Clay minerals are ubiquitous and are the most abundant secondary products, present in all four modes discussed above. Clay minerals were determined optically, following the criteria of Honnorez et al. (1983) and Laverne et al.

secondary mineral A mineral formed by the subsolidus alteration of a pre existing primary mineral in an igneous rock. Minerals which have crystallized from a magma are stable only at high temperature and can readily alter to lowtemperature, secondary minerals when a fluid, e.g. water, is introduced into the rock system. The fluid acts as a catalyst to initiate the alteration reaction.

In addition, rock dissolution was found to affect the rigidity of the basalt samples negatively.
