Summary
[edit]DescriptionAltered scoria (Pacaya Volcano, Guatemala) 3.jpg |
English: Scoria from the Holocene of Guatemala.
Pacaya Volcano is a Pleistocene- to Holocene-aged subduction zone stratovolcano located in southern Guatemala, about 30 kilometers away from Guatemala City. The mountain is visible from the city and is frequently seen erupting. Many people climb the slopes of the volcano when it's not erupting and can observe the crater up-close. The sample seen here is altered scoria that was collected from crater rim on 8 December 2004 - the volcano had stopped erupting for a couple days. Fresh scoria is black to near-black in color - this sample's coloration is from oxidation. It's also been altered and mineral-coated from exposure to volcanic gases. Locality: edge of MacKenney Crater, Pacaya Volcano, south-southwest of Guatemala City, southern Guatemala, Central America |
