Fluids of the lower crust: deep is different

CE Manning - Annual Review of Earth and Planetary Sciences, 2018‏ - annualreviews.org
Deep fluids are important for the evolution and properties of the lower continental and arc
crust in tectonically active settings. They comprise four components: H2O, nonpolar gases …

The role of water in the evolution of the continental crust

BWD Yardley - Journal of the Geological Society, 2009‏ - lyellcollection.org
Aqueous fluids have a profound influence on the evolution of the crust, both as agents of
chemical mass transfer and mineral reactions, and through modifying its rheology. This …

Fault stress states, pore pressure distributions, and the weakness of the San Andreas fault

JR Rice - International geophysics, 1992‏ - Elsevier
Abstract The San Andreas Fault (SAF) is weak in an absolute sense, in that it moves under
shear stresses far smaller than implied by the most obvious reading of laboratory friction …

Detection of widespread fluids in the Tibetan crust by magnetotelluric studies

W Wei, M Unsworth, A Jones, J Booker, H Tan… - Science, 2001‏ - science.org
Magnetotelluric exploration has shown that the middle and lower crust is anomalously
conductive across most of the north-to-south width of the Tibetan plateau. The integrated …

Physical model of source region of subduction zone volcanics

JH Davies, DJ Stevenson - Journal of Geophysical Research …, 1992‏ - Wiley Online Library
The thermal structure of a generic subduction zone is investigated to elucidate the source
region of subduction zone volcanics. The steady state thermal field is evaluated for a model …

[PDF][PDF] The seismic velocity structure of the deep continental crust

WS Holbrook, WD Mooney… - Continental lower crust, 1992‏ - researchgate.net
Despite its importance to the study of continental crustal evolution, the composition of the
lower part of the Earth's crust remains poorly known, largely because of the difficulty of …

α/β phase transition in quartz monitored using acoustic emissions

PWJ Glover, P Baud, M Darot… - Geophysical Journal …, 1995‏ - academic.oup.com
It is usually suggested that thermal cracking in a quartz-bearing rock results from the
anomalously high volumetric expansion coefficients of quartz (eg Simmons & Cooper 1978) …

The petrologic case for a dry lower crust

BWD Yardley, JW Valley - Journal of Geophysical Research …, 1997‏ - Wiley Online Library
Fluid pressure in the crust may be controlled by different mechanisms according to depth,
temperature, and the mineralogy of the host rocks. Where rocks are fluid‐saturated, fluid …

Crustal flow in Tibet: geophysical evidence for the physical state of Tibetan lithosphere, and inferred patterns of active flow

SL Klemperer - 2006‏ - pubs.geoscienceworld.org
Many seismic and magnetotelluric experiments within Tibet provide proxies for lithospheric
temperature and lithology, and hence rheology. Most data have been collected between c …

Rheology of the lithosphere in space and time

G Ranalli - Geological Society, London, Special Publications, 1997‏ - lyellcollection.org
The rheology of the lithosphere is a factor of primary importance in the kinematics and
dynamics of mountain belts. This paper attempts to clarify the role of rheology in orogenesis …
