Shallow bias in Neogene palaeomagnetic directions from the Guide Basin, NE Tibet, caused by inclination error
(Blackwell Science Ltd, 2005-12)
Too-shallow inclinations have frequently been observed in Cenozoic sedimentary strata in central Asia, and new palaeomagnetic results obtained by us from the Guide Basin in NE Tibet are no exception. We use a statistical ...
Comparison of garnet-biotite, calcite-graphite, and calcite-dolomite thermometry in the Grenville Orogen; Ontario, Canada
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-02)
The Elzevir Terrane of the Grenville Orogen in southern Ontario contains metapelites and abundant graphitic marbles that were regionally metamorphosed from the upper greenschist to upper amphibolite facies. Comparative ...
Chlorite control of correlations between strain and anisotropy of magnetic susceptibility
(Elsevier, 1990)
Anisotropy of magnetic susceptibility (AMS) has in the past been used as an indicator of finite strain; mathematical relationships between the measured AMS ellipsoid and the finite strain ellipsoid in slates are numerous. ...
Magmatic and hydrothermal inclusions in carbonatite of the Magnet Cove Complex, Arkansas
(Springer-Verlag, 1977-08)
The carbonatite at Magnet Cove, Arkansas, USA contains a great variety and abundance of magmatic and hydrothermal inclusions that provide an informative, though fragmentary, record of the original carbonatite melt and of ...
Global prediction of abyssal hill roughness statistics for use in ocean models from digital maps of paleo-spreading rate, paleo-ridge orientation, and sediment thickness
(Elsevier, 2010)
Abyssal hills are the dominant small-scale roughness fabric over much of the ocean floor. Created at midocean
ridges by combined volcanic and tectonic processes, they are rafted away by plate spreading and
modified through ...
Pyrometamorphism and partial melting of shales during combustion metamorphism: mineralogical, textural, and chemical effects
(Springer-Verlag, 1992-12)
Eocene shales metamorphosed by a naturally ignited coal seam in the Powder River Basin, Wyoming record a continuum of mineralogic and textural changes from relatively unaltered shale to melt developed during pyrometamorphism. ...
