Multiscale Analysis of Bouguer Gravity Anomalies: Unveiling the Deep Structure of Eastern Himalayan Syntaxis Faults

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Eastern Himalayan Syntaxis (EHS), which is located at the southeastern edge of the Qinghai–Xizang Plateau, is a key region for understanding mountain‐building and subduction processes. Bouguer gravity anomalies derived from the Earth Gravitational Model 2008 free‐air anomaly data following topographic corrections, were analyzed.

首都圈及其邻区的电性莫霍面探测

Dizhen xuebao
为了解首都圈地区电性莫霍面（eMoho）的分布情况，使用该地区电磁台网部分台站的长周期大地电磁数据，反演得到了首都圈地区的深部电性结构，该结果与前人使用地震、电磁、重力等资料得到的研究区地下结构具有较好的一致性，同时表明首都圈地区的地震学莫霍面附近也存在着电阻率变化特征。在此基础上，对反演所得的电阻率曲线求取一阶导数，以此来刻画测点下方电性莫霍面的深度位置，继而建立三类地层模型验证了该方法的可行性，并对实测资料反演结果求取一阶导数，结果凸显了电性莫霍面的分布，所得电性莫霍面与地震 ...

The lithospheric mantle and lower crust-mantle relationships under Scotland: a xenolithic perspective [PDF]

, 2011
In the British Isles the majority of volcanic rocks containing upper mantle and lower crustal xenoliths occur in Scotland. Most of the occurrences are of Carboniferous–Permian age.

On the Construction of Moho Reflected Shear Wave Phases From Ambient Noise

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Shear waves reflected from the Moho (SmS) are frequently identified in ambient noise cross‐correlation functions. Despite their consistent appearance across various arrays and studies, the physical origin and generation mechanisms of these SmS phases remain poorly understood.

Late Triassic Hydroclimatic Changes in Central China Linked to Evolving Mountain Topography

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract During the Late Triassic, tropical Pangea drifted northward into subtropical latitudes and became progressively drier. In contrast, South China, despite experiencing a similar latitudinal shift, transitioned from an arid to humid climate. Based on the sedimentary record of the Zigui Basin, this study constrains the arid to humid climatic shift

U and Th content in the Central Apennines continental crust: a contribution to the determination of the geo-neutrinos flux at LNGS

, 2011
The regional contribution to the geo-neutrino signal at Gran Sasso National Laboratory (LNGS) was determined based on a detailed geological, geochemical and geophysical study of the region.

Hunting for oceanic island Moho [PDF]

Geophysical Journal International, 2005
SUMMARY The structure of the oceanic crust conforms in general to a very simple model. However, fine-scale variations of this structure in anomalous regions (such as beneath oceanic islands) remain poorly resolved. Here we examine teleseismic receiver functions (RFs) computed at four permanent broadband seismic stations on islands in the Pacific region.

Migration of Multimodal Deep Crustal Earthquake Swarm Beneath the Abu Volcano Group, Japan

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes in the lower crust, where high pressures and temperatures favor ductile deformation, are rare but occasionally occur beneath active volcanic centers, providing insights into deep magmatic processes. We analyze a deep crustal earthquake swarm (February–August 2025) of over 5,000 events beneath the Abu Volcano Group, Japan.
