basalt. One of the most abundant types of rock on Earth is basalt. It is a kind of igneous rock formed by the cooling of a certain type of molten lava. The lava cools and then hardens into a fine-grained crystalline rock ( see lava and magma ). The word basalt is believed to have come from an ancient Ethiopian word, basal, meaning “a rock

The mineral compositions of igneous rocks are usually described as being felsic, intermediate, mafic, or ultramafic (as examples, see Figure 4.7 and Figure 4.8). Felsic rocks are made of light-colored, low-density minerals such as quartz and feldspar. Mafic rocks are made of dark-colored, higher-density minerals such as olivine and pyroxene.

· Such reaction may result in: 1. Partial melting of the wall rock: For example, basalt magma with an inherent temperature of around 1,300 °C emplaced in the lower continental crust can partially melt the high-grade metamorphic wall rocks, whose solidus temperature is often around 1,000 °C at deeper levels.

4 · Basalt rock is mainly composed of pyroxene, olivine, and plagioclase and is the most common rock on the earth's surface.
