Gabbro and Basalt have the same chemical composition, and often the same or similar mineral composition The difference is the TEXTURE Basalt cooled quickly and is therefore fine grained to even glassy, with or without phenocrysts (individual large crystals)...
The chemical composition of basalt is close to gabbro which is its analogue in depth Almost completely crystalline basalts are called dolerit Basalts which are greatly decomposed and altered by secondary processes are known as diabases and basalt-porphyry...
Basalt is not a mineral, because is can not be expressed in a definite chemical equation, nor does it have a definite crystal structure Basalt is a hard, black volcanic rock with less than about 52 weight percent silica (SiO2) Common minerals in basalt include olivine, pyroxene, and plagioclase...
The geometrical and mechanical properties and chemical composition of different basalt and glass fibers have been investigated Tensile tests were performed on short basalt fiber made by melt blowing, glass fiber and three different types of continuous basalt fibers made by spinneret method...
Chemical Composition of Magmas The chemical composition of magma can vary depending on the rock that initially melts (the source rock), and process that occur during partial melting and transport Initial Composition of Magma The initial composition of the magma is dictated by the composition of the source rock and the degree of partial melting...
What do the terms mafic and felsic mean? These are both made up words used to indicate the chemical composition of silicate minerals, magmas, and igneous rocks Mafic is used for silicate minerals, magmas, and rocks which are relatively high in the heavier elements...
