Crustal structure and magmatic evolution in the Pearl River Delta of the Cathaysia Block: New constraints from receiver function modeling

We utilized receiver functions to study the crustal structure beneath the Pearl River Delta in the southwestern part of the Cathaysia Block, which was characterized by widespread tectono-magmatism during the late Mesozoic. Combination of waveform modeling and H-k stacking was used to derive crustal thickness, Vp/Vs ratio and average P-wave velocity. The results show that the crustal thickness ranges from 26 km in the center of the Pearl River...
