The Geodynamics series serves to showcase the diversity of research topics and/or methods in the geodynamics community.
In this week’s post, Fred Richards explains how ‘Dynamic Topography’ is used in the Geosciences, and discusses the knowns, unknowns, and the challenges ahead. Since shortly after its tumultuous formation billion years ago, Earth has been steadily. This book provides a summary of geodynamic results from Iceland that presently are found in a great number of scientific articles, but have not been collected before in a book.

Hole, James H. Natland. Article Download PDF. Article preview. Iceland's location astride the Mid-Atlantic Ridge, where the Eurasian and North American Plates are moving apart, is partly responsible for this intense volcanic activity, but an additional cause is necessary to explain why Iceland is a substantial island while the rest of the ridge mostly consists of seamounts, with peaks below sea level.

This book investigates how the emergence of the Arctic as a new geopolitical arena affects and reshapes the area known as the North Atlantic: Greenland, Iceland, the Faroe Islands and coastal Norway.
The relationship between the center of the former Danish empire and its subordinates have rested on (varying degrees of) asymmetric power.
A set of 95 fault plane solutions for earthquakes along the mid‐oceanic ridge system in the North Atlantic and Arctic has been compiled, several of which are reported here for the first time. All the solutions are single event solutions, and most of them are based on teleseismic, long period data.

Temperature estimates involving olivine addition to pillow-lava glasses are unreliable because host glasses formed along the liquid+olivine+plagioclase cotectic and not just the olivine liquidus.
Knowledge of the crustal structure of the Iceland-Faeroe Ridge is based on results from the North Atlantic Seismic Project of supplemented by earlier short refraction lines and reflection, gravity and magnetic surveys.
The main 5. 7 km/s upper crustal layer is locally overlain by lower velocity layers of variable thickness. Iceland (Icelandic: Ísland) is an island country at the confluence of the North Atlantic and Arctic oceans, east of Greenland and immediately south of the Arctic Circle, atop the constructive boundary of the northern Mid-Atlantic Ridge about km ( mi) from Scotland and 4, km (2, mi) from New York of the world's most sparsely populated countries, Iceland's boundaries are.
The geology of Iceland is unique and of particular interest to geologists. Iceland lies on the divergent boundary between the Eurasian plate and the North American also lies above a hotspot, the Iceland plume is believed to have caused the formation of Iceland itself, the island first appearing over the ocean surface about 16 to 18 million years ago.
1. Introduction. During the first half of the 20th century, petrology in Iceland revolved largely around three theoretical problems: (a) the paradox that despite being a part of the mid-Atlantic ridge, Iceland appeared to distinguish itself from it petrologically, (b) the relationship between the sub-alkalic and alkalic magma suites, and (c) the origin of the silicic rocks in Iceland, which.We present the results of a seismic survey performed around the Kolbeinsey Ridge, North Atlantic.
The seismic data were acquired along three profiles: on the ridge axis (Ll), 12 km off‐ridge (L2), an.
