Assessing the role of compaction in the formation of adcumulates: a microstructural perspective

MB Holness, Z Vukmanovic, E Mariani - Journal of Petrology, 2017‏ - academic.oup.com
The formation of adcumulates necessitates the continued growth of primocrysts down to low
porosities. Gravitationally driven viscous compaction at the base of a crystal mushy layer on …

Axial‐type olivine crystallographic preferred orientations: The effect of strain geometry on mantle texture

Rock mechanics constraints on mid-crustal low-viscosity flow beneath Tibet

EH Rutter, J Mecklenburgh, KH Brodie - 2011‏ - pubs.geoscienceworld.org
It has been inferred from various types of geophysical data that the Tibetan middle and
upper crust is detached from the underlying lower crust and mantle by a weak, mid-crustal …

Rheology of Mg2GeO4 olivine and spinel harzburgite: Implications for Earth's mantle transition zone

F Shi, J Zhang, G **a, Z **… - Geophysical Research …, 2015‏ - Wiley Online Library
Geophysical modeling requires an upper mantle low‐viscosity zone (LVZ); recent results
suggest that the LVZ could be within the mantle transition zone (MTZ) or above it, depending …

Localization in rate-dependent shearing deformation, with application to torsion testing

MS Paterson - Tectonophysics, 2007‏ - Elsevier
The localization of plastic deformation in rock is of particular interest in geology in
connection with the formation of “ductile” shear zones. It is commonly conjectured that strain …
