Dome craters on Ganymede [PDF]

Voyager observations reveal impact craters on Ganymede that are characterized by the presence of broad, high albedo, topographic domes situated within a central pit. Fifty-seven craters with central domes were identified in images covering approx. 50% of

Numerical modelling of magma dynamics coupled to tectonic deformation of lithosphere and crust [PDF]

, 2017
Many unresolved questions in geodynamics revolve around the physical behaviour of the two-phase system of a silicate melt percolating through and interacting with a tectonically deforming host rock.

Interactions between mantle diapirs

Geophysical Research Letters, 1997
Experimental, theoretical, and numerical results are presented for the dynamics of interacting and deforming diapirs. The clustering of diapirs may occur as a result of the deformation induced by their mutual interactions. The time required for two diapirs in the mantle to merge can be small compared to their ascent time. The clustering of many diapirs,

Setting prospects for research and extraction of gas hydrates in the Black sea

Мінеральні ресурси України, 2016
The prospects of identification of gas hydrate deposits within the Black Sea are considered in the work. The areas are described that contain gene-fluids structures which are associated the methane-hydrated deposits.

Dynamic accumulation of a high-grade gas hydrate system: insights from the trial production gas hydrate reservoir in the Shenhu area, northern South China Sea

Frontiers in Marine Science
The ultimate enrichment level and quantity of gas hydrate resources are influenced by the dynamic process of accumulation and preservation. High-resolution 3-D seismic data, logging while drilling (LWD), pressured coring, and in situ testing were used to

An investigation into the controls of granite plutonism in the Sierra da Freita region, Northern Portugal [PDF]

, 2012
The Serra da Freita region of north central Portugal was chosen for study as it displays the complex relationships between regional structure, plutonism, regional and contact metamorphism typical of this part of Iberia.

Three‐dimensional attenuation model of Sierra Negra Volcano, Galápagos Archipelago

Geophysical Research Letters, 2016
The shallow magma system beneath Sierra Negra was imaged using attenuation tomographic methods. The t∗ spectral decay method for P wave phases was used to highlight regions of high Qp−1 which suggest the presence of magma melt.
