LA TEXTURE DES CHONDRITES OBSERVEE EN PLAQUES MINCES PAR FLUORESCENCE ULTRA-VIOLETTE

A technique of impregnation by fluorescent resins followed by observations of thin sections in U V light has been applied to the study of porosity, brecciation and shock effects in chondritic meteorites. The following chondrites have been studied: Sena, Ikhraréne, Kernouve, Koutiaran, L'Aigle, Tiberrhamine. Tentative chronological orders of tectonic events undergone by those meteorites are proposed.
