Heterogeneity in the Lithosphere
2011Geologists and geophysicists have numerous ways to investigate and characterize heterogeneity in the earth. Geophysical characterization includes measurement of physical properties such as seismic velocities and density of rocks. Geological characterization includes mineralogical composition and grain size distribution that are both controlled by the ...

Intraplate alkaline lavas typically exhibit isotopic characteristics that require a source with long-term isolation from the convecting asthenosphere, such as in the sub-continental lithosphere mantle or a mantle boundary layer.

The Earth's lithosphere has a conductive (or advective) geothermal profile in contrast to the convecting asthenosphere with its adiabatic thermal gradient. The thickness of the sub-continental lithosphere (SCLM) varies with tectonothermal age: Archaean and Proterozoic SCLM is relatively cold, geochemically depleted and thick, while Phanerozoic SCLM is ...

Localized shear in the deep lithosphere beneath the San Andreas fault system
, 2014Seismic images of the base of the lithosphere across the San Andreas fault system (California, USA) yield new constraints on the distribution of deformation in the deep lithosphere beneath this strikeslip plate boundary. We show that conversions of shear

Models of Lithospheric Thinning
Annual Review of Earth and Planetary Sciences, 1987Lithospheric thinning denotes a gcodynamieal process that is associated with extensional tectonic phenomena. In plate tectonics the lithosphere is a layer of strength compared with the underlying asthenosphere. Its thick ness is commonly defined by the depth to a particular isothermal or by a fraction of the melting temperature of rocks.

Radioactivity of the Lithosphere
1962Zahlreiche Bestimmungen des Radioaktivitatsgehaltes der Lithosphare mittels physikalischer und chemischer Mesverfahren, bei denen etwa eine Messung auf 1017 g der zuganglichen Gesteinsphare kommen, liefern im Mittel folgende Werte: Haupttrager der Gesteinsaktivitat sind K40 (Haufigkeit 3 · l0-6g/g*), U238 (etwa 3 · 10-6 g/g) und Th232 (11–13·10-6 g/g).
