WebOct 1, 2024 · The crustal anisotropy mainly develops due to structural features such as faults, layering, flat mineral alignment, and regularly oriented cracks in the upper crust (e.g., Crampin, 1981; Mainprice et al., 2000; Boness and Zoback, 2006; Brownlee et al., 2024 ). WebIn recent years, P -to- S (or Ps) receiver functions (RFs) have been widely used to resolve complex media, such as dipping interfaces and layered anisotropy. Receiver functions represent P -to- S conversions at seismic discontinuities and can be expressed into a radial and a transverse component (Langston 1977; Vinnik 1977 ).
