Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography
Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.

Neotectonics of the ocean-continent transition zone in the Côte d'Ivoire region (West Africa)
Structural and geophysical indicators of neotectonics in the area of the continental margin of Côte d'Ivoire are represented in three interacting zones: oceanic, continental and transitional.

Glacio and hydro-isostasy in the Mediterranean Sea: Clarks zones and role of remote ice sheets
Solving the sea-level equation for a spherically symmetric Earth we study the relative sea-level curves in the Mediterranean Sea in terms of Clarks zones and we explore their sensitivity to the time-history of Late-Pleistocene ice aggregates ...

Properties of the lithosphere and asthenosphere deduced from geoid observations [PDF]
Data from the GEOS-3 and SEASAT Satellites provided a very accurate geoid map over the oceans. Broad bathymetric features in the oceans such as oceanic swells and plateaus are fully compensated.

Mantle convection plays a fundamental role in driving evolution of oceanic and continental lithosphere. In turn it impacts a broad suite of processes operating at or close to Earth's surface including landscape evolution, glacio‐eustasy, magmatism, and ...

(独)海洋研究開発機構(JAMSTEC)では、2002年から伊豆・小笠原・マリアナ島弧において、大陸地殻の生成過程を明らかにすることを目的に構造調査を進め、現在の島弧地殻のボリュームより多くの玄武岩マグマが必要で島弧地殻を生成する過程でマフィックな島弧地殻の一部をマントル内に戻していること(Takahashi et al., 2007, 2008; Tatsumi et al., 2008)、火山フロントと背弧側の地殻の厚さ分布には相関があり過去のリフティングが検出されたこと(Kodaira et al.

Early Cenozoic denudation of central west Britain in response to transient and permanent uplift above a mantle plume [PDF]
Upwelling mantle plumes beneath continental crust are predicted to produce difficult to quantify, modest uplift and denudation. The contribution of permanent and transient components to the uplift is also difficult to distinguish.

Depth-dependent density change within the continental upper mantle
The empirical model of the depth-dependent density change within the upper continental mantle is derived in this study. The density of the upper(most) mantle underlying the continental crust is obtained from the estimated values of the crust–mantle (Moho)

Investigation of lunar crustal structure and isostasy [PDF]
The lunar mascon basins have strongly free air gravity anomalies, generally exceeding 100 milligals at an elevation of 100 km. The source of the anomalies is a combination of mantle uplift beneath the impact basins and subsequent infilling by high ...
