... production behavior from year to year. The metamorphosed basalt is dominated by paramagnetic minerals such as chlorite and Fe-bearing prehnite, which form a frame supporting the present pore system. The large vesicles (~mm), initially created by the degassing of the magma, appear as characteristically...
