Abstract
Ten international laboratories participated in an inter-laboratory comparison of a fossil bone composite with the objective of producing a matrix and structure-matched reference material for studies of the bio-mineralization of ancient fossil bone. We report the major and trace element compositions of the fossil bone composite, using in-situ method as well as various wet chemical digestion techniques. For major element concentrations, the intra-laboratory analytical precision (%RSDr) ranges from 7 to 18%, with higher percentages for Ti and K. The %RSDr are smaller than the inter-laboratory analytical precision (%RSDR; <15-30%). Trace element concentrations vary by ∼5 orders of magnitude (0.1 mgkg-1 for Th to 10,000 mg kg-1 for Ba). The intra-laboratory analytical precision %RSDr varies between 8 and 45%. The reproducibility values (%RSDR) range from 13 to <50%, although extreme value >100% was found for the high field strength elements (Hf, Th, Zr, Nb). The rare earth element (REE) concentrations, which vary over 3 orders of magnitude, have %RSDr and %RSDR values at 8-15% and 20-32%, respectively. However, the REE patterns (which are very important for paleo-environmental, taphonomic and paleo-oceanographic analyses) are much more consistent. These data suggest that the complex and unpredictable nature of the mineralogical and chemical composition of fossil bone makes it difficult to set-up and calibrate analytical instruments using conventional standards, and may result in non-spectral matrix effects. We propose an analytical protocol that can be employed in future inter-laboratory studies to produce a certified fossil bone geochemical standard.

We report the major and trace element compositions of the fossil bone composite, using in-situ method as well as various wet chemical digestion techniques. For major element concentrations, the intra-laboratory analytical precision (%RSD<sub>r</sub>) ranges from 7 to 18%, with higher percentages for Ti and K. The %RSD<sub>r</sub> are smaller than the inter-laboratory analytical precision (%RSD<sub>R</sub>; <15-30%). Trace element concentrations vary by ∼5 orders of magnitude (0.1 mgkg<sup>-1</sup> for Th to 10,000 mg kg<sup>-1</sup> for Ba). The intra-laboratory analytical precision %RSD<sub>r</sub> varies between 8 and 45%. The reproducibility values (%RSD<sub>R</sub>) range from 13 to <50%, although extreme value >100% was found for the high field strength elements (Hf, Th, Zr, Nb). The rare earth element (REE) concentrations, which vary over 3 orders of magnitude, have %RSD<sub>r</sub> and %RSD<sub>R</sub> values at 8-15% and 20-32%, respectively. However, the REE patterns (which are very important for paleo-environmental, taphonomic and paleo-oceanographic analyses) are much more consistent. These data suggest that the complex and unpredictable nature of the mineralogical and chemical composition of fossil bone makes it difficult to set-up and calibrate analytical instruments using conventional standards, and may result in non-spectral matrix effects. We propose an analytical protocol that can be employed in future inter-laboratory studies to produce a certified fossil bone geochemical standard.