Resume L'eau incluse est l'un des constituants des coraux fossiles. Nous avons mesure par thermogravimetrie, la part d'eau adsorbee et surtout le pourcentage d'eau incluse qui semble constant pour les coraux qui ne contiennent que de l'aragonite (1,7

A new solution calorimeter (the Calsol) is described. This conduction calorimeter (heat fluxmeter) is differential and rotating. The sensitive part of the temperature regulator is placed between the thermostat and the outer case, and a microcomputer

The aragonite fossil corals exhibit an intense natural thermoluminescence between 300°C and 450°C. The transformation of this biogenic aragonite into calcite begins at 260°C and is completed around 450°C. It is accompanied by a rapid loss of wate

The changes in Gibbs energy, enthalpy, and entropy for the protonation of phenylalanine anion (L) and for the formation of complexes ML+ and ML2 (M = Cu2+ or Co2+) are reported for I = 1 M (Na)Cl at 25°C. The results are compared with those of other

Sedimentary phosphate apatite is a phosphocalcium carbo-apatite. For this kind of structure, two possibilities exist for PO 3− 4 CO 2− 3 replacement: one corresponds to PO 3− 4 ( CO 2− 3 , F − ) with substitution ratio x , the other one to

The molar absorption coefficients for the OH stretching vibrations of 16 hydrothermally prepared hydroxyfluorapatites Ca5(PO4)3(OH)xF1-x have been determined. The coefficients vary with composition, reaching a maximum at x = 0.8. At low OH concentrat
