The determination of the crustal structure is essential in geophysics, as it gives insight into the geohistory, tectonic environment, geohazard mitigation, etc. Here we present the latest advance on three-dimensional modeling representing the Tibetan Mohorovičić discontinuity (topography and ranges) and its deformation (fold), revealed by analyzing gravity data from GOCE mission. Our study show...
[1] In complex tectonics regions, seismological, geophysical, and geodynamic modeling require accurate definition of the Moho geometry. Various active and passive seismic experiments performed in the central Mediterranean region revealed local information on the Moho depth, in some cases used to produce interpolated maps. In this paper, we present a new and original map of the 3‐D Moho geometry...
We present a new approach to determine the 3-D topography and lateral continuity of seismic interfaces using 2-D-derived controlled-source seismic reflector data. The aim of the approach is to give the simplest possible structure consistent with all reflector data and error estimates. We define simplicity of seismic interfaces by the degree of interface continuity (i.e. shortest length of offse...
[1] Lateral variations of the crustal structure in southern California are determined from receiver function (RF) studies using data from the Southern California Seismic Network broadband stations and Los Angeles Regional Seismic Experiment surveys. The results include crustal thickness estimates at the stations themselves, and where possible, cross sections are drawn. The large-scale Moho dept...
A sensitivity study of stochastic crustal and Moho models on Moho refracted first arrivals is presented. The crustal model is a self-affine velocity structure superposed on a linear velocity gradient. The Moho is represented by a first-order discontinuity with a topography which is also self-affine. The sensitivity of both travel-time and wave-field is considered. We found that the full wave-fi...
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...
نمایش درمانی براساس مدل موهو به عنوان روشی جهت افزایش کفایت کودکان سندرم داون در زندگی روزمره و نیز انجام امور مربوطه به کار گرفته شد . ما از طریق مدل موهو سعی در تغییر و افزایش دیدگاه این کودکان نسبت به خود و محیط زندگی آنها و متناسب سازی خود واقعی با شرایط محیطی بودیم و در مرحله بعد با استفاده از نمایش درمانی شروع به درونی سازی و تکرار و آموزش آنها در محیط شبیه زندگی واقعی در صحنه نمایش بودیم.
Receiver functions are usually used to detect Ps converted waves and are especially useful to picture seismic discontinuities in the crust and upper mantle. In this study, the P receiver function technique beneath the west Iran is used to map out the lateral variation of the Moho boundary. The teleseismic data (Mb ≥5.5, epicentral distance between 30˚-95˚) recorded from 2004 to 2016 at 17 perma...
The upper lithospheric structure from the Pilbara Craton, across the Capricorn Orogen, to the northern Yilgarn Craton is determined from high-fidelity broadband seismic data. Three-component temporary stations were deployed in a line running southwards from Marble Bar, Western Australia, at approximately 118 E longitude. They were in position between July and October 2000. Receiver functions ar...
