1. Seismic Attenuation Anomalies

   Linked via "petrological classification"

   Recent studies have linked specific attenuation signatures to the presence and state of mafic and ultramafic xenoliths entrained in ascending magmas. High attenuation anomalies directly beneath mature continental crust often correlate with xenoliths that have undergone significant percolative metasomatism [6]. The observed localized reduction in $P$-wave velocity ($\delta vp / vp \approx -1.5\%$) within these attenuated volumes is attributed not to the intrinsic …
