...Alexandre M. Tartakovsky; Paul Meakin Abstract Smoothed particle hydrodynamics (SPH) models were used to simulate unsaturated flow in fractures with complex geometries. The SPH is a fully Lagrangian particle-based method that allows the dynamics of interfaces separating fluids to be modeled without...

.... The form of the complex as a whole shows that this cycle occurred repeatedly, but with the location of magma generation migrating progressively westwards, resulting in a chain of rhyolitic cauldrons, into which subvolcanic granites and syenites have been emplaced.

... synthesize field- and seismic reflection–based observations and highlight that extensive lateral magma transport (as much as 4100 km) may occur within mafic sill complexes. Most of these mafic sill complexes occur in sedimentary basins (e.g., the Karoo Basin, South Africa), although some intrude crystalline...

...DAVID J. BROWN; EOGHAN P. HOLOHAN; BRIAN R. BELL Abstract Research on the British Paleocene Igneous Province (BPIP) has historically focused on the emplacement, chemistry and chronology of its elaborate central intrusive complexes and lava fields. However, the BPIP has also been dramatically shaped...

... the internal part of the mountain belt ( Balanyá & García-Dueñas 1987 ). The third major tectonic unit is known as the Alborán domain or Internal Zones ( Balanyá & García-Dueñas 1987 ), and mainly comprises three nappe complexes of variable metamorphic grade, which are, from bottom to top, the Nevado...

... Betics that comprise predominantly sheared, folded and faulted schists, phyllites, quartzites and carbonates. Steep and complex terrain, adverse structure, highly disturbed rock masses, seasonally intense rainfall and coastal erosion create a challenging environment for infrastructure and urban...

... Scotland, and examined how magma flow in sheet intrusions may vary along and perpendicular to the magma flow axis. The sheets form part of the Ardnamurchan Central Complex, which represents the deeply eroded roots of an ∼58-m.y.-old volcano. Our results suggest that the inclined sheets were emplaced via...

... zonation based exclusively on single-station microtremor measurements is not a reliable alternative when the local geology is complex and site effects are not the result of a single-impedance contrast. For this reason, we applied two independent analysis techniques to array measurements of microtremors...

The results confirm that fractionation of phenocrysts found in the lavas does not reproduce trace element variations, in particular...
