Where can you find igneous rocks? How are metamorphic and igneous rocks alike and different? What provides clues about how igneous rocks were formed? How does magma turn into extrusive igneous rock? What are the two ways igneous rock is formed?
Hornblende (5-6) and Pyroxene minerals (5-6) are the main minerals in mafic basalts and gabbros. So, the minerals in igneous rocks have amoderately high hardnessand so igneous rocks themselves tend to be quite hard. They get even hard if they become a metamorphic rock....

During metamorphic transformation the garnet rims become more irregular on a first glance but on a closer view an eclogite-facies rim forms indicating equilibrium conditions with its adjacent phases on the µm to tens of µm scale. The thickness of this rim increased towards the shear zone ...
