The tectonic evolution of the southeastern Tibetan Plateau is key to understanding mechanism growth whole Plateau. Its imprint on lithospheric and asthenospheric mantle rock fabrics expected have a strong signature seismic anisotropy. In this study, we measure splitting delays fast polarization directions (FPD) with minimum-transverse-energy intensity methods using core-refracted phases (e.g., ...

Over the past several decades, shear-wave splitting (SWS) analyses have been increasingly utilized to delineate mantle structure and probe mantle dynamics. However, the reported splitting parameters (fast polarization orientations and splitting times) are frequently inconsistent among different studies, partially due to the different techniques used to estimate the splitting parameters. Here, w...

فاز SKS به‌صورت موج S از گوشته عبور می‌کند، در مرز هسته- گوشته به موج P تبدیل می‌شود، هسته خارجی را به‌صورت موج P طی می‌کند و سپس در برگشت به گوشته به موج S تبدیل می‌شود. اگر این فاز موج برشی از محیط ناهمسانگرد گوشته و پوسته زمین عبور کند، به دو مؤلفه موج برشی عمودبرهم، یکی سریع و دیگری کند قطبیده می‌شود. استفاده از فرایند جدایش موج برشی در محاسبه راستا و اندازه ناهمسانگردی مسیر انتشار موج، روش...

We present a novel method for reconstructing weak lensing mass or convergence maps as probe to study non-Gaussianities in the cosmic density field. While previous surveys have relied on flat-sky approximation, forthcoming Stage IV will cover such large areas with field of view (FOV) motivate reconstruction sphere. Here, we an improved Kaiser-Squires (KS+) inversion using HEALPix pixelisation sp...

Seismic anisotropy has been widely studied this last decade, particularly by measuring splitting of vertically propagating core shear waves. The main interest in this technique is to characterize upper mantle flow beneath seismic stations. On the other hand, the major restriction in this method is that a single station gives a single anisotropy measurement. Alternative methods have been develop...
