Haylan, Jabal

화산대지 · Yemen · 1550m

The Jabal Haylan volcanic field comprises scoria cones and tuff rings and associated lava flows across a 75-km-long area, with a portion of the field shown in this Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 52 km across). The chain crosses a NW-SE-trending fault that with visible offset in this image. Many of the cones and rings have experienced flank collapse, rafting, or erosion, leaving amphitheater-shaped craters. Some tuff rings appear to have lava domes that have formed within the crater. · 사진: Satellite image courtesy of Planet Labs Inc., 2019 (https://www.planet.com/).

지질학적 요약

The Jabal Haylan area contains a 75-km-long chain of tuff cones and associated olivine basaltic lava flows in eastern Yemen. The chain crosses a NW-SE-trending fault extending between the highlands and desert lowlands to the east. One of the lava flows covers alluvial terraces that accumulated behind man-made dams from about 800-1200 BCE (Catalog of Active Volcanoes of the World).
