الصخور النارية. 20 أمثلة على الصخور النارية (بالصور)

While cooling, the magma evolves in composition because different minerals crystallize from the melt 1: crystallizes; 2: olivine and crystallize; 3: pyroxene and crystallize; 4: plagioclase crystallizes
If the approximate volume fractions of minerals in the rock are known, the rock name and silica content can be read off the diagram This is not an exact method, because the classification of igneous rocks also depends on other components than silica, yet in most cases it is a good first guess
