Types of Convergent Boundaries Oceanic-Continental Continental-Continental Oceanic-Oceanic
Igneous Rocks and Plate Tectonics • Over geologic time these processes first created oceanic crust from ultramafic mantle rocks. In turn, the mafic oceanic crust created felsic continental crust from partial melting of hydrated basalt. Continental crust is less than 1% of earth’s mass, so there isn’t a lot of felsic material in the earth. Most has risen to the crust.
