Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina [PDF]
The North Patagonian Massif is an Argentinean plateau that has an average height of 1200 m and stands from 500 to 700 m above the neighboring areas. During Paleogene, it suffered a sudden uplift of more than 1200 m without noticeable internal deformation;

DEEP STRUCTURE OF THE ALTAI MOUNTAINS AND MODERN GRAVITY FIELD MODELS
The results of the ground-based absolute gravity and space geodetic measurements for the Altai Mountains were considered in combination with EIGEN-6C4 Global Geopotential Model (ETOPO1 Global Relief Model) generated from the satellite data.

The effective elastic thickness of the India Plate from receiver function imaging, gravity anomalies and thermomechanical modelling [PDF]
The range and the meaning of the effective elastic thickness (EET) in continental areas have been subject to controversy over the last two decades. Here we take advantage of the new data set from the Hi-CLIMB seismological experiment to re-estimate the ...

A recovered Moho model by integrated inversion of gravity and seismic depths in Iran
This research aims to define the depth of Moho in Iran by collocation method using gravimetric data with seismic information. The definition of the Moho in the Iranian region is of considerable importance due to the geological complexity of the area also

基于多台站的接收函数和重力联合反演确定莫霍面起伏和地壳平均波速比
地壳厚度和波速比是研究地壳结构和组分的两个重要参数,可为区域构造研究提供重要约束。接收函数被广泛地用于确定地壳厚度和波速比,例如H-κ方法或H-κ-c方法,但是该方法只能确定台站下方的地壳厚度和速度比,当地震台站分布稀疏时,很难约束台站间的横向不均匀性。另一方面,重力数据也可用于莫霍面的起伏变化研究,它在横向上覆盖很好,有较高的分辨率,但在纵向上分辨率相对较低。为此,本研究提出了一种联合反演算法求解莫霍面深度和地壳波速比参数 ...

Fully nonlinear inversion of fundamental mode surface waves for a global crustal model [PDF]
We use neural networks to find 1-dimensional marginal probability density functions (pdfs) of global crustal parameters. The information content of the full posterior and prior pdfs can quantify the extent to which a parameter is constrained by the data.

Moho depth variations in North West Iran estimated from the Moho reflected phases
Abstract In this study, we picked Moho reflected phases and used them to estimate the spatial variation of the Moho depth in northwestern Iran. Moho reflected phases are secondary phases which can be observed at the distance range between 60 and 200 km.
