Q2- A rock has been erystallized form magma then it is changed into a metamorphic rock and finally become a sedimentary rock as sandstone with mineral contents of quartz ( 85%), potassium feldspar (10%) and mica. 1- What is the name of igneous rock which contents these minerals? what is the type of this rock regarding silica content ? 2- What is the type of magma which produces this igneous rock ? what is the type of this rock regarding the environment of formation? 3- If we assume () that this igneous rock is formed from lava, what are the type of lava, viscosity and the volcanic eruptions produce this igneous rock?
