Abstract

The mineralogy and micromorphology of laterites from Central Greece have been thoroughly examined by X-ray diffraction, thermal analysis and optical microscopy. Based on these results and the field observations, the unusual occurrence of calcite and the rocky nature of the laterites are elucidated, and the mechanism of genesis is given.

Also the physical and mechanical properties of these materials were studied and a good relationship between uniaxial compressive strength and porosity was established.

Étude de la composition minéralogique, et des propriétés physiques et mécaniques de latérites Grecques

Résumé

La minéralogie et la micromorphologie des latérites de la Grèce centrale ont été étudiées par les méthodes de diffraction RX, de l'analyse thermique et du microscope optique. Ces résultats et ces observations de terrain ont permis d'expliquer la présence de calcite et la nature rocheuse des latérites, ainsi que le mécanisme de leur genèse.

Nous avons étudié aussi les propriétés physiques et mécaniques de ces matériaux et avons établi une bonne relation entre la pression uniaxiale et la porosité.
