Abstract

Geological material, of greenish color, filling interspaces in altered Triassic pillow lavas of Lamia area (central Greece) was studied, for the first time in the literature. According to XRD and SEM-EDS data it predominantly consists of calcite, zeolites and clay minerals. The zeolites concern thomsonite and analcime. The clay minerals, on the basis of XRD, FTIR and Mössbauer spectroscopic measurements, constitute a Fe-bearing phase of the illlite-glauconite-celadonite group (most likely Fe-illite).
