Caldera events in a rift depocentre: an example from the Jurassic Neuquen basin, Argentina 9 Jul 2013 | 08:58 pm
We analyse the volcanic stratigraphy of the Lower Jurassic synrift sequence of the Sañicó depocentre, which is a sub-basin of one of the most important hydrocarbon basins in South America, the Neuquén...
An increasing trend of diffuse CO2 emission from Teide volcano (Tenerife, Canary Islands): geochemical evidence of magma degassing episodes 9 Jul 2013 | 08:58 pm
Multiple soil CO2 efflux surveys have been undertaken at the summit cone of Teide volcano, Tenerife, from 1997 to 2011, to determine the total CO2 emissions from the summit cone and to evaluate the te...
Sub-aqueous sand extrusion dynamics 9 Jul 2013 | 08:58 pm
Extruded sandstone mounds and sandstone sheets are increasingly recognized in the geological record and seismic data, yet the underlying mechanisms that control these features, and determine whether d...
A U-Pb age for the Late Caledonian Sperrin Mountains minor intrusions suite in the north of Ireland: timing of slab break-off in the Grampian terrane ... 9 Jul 2013 | 08:58 pm
An intrusion of trachy-andesite, representative of a newly discovered suite of high-K–Ba–Sr, calc-alkaline minor intrusions (termed herein the Sperrin Mountains suite), hosted within the Grampian terr...
Constraints on the timing of Scandian deformation and the nature of a buried Grampian terrane under the Caledonides of northwestern Ireland 9 Jul 2013 | 08:58 pm
In the Caledonides of northwestern Ireland there is little evidence for the crystalline basement to the Dalradian Supergroup, though ascertaining its nature is a critical prerequisite for palaeogeogra...
The structural interpretation of domainal trace lineation: an example from the Mona Complex, Anglesey 9 Jul 2013 | 08:58 pm
Domainal trace lineation is defined by the intersection of two foliations, where at least one of these foliations is a composition banding formed by deformational processes (e.g. differentiated crenul...
Metamorphic zircon: tracking fluid pathways and the implications for the preservation of detrital zircon 9 Jul 2013 | 08:58 pm
Zircon in greenschist-facies Dalradian metasedimentary rocks of Scotland is characterized by two types: large detrital grains and small euhedral metamorphic grains. The former are concentrated in psam...
Lava-sediment interactions in an Old Red Sandstone basin, NE Scotland 9 Jul 2013 | 08:58 pm
The early Devonian, Old Red Sandstone succession at St. Cyrus, NE Scotland, includes the exceptional preservation of a lava field and its associated fluvial drainage system. The lava field developed t...
Analysis of structural trends of sub-sea-floor strata in the Isfjorden area of the West Spitsbergen Fold-and-Thrust Belt based on multichannel seismic... 9 Jul 2013 | 08:58 pm
A dense grid of 2D multichannel seismic data was used for the interpretation of sub-sea-floor structures in the area of Isfjorden in western Spitsbergen. West Spitsbergen underwent Eocene transpressio...
Quantifying rates of detachment faulting and erosion in the central Menderes Massif (western Turkey) by thermochronology and cosmogenic 10Be 9 Jul 2013 | 08:58 pm
Exhumation of rocks in extensional tectonic settings results from a combination of normal faulting and erosion but the relative contribution of these processes has rarely been quantified. Here we pres...
