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...
Experiments call origin of Earth's iron into question
Experiments call origin Earth's iron
2017/3/14
New research from The University of Texas at Austin reveals that the Earth’s unique iron composition isn’t linked to the formation of the planet’s core, calling into question a prevailing theory about...
Geologic imaging technique measures strength of Earth’s outer shell
Geologic imaging technique measures strength Earth’s outer shell
2016/10/10
An advanced imaging technique used to map Earth’s outer shell also can provide a measure of strength, finding weak spots and magma upwellings that could point to volcanic or earthquake activity, accor...
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...
Background electromagnetic noise characterization: the role of external and internal Earth sources
Radio noise characterization Ionosphere-magnetosphere Background EM noise Crustal/lithospheric EM sources
2015/8/14
The Earth is surrounded by the ionosphere and magnetosphere that can roughly be seen schematically as two concentric shells. These two composed and inhomogeneous structured shells around the Earth sel...
This paper shows how modern ideas of scaling can be used to model topography with various morphologies and also to accurately characterize topography over wide ranges of scales. Our argument is divide...

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...
