Our observations support the idea that rifting leading to continental break-up is a multi-phase process, and that serpentinization is the consequence rather than the reason for strain localization at non-volcanic margins. Apart from the more general implications for the tectonic evolution of ...
So much of the landscape that we travel through every day is the product of tectonic activity that we almost take for granted the immense forces that formed it! Try think twice next time you’re walking along the road, you have no idea what is going on beneath your feet… Share This Ar...
An international team of scientists, led by the University of Southampton, has found that the breakup of tectonic plates is the main driving force behind the generation and eruption of diamond-rich magmas from deep inside the Earth. This insight could significantly influence the trajectory of the ...
Subsequent Triassic rifting produced the Deep River and Dan River Basins, both of which have recently been considered for potential natural gas exploration. In total, North Carolina provides a remarkable record of a full Wilson's cycle worth of tectonic activity, including terrane accretions, a ...
The proposed hypotheses are based on empirical observations but are consistent with the generally accepted ideas that small intraplate earthquakes are ubiquitous and occur on preexisting faults in response to regional tectonic stress and that injected fluids can induce seismic slip by reducing normal ...
Although it guides the Late Miocene to Pliocene tectonic inversion of the Ser- rania, this fault still preserves its normal offset at basement level. This deep Urica fault was inherited from the Meso- zoic rifting and accounts for an abrupt thickening of the Mesozoic series toward the northeast...
Directional filtering, however, allows the northeast-trending structures associated with the rift to be subdued or removed from the maps, which facilitates the study of anomalies due to basement textures resultant from other tectonic events. It appears possible that the Mid-Continent rift could extend...
2) How does rifting relate to heat flow and magma penetration of the crust? 3) What leads to increased degree of crustal partial melting during rifting? 4) What are the subduction vs decompression signals in mafic magma? 5) What is the crustal architecture beneath the arc? 6) What is ...
Upper Cretaceous to Miocene rocks exposed on land record a complex tectonic history that may have also affected the adjacent Nicaraguan Rise, is now submerged and covered by up to 2.5 km of shallow carbonate banks that form a challenging barrier for both seismic imaging and drilling. This study...
We propose a review of the tectonic, magmatic and hydrothermal evolution of slow spreading ridges, focusing on concepts which we think are most relevant to discuss the rift to drift transition at magma-poor ocean鈥揷ontinent transitions (OCTs). Based on this review, we emphasize the importance...
