Grain size data for plagioclase in BIPIP basaltic dykes. This data was collected as part of a study of the lateral variation in grain size in dykes that propagated laterally for significant distances (up to 300km) through the shallow crust, with a range of bodies sampled both close to their magmatic source on the NW coast of Scotland, and far from ...
On the volcanic ocean island Tenerife in the Canary archipelago, several giant flank collapses haveoccurred over the last one million years. The link between the lateral collapses and the resultingvolcanism in the rift zones is not fully understood and was investigated within the framework of thisproject. A field survey along the north eastern rift...
A case study involving the assessment and re-design of an existing dyke, founded on a layered soil, has compared deterministic analysis based on 5-percentile property values and a reliability-based random finite element analysis consistent with the requirements of Eurocode 7. The results show that a consideration of the spatial nature of soil varia...

Numerous Riphean mafic dykes cross-cut Precambrian clastics and carbonates on the western slope of the Southern Urals. An andesite dyke with an isotope age of 71 ± 1 Ma (U–Pb SHRIMP II on zircons) encountered among metamorphic rocks of the Taratashskii complex (Archean–Early Proterozoic) at the northern terminus of the Bashkirian meganticlinorium a...
The NW sector of Mauritania represents the Archean province of the Reguibat Ridge. It is mainlycomposed of the typical Archaean cratonic association of granitoid gneisses, greenstones belts andgranites. The greenstone belts contain high mineral potential, mainly gold. This is particularly thecase of the Chami Greenstone Belt, which hosts the large ...

Volcanic eruptions pose a threat to lives and property when volcano flanks and surroundings are densely populated. The local impact of an eruption depends firstly on its location, whether it occurs near a volcano summit, or down on the flanks. Then forecasting, with a defined accuracy, the location of a potential, imminent eruption would significan...
Recent studies show an increase in the population of beavers, nutria and other rodents in vast regions of central Europe over the last 15 years. Unfortunately, this caused in many instances considerable damage on large rivers along dykes and earthworks in the floodplain areas, leading to an increased risk of bank failures. However, most of these ma...

Intracratonic South Rewa Gondwana Basin occupies the northern part of NW–SE trending Son–Mahanadi rift basin of India. The new gravity data acquired over the northern part of the basin depicts WNW–ESE and ENE–WSW anomaly trends in the southern and northern part of the study area respectively. 3D inversion of residual gravity anomalies has brought o...

This paper presents geochronological data for the volcanic dykes located in the northern Považský Inovec Mts. The dykes are up to 5 m thick and tens to hundreds of metres long. They comprise variously inclined and oriented lenses, composed of strongly altered grey-green alkali basalts. Their age was variously interpreted and discussed in the past. ...
Het buitendijkse dijktracé langsheen de Sint Pieterspolder en Nieuw Olzendepolder heeft een belangrijke functie als hoogwatervluchtplaats voor een aantal soorten steltlopers en eendachtigen. Met name Scholekster, Wulp, Tureluur, en in mindere mate Steenloper gebruiken de buitendijkse zijde van de zeedijk langs de Nieuw Olzendepolder en de St. Piete...
