2- INTERMEDIATIC LAVA:

It is hotter than felsic lava. its temperature from 750* to 950*c. they occur low quantity of ALUMINIUM anaSILICON AND high quantity of MAGNESIUM and IRON.

3- MAFIC LAVA:

Its temperature excess of 950*c. in which high in IRON and MAGNESIUM and low in ALUMINIUM and SILICON.

4 - ULTRAMAFIC LAVA:

its temperature excess from 1600*c, highly in MAGNESIUM

5 - PILLOW LAVA:
