Iliniza

成層火山 · Ecuador · 5162m

The twin peaks of Illiniza volcano form prominent landmarks west of the Interandean Valley. Sharp-peaked, snow-covered Illiniza Sur (right) is the higher of the two peaks. It is seen here from the south with Illiniza Norte to its left. Illiniza is largely, if not entirely Pleistocene in age. However, Rasuyacu lava dome on the south flank was active during the Holocene. Recent work suggests that Illiniza itself, which is substantially eroded, may have had relatively young eruptions.

地質学的概要

The two glacier-covered peaks of Iliniza volcano are prominent landmarks west of the Interandean Valley. The smaller Iliniza Norte is a remnant of the main volcanic edifice located 1.8 km NNW of the younger Iliniza Sur, an andesitic-dacitic stratovolcano surrounded by thick pyroclastic-flow deposits. The edifice is mainly Pleistocene, though the Tishigcuchi (Rasuyacu) lava dome on the S flank was active during the Holocene. Iliniza itself, which is substantially eroded, may also have had relatively young eruptions (Hall, 1987, pers. comm.). A lava dome forms the summit of Iliniza Sur, and two more lava domes are found on the southern and NE flanks of the complex.

The Illinizas are a pair of volcanic mountains that are located in the north of Latacunga, Cotopaxi, Ecuador. They are located in the Illinizas Ecological Reserve. These twin mountains are separated by a saddle that is about a kilometer long. The peaks are among the highest in Ecuador, with Illiniza Sur standing slightly taller than Illiniza Norte, its northern counterpart, at 5248 metres and 5126 metres respectively.
