Basic Types of Anisotropy • Transverse Isotropy • Azimuthal anisotropy • Composite (cracks)
Causes of Anisotropy • Lattice Preferred Orientation (LPO) • Alignment of mineral grains • Shape Preferred Orientation (SPO) • Alignment of heterogenieties • Cracks • Melt lenses
Azimuthal Anisotropy “Azimuthal” anisotropy: like transverse isotropy on its side
D″ Anisotropy • Lattice-Preferred Orientation (LPO)? • Shape-Preferred Orientation (SPO)? • Result of a Chemical Boundary Layer? • Related to Slabs? McNamara, van Keken, and Karato [2002]
