basalt is clearly the most common volcanic rock on Earth and basaltic rocks (including gabbro, diabase and their metamorphosed equivalents) are the most common rocks in the crust is also common on the Moon and other rocky planets of the Solar System.
Rock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is comprised and typically form recognizable and mappable volumes. Rocks are commonly divided into three major classes according to the processes that resulted in their formation.

Basalt rock is one of the most abundant components in the Earth''s crust, and is commonly formed due to lava flow. In this article, we will take a look at the properties of this igneous rock, and the various ways in which it is useful to us.
Basalt Stone Meaning Healing Properties The fiery spark of the Basalt Stone meaning comes from its origins, which started from molten lava that solidified quickly under intense heat and pressure. Also known as lava rock, the Basalt Stone is found in a range of colors from gray to black. Containing the intense power of volcanoes, use Basalt as ...
1) A hard, black, often glassy, volcanic rock. It was produced by the partial melting of the Earth''s mantle. 2) A stonelike, hard black unglazed pottery.
Basalt is the rock most typical of large igneous provinces. The largest occurrences of basalt are in the ocean floor that is almost completely made up by basalt. Above sea level basalt is common in hotspot islands and around volcanic arcs, specially those on thin crust.
Basalt Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity, and forms thin flows that can travel long distances. It is also found as intrusive dikes and sills.
