Relationship of the cristallinity index (CI) with the age and content of F and CO<sub>3</sub> ions in vertebrate fossil samples

Abstract: IntroducciónCuando los huesos quedan enterrados bajo tierra, su composición química está sujeta a cambios, unos rápidos y otros más lentos, que hacen que se destruyan o que fosilicen (Parker & Toots, 1980;Bocherens et al., 1997;Karkanas et al., 2000;Metzger et al., 2004;Carpenter, 2005 RESUMENSe ha determinado el índice de cristalinidad (IC) mediante difracción de rayos X de muestras actuales y fósiles pertenecientes a esmalte, dentina y hueso de metápodo de équidos, jiráfidos, rinocerótidos y proboscídeos de… Show more

“…The theoretical crystallite size (τ) was calculated using the Scherrer equation (Patterson 1939 ; Eq. 1 ), using 0.9 as shape factor (K), the specific wavelength (λ) provide by the XRD equipment, the line broadening half the maximum intensity (β) and the Bragg angle (θ) of the more intense plane of the calcite (104) (Person et al 1995 ; Merino and Morales 2008 ). …”
