between arc basalt composition and Moho depth Quantifying crustal thickness variations in evolving orogens : Correlation
A compilation of geochemical data from >50 active volcanoes where seismically defi ned Moho depth measurements are available, representing most volcanic arcs around the world, indicates a relation exists between crustal thickness (Moho depth) and the trace element composition of basalts. The best correlation exists for maximum light/heavy rare earth element (REE) ratios, and we use maximum Ce/Y...
متن کاملMoho depth variation in southern California from teleseismic receiver functions
The number of broa.dband three-component seismic stations in southern California. has more tb an tripled recently. In th is study we use the teleseismic receiver function technique to determine the crustal thicknesses and Vp / Vs ratios for th ese stations and map out t he lateral variation of Moho dept h under southern California. It is shown t hat a. receiver function can provide a very good ...
متن کاملMoho depth and crustal thinning in the Marmara Sea region from gravity data inversion
The free-air gravity in the Marmara Sea reveals that the low density of sedimentary basins is partly compensated in the lower crust. We compiled geophysical upper crust studies to determine the sediment basin geometries in and around the Marmara Sea and corrected the gravity signal from this upper crust geology with the Parker method. Then, assuming long wavelength anomalies in the residual gra...
متن کاملJoint inversion for crustal and Pn velocities and Moho depth in Eastern Margin of the Tibetan Plateau
a r t i c l e i n f o A classical problem in seismic tomography is the trade-off between a discontinuity location and the velocity of the medium. For that reason, crustal tomography and Pn tomography are typically done separately by isolating first-arriving Pg and Pn waves. Although this avoids the contamination of secondary arrivals because of the existence of the Moho, lots of good data are d...
متن کاملCrustal and uppermost mantle structure in southern Africa revealed from ambient noise and teleseismic tomography
S U M M A R Y Rayleigh wave phase velocity maps in southern Africa are obtained at periods from 6 to 40 s using seismic ambient noise tomography applied to data from the Southern Africa Seismic Experiment (SASE) deployed between 1997 and 1999. These phase velocity maps are combined with those from 45 to 143 s period which were determined previously using a two-planewave method by Li & Burke. In...
