英文摘要The Neo-Tethys subduction and subsequent Arabia-Eurasia continental collision invoked widespread Cenozoic tectono-magmatism throughout the Iranian Plateau. We herein develop a new method to image the shallow crustal S-wave velocity (V-s) structure by joint inversion of multifrequency waveforms and horizontal-to-vertical ratios around the direct P phase in P-wave receiver functions. Synthetic tests demonstrate the validity of our method in constraining the absolute V-s values beneath single stations down to similar to 12-km depth. By applying this method to a seismic array of 63 stations with an average spacing of similar to 10 km along the main profile, we construct a detailed shallow crustal V-s model across the northwestern Iranian Plateau. The model is characterized by distinct high- and low-velocity anomalies beneath the Iranian hinterland and the Zagros foreland fold-and-thrust belt, respectively. In combination with geological observations and laboratory data, the imaged high-velocity anomalies (with V-s of 3.2-3.9 km/s) may denote arc to intraplate magmatism beneath Central Iran and Alborz to the north, whereas the low-velocity anomalies (with V-s of similar to 1.65 km/s) probably represent the marl/shale layers in Late Cretaceous and Paleocene beneath Zagros. The magmatic rocks at the Iranian hinterland exhibit strong variations in absolute V-s, reflecting different bulk compositions with more mafic inland. The shale/marl layers could have acted as decollements to accommodate crustal deformation. Our observations underline both the key role of lithology-controlled layering in sedimentary deformation at the Zagros fold-and-thrust belt and the change in compositions and forming-environments of magmatic rocks at the Iranian hinterland.
