A theoretical protoplanet named "Theia" is thought to have collided with the forming Earth, and part of the material ejected into space by the collision accreted to form the Moon. As the Moon formed, the outer part of it is thought to have been molten, a "lunar magma ocean." Plagioclase feldspar crystallized in large amounts from this magma ocean and floated toward the surface. The cumulate rocks form much of the crust. The upper part of the crust probably averages about 88% plagiocl… Web2.7x104 Pa/m = 2.7x107 Pa/km = 27 MPa/km = 270 bars/km where MPa (=106 Pa) stands for megapascals.