</s0></fC01><fC02 i1="01" i2="X"><s0>001D16E</s0></fC02><fC02 i1="02" i2="X"><s0>001C04A</s0></fC02><fC03 i1="01" i2="X" l="FRE"><s0>Etude comparative</s0><s5>01</s5></fC03><fC03 i1="01" i2="X" l="ENG"><s0>Comparative study</s0><s5>01</s5></fC03><fC03 i1="01" i2="X" l="SPA"><s0>Estudio comparativo</s0><s5>01</s5></fC03><fC03 i1="02" i2="X" l="FRE"><s0>Matériau référence</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="ENG"><s0>Reference material</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="SPA"><s0>Material referencia</s0><s5>02</s5></fC03><fC03 i1="03" i2="X" l="FRE"><s0>Minéralisation</s0><s5>03</s5></fC03><fC03 i1="03" i2="X" l="ENG"><s0>Mineralization</s0><s5>03</s5></fC03><fC03 i1="03" i2="X" l="SPA"><s0>Mineralización</s0><s5>03</s5></fC03><fC03 i1="04" i2="X" l="FRE"><s0>Constituant principal</s0><s5>04</s5></fC03><fC03 i1="04" i2="X" l="ENG"><s0>Major constituent</s0><s5>04</s5></fC03><fC03 i1="04" i2="X" l="SPA"><s0>Constituyente principal</s0><s5>04</s5></fC03><fC03 i1="05" i2="X" l="FRE"><s0>Elément trace</s0><s5>05</s5></fC03><fC03 i1="05" i2="X" l="ENG"><s0>Trace element</s0><s5>05</s5></fC03><fC03 i1="05" i2="X" l="SPA"><s0>Elemento traza</s0><s5>05</s5></fC03><fC03 i1="06" i2="X" l="FRE"><s0>In situ</s0><s5>06</s5></fC03><fC03 i1="06" i2="X" l="ENG"><s0>In situ</s0><s5>06</s5></fC03><fC03 i1="06" i2="X" l="SPA"><s0>In situ</s0><s5>06</s5></fC03><fC03 i1="07" i2="X" l="FRE"><s0>Digestion</s0><s5>07</s5></fC03><fC03 i1="07" i2="X" l="ENG"><s0>Digestion</s0><s5>07</s5></fC03><fC03 i1="07" i2="X" l="SPA"><s0>Digestión</s0><s5>07</s5></fC03><fC03 i1="08" i2="X" l="FRE"><s0>Reproductibilité</s0><s5>08</s5></fC03><fC03 i1="08" i2="X" l="ENG"><s0>Reproducibility</s0><s5>08</s5></fC03><fC03 i1="08" i2="X" l="SPA"><s0>Reproductividad</s0><s5>08</s5></fC03><fC03 i1="09" i2="X" l="FRE"><s0>Lanthanide</s0><s2>NC</s2><s5>09</s5></fC03><fC03 i1="09" i2="X" l="ENG"><s0>Lanthanide</s0><s2>NC</s2><s5>09</s5></fC03><fC03 i1="09" i2="X" l="SPA"><s0>Lantánido</s0><s2>NC</s2><s5>09</s5></fC03><fC03 i1="10" i2="X" l="FRE"><s0>Environnement</s0><s5>10</s5></fC03><fC03 i1="10" i2="X" l="ENG"><s0>Environment</s0><s5>10</s5></fC03><fC03 i1="10" i2="X" l="SPA"><s0>Medio ambiente</s0><s5>10</s5></fC03><fC03 i1="11" i2="X" l="FRE"><s0>Composition minéralogique</s0><s5>11</s5></fC03><fC03 i1="11" i2="X" l="ENG"><s0>Mineralogical composition</s0><s5>11</s5></fC03><fC03 i1="11" i2="X" l="SPA"><s0>Composición mineralógica</s0><s5>11</s5></fC03><fC03 i1="12" i2="X" l="FRE"><s0>Composition chimique</s0><s5>12</s5></fC03><fC03 i1="12" i2="X" l="ENG"><s0>Chemical composition</s0><s5>12</s5></fC03><fC03 i1="12" i2="X" l="SPA"><s0>Composición química</s0><s5>12</s5></fC03><fC03 i1="13" i2="X" l="FRE"><s0>Appareillage</s0><s5>13</s5></fC03><fC03 i1="13" i2="X" l="ENG"><s0>Instrumentation</s0><s5>13</s5></fC03><fC03 i1="13" i2="X" l="SPA"><s0>Instrumentación</s0><s5>13</s5></fC03><fC03 i1="14" i2="X" l="FRE"><s0>Effet matrice</s0><s5>14</s5></fC03><fC03 i1="14" i2="X" l="ENG"><s0>Matrix effect</s0><s5>14</s5></fC03><fC03 i1="14" i2="X" l="SPA"><s0>Efecto matriz</s0><s5>14</s5></fC03><fC03 i1="15" i2="X" l="FRE"><s0>Phosphate</s0><s2>NA</s2><s5>15</s5></fC03><fC03 i1="15" i2="X" l="ENG"><s0>Phosphates</s0><s2>NA</s2><s5>15</s5></fC03><fC03 i1="15" i2="X" l="SPA"><s0>Fosfato</s0><s2>NA</s2><s5>15</s5></fC03><fC03 i1="16" i2="X" l="FRE"><s0>Fossile</s0><s5>22</s5></fC03><fC03 i1="16" i2="X" l="ENG"><s0>Fossil</s0><s5>22</s5></fC03><fC03 i1="16" i2="X" l="SPA"><s0>Fósil</s0><s5>22</s5></fC03><fC03 i1="17" i2="X" l="FRE"><s0>Os</s0><s5>23</s5></fC03><fC03 i1="17" i2="X" l="ENG"><s0>Bone</s0><s5>23</s5></fC03><fC03 i1="17" i2="X" l="SPA"><s0>Hueso</s0><s5>23</s5></fC03><fC03 i1="18" i2="3" l="FRE"><s0>Comparaison interlaboratoire</s0><s5>24</s5></fC03><fC03 i1="18" i2="3" l="ENG"><s0>Interlaboratory comparisons</s0><s5>24</s5></fC03><fC03 i1="19" i2="X" l="FRE"><s0>Géochimie</s0><s5>25</s5></fC03><fC03 i1="19" i2="X" l="ENG"><s0>Geochemistry</s0><s5>25</s5></fC03><fC03 i1="19" i2="X" l="SPA"><s0>Geoquímica</s0><s5>25</s5></fC03><fN21><s1>344</s1></fN21></pA></standard><server><NO>PASCAL 07-0535019 INIST</NO><ET>Towards the development of a fossil bone geochemical standard : An inter-laboratory study</ET><AU>CHAVAGNAC (V.); MILTON (J.
