These average MORB compositions are calculated using a more restrictive set of filters in order to assure that MORB representing low degree melts or melts which have experienced large amounts of fractional crystallization do not affect the average.  Though degree of melting or fractional crystallization do not effect the average isotopic composition, for incompatible trace element ratios to reflect source compositions only high degree melts should be used.  These will be known as 'D-MORB' for Depleted Mid-Ocean Ridge Basalts.  It is also noted that the values of the 'Average' and 'Extreme' D-MORB are very similar. Salters & Stracke 2004

Extreme Depleted D-MORB basalts   143Nd/144Nd 0.5134             Isotopic compositions of Depleted Mantle (DM) according to Neodymium isotopes in the 'Extreme' present day MORB.  'Extreme' merely refers to the fact that these isotopic compositions are from the most depleted end of the MORB field. These average MORB compositions are calculated using a more restrictive set of filters in order to assure that MORB representing low degree melts or melts which have experienced large amounts of fractional crystallization do not affect the average.  Though degree of melting or fractional crystallization do not effect the average isotopic composition, for incompatible trace element ratios to reflect source compositions only high degree melts should be used.  These will be known as 'D-MORB' for Depleted Mid-Ocean Ridge Basalts.  It is also noted that the values of the 'Average' and 'Extreme' D-MORB are very similar. Salters & Stracke 2004

Fresh Mid-Ocean Ridge Basalts   143Nd/144Nd 0.5134             Isotopic compositions of Depleted Mantle (DM) according to Neodymium isotopic values from the 'All MORB' data compilation.  To achieve an average isotopic composition of the Depleted Mantle the PetDB database was utilized. All eruptive products from mid-ocean spreading centers were compiled and filtered to include only samples that were erupted in water depths in excess of 2000 m.  All samples that contained more than 55 wt.% SiO2 were excluded as well. Samples with non-smooth REE patterns were excluded wherever applicable.  With these minimal steps of filtering, this ensures that at least part of the plume influenced basalts are excluded.    Salters & Stracke 2004
