Geochemists solve mystery Earth vanishing crust
2020/7/10
Earth's crust is the solid, outermost layer of our planet. Much of what happens below that layer remains a mystery, including the fate of sections of crust that vanish back into the Earth.Now, a team ...
Scientists determine early Earth was a ‘water world’ by studying exposed ocean crust（图）
Scientists early Earth water world’ exposed ocean crust
2020/3/13
The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say, after analyzing oxygen isotope data from ancient ocean crust now exposed on land in Australia. The findi...

New Details Temperature Mobility Earth’s Lower Crust Rocky Mountains
2018/2/1
Everything on the surface of the Earth rests on massive tectonic plates that resemble a jelly sandwich, with two rigid pieces — the upper crust and the upper mantle — enclosing a gooey middle layer of...
Resistivity and heterogeneity of Earth crust in an active tectonic region,Southern Tuscany (Italy)
crustal exploration magnetotellurics geothermal areas
2015/9/14
Southern Tuscany, belonging to the inner zone of the Northern Apennines, Italy, is an ideal laboratory for observing the physical features of the lithosphere and their evolution in tectonically active...
Cooling of a channeled lava flow with non-Newtonian rheology: crust formation and surface radiance
Rheology Magmas Thermodynamics Lava flow Effusion rate
2015/8/27
We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bend...

Positive geothermal anomalies oceanic crust Cretaceous age offshore Kamchatka
2014/12/31
Heat flow measurements were carried out in 2009 offshore Kamchatka during the German-Russian joint-expedition KALMAR. An area with elevated heat flow in oceanic crust of Cretaceous age – detected ~30 ...
The crust and uppermost mantle structure of Southern Peru from ambient noise and earthquake surface wave analysis
Central Andes flat subduction surface wave tomography
2014/4/10
Southern Peru is located in the northern Central Andes, which is the highest plateau along an active subduction zone. In this region, the Nazca slab changes from normal to flat subduction, with the as...
Evolution history of the crust underlying Cerro Pampa, Argentine Patagonia: Constraint from LA-ICPMS U–Pb ages for exotic zircons in the Mid-Miocene adakite

2017/4/11
This paper newly reports results of LA-ICPMS U–Pb dating for 282 zircon crystals separated from a Middle Miocene
adakite in Cerro Pampa, southern Argentine Patagonia. With the exception of one spot a...

Postglacial Deformation of the Fennoscandian Crust
crustal deformation geodynamics glacial isostasy land uplift postglacial rebound stress phenomenon
2009/6/10
Generally speaking, crustal deformation has three components, one vertical and two horizontal.
This must hold true also for the Fennoscandian Shield. One of them, the vertical component, has been und...
Structure of the Earth's Crust in Fennoscandia as Revealed from Refraction and Wide-Angle Reflection Studies
crustal structure Fennoscandia refraction wide-angle reflection Moho-map
2009/6/10
The crustal structure in Fennoscandia has been intensively studied by seismic methods over the
last one and half decade. The features and differences of the crustal structure are discussed by reviewi...
Deep Structure of the Earth's Crust Along the SVEKA Profile and its Extention to the North-East
lithosphere Earth’s crust gravity modeling density
2009/6/10
A new integrated seismic and density model along the SVEKA profile in Finland is presented. The model has been obtained as a result of application of non-traditional approach to gravity data inversion...
