Deep lithospheric dynamics beneath the Sierra Nevada during the Mesozoic and Cenozoic as inferred from xenolith petrology [PDF]
, 2001 Peridotite xenoliths erupted in late Miocene basalts (~8 Ma) in the central Sierra Nevada sample a lithosphere that is vertically stratified in terms of age and thermal history.

Geofísica Internacional, 1973 La actual tendencia de definir la litósfera como una región de propiedades elásticas características, puede distorsionar un importante aspecto cualitativo de los procesos tectónicos en un planeta. Si se admite a escala de laboratorio que un mismo material puede comportarse casi clásticamente (como un sólido) o casi viscosamente (como un líquido) según ...

Remote Sensing in Ecology and Conservation, EarlyView.We compared local density measures of migratory birds collected using a mobile, vertically looking radar with reflectivity from a Next Generation Weather Radar (NEXRAD) station across varying distances and topographies. Broadly, mean nightly migration activity and within night migration activity between NEXRAD and the mobile radar were strongly ...

Geophysical Research Letters, 2021 Heat flow measurements are important for our understanding of planetary interior composition, structure, and evolution. In the absence of direct measurement, a first‐order estimate of a planet's interior heat flow can be made by modeling the lithosphere ...

The thermal state and interior structure of Mars [PDF]
, 2018 ©2018. American Geophysical UnionThe present‐day thermal state, interior structure, composition, and rheology of Mars can be constrained by comparing the results of thermal history calculations with geophysical, petrological, and geological observations.

Is There a Global Carbonate Layer in the Oceanic Mantle?
Geophysical Research Letters, 2021 Previous modeling of carbonate subduction by high‐pressure experimentation has allowed to propose scenarios for bulk carbon return to the mantle, but the detailed transfer mechanisms have seldom been studied.

An Evaluation of Proposed Mechanisms of Slab Flattening in Central Mexico [PDF]
, 2010 Central Mexico is the site of an enigmatic zone of flat subduction. The general geometry of the subducting slab has been known for some time and is characterized by a horizontal zone bounded on either side by two moderately dipping sections.

Seismotectonics of Mongolia and Baikal Rift Zone Controlled by Lithospheric Structures
Geophysical Research Letters, 2022 Active tectonics are developing in Mongolia and the Baikal rift zone, where large crustal earthquakes (Mw ≥ 6.0) occur frequently. To clarify the mechanism of these earthquakes, we determine a high‐resolution 3‐D P‐wave velocity model of the crust and ...

Evolving force balance during incipient subduction [PDF]
, 2004 Nearly half of all active subduction zones initiated during the Cenozoic. All subduction zones associated with active back arc extension have initiated since the Eocene, hinting that back arc extension may be intimately associated with an interval ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The concept of growing degree days (GDDs) is commonly used to predict phenological events in plants, assuming that plants develop proportionally to the accumulated temperature. Two species‐specific parameters, TBase and t0 (minimum temperature above which and start date
