the stromboli volcano is an active volcano.
what type of volcano is the stromboli volcano?
active
stromboli stands 926 m (3,038 ft) above sea level,









































and over 2,700 m (8,860 ft) on average above the sea floor. there are three active craters at the peak. a significant geological feature of the volcano is the sciara del fuoco ("stream of fire"), a big horseshoe-shaped depression generated in the last 13,000 years by several collapses on the northwestern side of the cone. approximately 2 km (1.2 mi) to the northeast lies strombolicchio, the volcanic plug remnant of the original volcano.

stromboli
one of the important factors that can increase the portion of forsterite in the olivine solid solution is the ratio of iron(ii) ions to iron(iii) ions in the magma. as the iron(ii) ions oxidize and become iron(iii) ions, iron(iii) ions cannot form olivine because of their 3+ charge. the occurrence of forsterite due to the oxidation of iron was observed in the stromboli volcano in italy. as the volcano fractured, gases and volatiles escaped from the magma chamber. the crystallization temperature of the magma increased as the gases escaped. because iron(ii) ions were oxidized in the stromboli magma, little iron(ii) was available to form fe-rich olivine (fayalite). hence, the crystallizing olivine was mg-rich, and igneous rocks rich in forsterite were formed.
