The word basalt comes from a Latin word meaning very hard stone. Though basalt is typically a dark, black rock, weathering can lead to a yellowbrown color. Basalt may also be found in various shades because of geochemical processes. A lightcolor basalt is rare, but can be found due to a high concentration of plagioclase and weathering.
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 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 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.
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.

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.
