What is a Rifted Margin? From the Early Models to Modern Views and Future ChallengesRifted margins are major geological objects that mark the transition between continents and oceans, the two first-order types o
Distance refers to the length between two places or points. There is also two-term displacement, which looks similar but is not the same. Displacement is the shortest distance between two points while distance refers to the length covered to reach from ...
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 hard, solid, rocky slabs found in the outermost layer of the Earth are known as tectonic plates, which move continuously, reshaping the planet's surface. Their presence explains the historical and outgoing movement of the Earth's surface has resulted in the creation of the...
Krakatoa lies along the convergence ofthe Indian-Australian and Eurasian tectonic plates, a zone of high volcanic and seismic activity. What type of plate boundary is Krakatoa on? The plates involved in Krakatau are the Eurasian plate and the Indonesian-Australian plate. At thisconvergent plate bou...
The trouble here is that with a larger planet, gravity is larger so mountains are unable to grow so high. (the strength of the crust is a genuine limit to the height that mountains can grow - only where immense tectonic forces squeeze entire continents together can we build mountain chains...
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...
is an example of a tectonic estuary. Such estuaries form due to tectonic activity, i.e., shifting together and rifting apart of the Earth’s crust. Moreover, when a barrier island separates an estuary from the sea, we call it a bar-built estuary. Fjord estuaries are a form of estuaries...
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...
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 ...
