Crystal preferred orientation
WebSep 21, 2024 · This alignment is referred to as lattice preferred orientation or crystallographic preferred orientation (CPO). When the shear strain causes strong alignment over a large enough volume, the CPO creates an observable anisotropy in seismic observations made at stations on the Earth's surface. WebPreferred orientation arises when there is a stronger tendency for the crystallites in a powder or a texture to be oriented more one way, or one set of ways, than all others. …
