Summary: The following secondary minerals occur according to XRD, IR, EM, SEM and electron diffraction: trioctahedral and dioctahedral smectite, chlorite, mixed-layer clays, talc, hematite, pyrite, faujasite, phillipsite, analcite, natrolite, thomsonite, gyrolite, aragonite, calcite, anhydrite, chalcocite, Fe-hydrosilicate, okenite, apophyllite, actinolite, cristobalite, quartz, magnesite and bismutite. A Mn-rich mineral and strong reflections at 12.9 and 3.20 A remain unidentified. Trioctahedral smectite replaces glass and olivine in the basalt matrix; the other secondary minerals occur in veins. Most of the secondary minerals formed below 120°C and show both hydrothermal and oxidizing-non-oxidizing zonation.
