• PALAEONTOLOGICAL EVIDENCE BEARING ON GLOBAL ORDOVICIAN-SILURIAN CONTINENTAL RECONSTRUCTIONS 

  Fortey R.A.; Cocks L.R.M. (2003)

  The discreteness or otherwise of major Ordovician and Silurian terranes can be recognised by the shallow-water benthic faunas which lived upon them. Their borders are often indicated by the disposition of progressively ...
• DENSITY OF THE CONTINENTAL ROOTS: COMPOSITIONAL AND THERMAL CONTRIBUTIONS 

  Kaban M.K.; Schwintzer P.; Artemieva I.M.; Mooney W.D. (2003)

  The origin and evolution of cratonic roots has been debated for many years. Precambrian cratons are underlain by cold lithospheric roots that are chemically depleted. Thermal and petrologic data indicate that Archean roots ...
• A SIMPLE MODEL FOR THE PRESSURE PRESERVATION INDEX OF INCLUSIONS IN DIAMOND 

  Barron L.M. (2003)

  The isovolume locus for a diamond-mineral inclusion pair occurs where the relative volumes of the two minerals respond identically to changes in pressure-temperature (P-T) conditions. Thirty potential inclusion minerals ...

  New high-precision isotope ratios of dissolved Mo in seawater from different ocean basins and depths show a homogeneous isotope composition (‘mean ocean water 98Mo/95Mo’ (MOMO)), as expected from its long ocean residence ...
• REACTION-ENHANCED PERMEABILITY DURING SERPENTINITE DEHYDRATION 

  Tenthorey E.; Cox S.F. (2003)

  Fluid mobilization during prograde metamorphic reactions is a poorly understood, yet crucial, phenomenon that has implications for a number of geologic problems. Here we present the first experiments to characterize ...
• THE VISIBLE DIFFUSE REFLECTANCE SPECTRUM IN RELATION TO THE COLOR AND CRYSTAL PROPERTIES OF HEMATITE 

  Torrent J.; Barrón V. (2003)

  Hematite (α-Fe2O3) possesses distinct spectral properties which facilitate its identification in mineral mixtures. This paper reports the relationships between the visible diffuse reflectance (DR) spectrum and the color ...
