Tibetan and Indian lithospheres in the upper mantle beneath Tibet: Evidence from broadband surface‐wave dispersion

open access: yesGeochemistry, Geophysics, Geosystems, 2013
Broadband seismic experiments over the last two decades have produced dense data coverage across Tibet. Yet, the mechanism of the India‐Asia lithospheric convergence beneath it remains a puzzle, with even its basic features debated and with very ...

Horizontal mantle flow controls subduction dynamics [PDF]

open access: yes, 2017
It is generally accepted that subduction is driven by downgoing-plate negative buoyancy. Yet plate age –the main control on buoyancy– exhibits little correlation with most of the present-day subduction velocities and slab dips. “West”-directed subduction

Climate and Socio‐Sexual Environment Predict Interpopulation Variation in Chemical Signaling Glands in a Widespread Lizard

open access: yesIntegrative Zoology, EarlyView.
High phenotypic variation in femoral pore number across 55 populations of Podarcis muralis is best explained by a combination of positive allometry (size) and the local intensity of sexual selection (sexual dimorphism in body size, SSD) or local climatic conditions, notably temperature and vegetation density.

Active megadetachment beneath the western United States [PDF]

open access: yes, 2008
Geodetic data, interpreted in light of seismic imaging, seismicity, xenolith studies, and the late Quaternary geologic history of the northern Great Basin, suggest that a subcontinental-scale extensional detachment is localized near the Moho.

Tertiary-Quaternary subduction processes and related magmatism in the Alpine-Mediterranean region [PDF]

open access: yes, 2006
During Tertiary to Quaternary times, convergence between Eurasia and Africa resulted in a variety of collisional orogens and different styles of subduction in the Alpine-Mediterranean region.

An inventory of subglacial overdeepenings in southern Germany and Austria

open access: yesBoreas, EarlyView.
We present an inventory and morphometric characterization of >100 individual overdeepened basins in southern Germany and Austria compiled from heterogeneous sources. Arrangement and dimensions of overdeepenings are compared to those of their western Alpine counterparts, to catchment topographies and bedrock lithologies, and to modelled ice‐flow ...

The 2001 M_w 7.6 Bhuj earthquake, low fault friction, and the crustal support of plate driving forces in India [PDF]

open access: yes, 2011
We present a source model for the 2001 M_w 7.6 Bhuj earthquake of northwest India. The slip distribution suggests a high stress drop (~35 MPa) and, together with the depth distribution of aftershocks, that the entire crust is seismogenic. We suggest that

Post-collisional Tertiary–Quaternary mafic alkalic magmatism in the Carpathian–Pannonian region: a review [PDF]

open access: yes, 2004
Mafic alkalic volcanism was widespread in the Carpathian–Pannonian region (CPR) between 11 and 0.2 Ma. It followed the Miocene continental collision of the Alcapa and Tisia blocks with the European plate, as subduction-related calc-alkaline magmatism was

The Hudson Bay Lithospheric Experiment (HuBLE) : Insights into Precambrian Plate Tectonics and the Development of Mantle Keels [PDF]

open access: yes, 2015
The UK component of HuBLE was supported by Natural Environment Research Council (NERC) grant NE/F007337/1, with financial and logistical support from the Geological Survey of Canada, Canada–Nunavut Geoscience Office, SEIS-UK (the seismic node of NERC ...
