Cordon del Azufre

Gunung api kompleks · Chile-Argentina · 5481 m

Cordón del Azufre is in the center of this 22 May 2019 Planet Scope satellite image (N is at the top), located along the Chile-Argentina border. The darker lava flow originated from Volcán la Moyra, the youngest feature of the volcanic field, reaching 6 km to the W. The complex includes a N-S chain of four craters and numerous lava flows.

Ringkasan geologi

Cordón del Azufre is a small volcanic complex straddling the Chile-Argentina border. The complex consists of a cluster of lava flows from vents on the NE side, wholly within Argentina, and a 5-km-long chain of vents along the border with Chile. An older andesitic-dacitic edifice with a 1.3-km-wide crater was mostly covered by younger Holocene andesitic lava flows. The youngest cone, 300-m-high Volcán la Moyra, was the source of fresh-looking blocky andesitic lava flows that descended 6 km into Chile and 3 km into Argentina.

Ringkasan Wikipedia

Cordón del Azufre adalah sebuah gunung berapi gabungan tidak aktif yang terletak di Andes Tengah, di perbatasan Argentina dan Chili. Gunung ini terdiri dari tiga tahap kerucut piroklastik dan aliran lava yang terkait, dan aktivitasnya merupakan konsekuensi dari subduksi Lempeng Nazca di bawah Lempeng Amerika Selatan. Di sebelah utaranya terdapat gunung berapi yang tidak aktif Lastarria dan wilayah Lazufre yang aktif.
