  • Changes in magma composition at Arenal volcano, Costa Rica ...

    Arenal volcano in Costa Rica has been erupting nearly continuously, but at a diminishing rate, since 1968, producing approximately km3 of lavas and tephras that have shown consistent variations in chemistry and mineralogy. From the beginning of the eruption in July 1968 to early 1970 (stage 1, vol.= km3) tephras and lavas became richer in Ca, Mg, Ni, Cr, Fe, Ti, V, .
