    Basalt is dark, fine-grained and often vesicular (having gas pockets). The pockets may be filled with secondary minerals, e.g. quartz, zeolite minerals, calcite, opal, etc. and then it is called amygdaloidal (a-mig-duh-loy-dal) basalt. The name may have originated with Pliny who used the Ethiopian word basal for iron-bearing rocks. (*) Basalt
