Harrat Kishb

Kishb, Harrat

Volcanic field · Saudi Arabia · 1475m

The NW part of the 5,900 km2 Harrat Kishb volcanic field is seen in this Space Shuttle image. The field is located E of a N-S-trending line of volcanic fields in central Saudi Arabia. The medium-brown-colored Jabal Aslaj scoria cone visible near the top of the dark lava flows near the center of the image was the source of the flows seen here. A second area of young flows seen at the lower right surrounds the circular Al Wahbah maar. These lava flows are stratigraphically younger than a 6,500-4,000-year-old pluvial period.

Geological summary

The 5,900 km3 Harrat Kishb volcanic field, located E of a N-S-trending line of volcanic fields in central Saudi Arabia, is comprised of basaltic scoria cones, tuff rings and maars, and phonolitic lava domes and flows. Most of it is of Pleistocene age; Holocene flows are restricted to three areas in the western half of the field. Jabal Aslaj cone and its associated lava flows contain abundant granitic blocks from basement rocks and ultramafic nodules. Jabal Hil is a large scoria cone with a 300-m-wide crater that was filled and overtopped by a lava lake. Among the several tuff rings and maars is the 800 x 600 m wide Al Wabah maar in the west-central portion of the field. The most recent products, including the scoria cones and lava flows of Jabal Aslaj and Jabal Hil and the Jabal Shalman lava-dome, lava-flow, and scoria-cone complex, are stratigraphically younger than a pluvial period dated about 6500-4000 years before present.
