The volcanic field contains basaltic scoria cones, tuff rings, maars, lava domes and lava flows. Beschreibung:Most of the Harrat Kishb volcanic field is of Pleistocene age. Young Holocene flows are restricted to 3 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. Harrat Kishb includes several tuff rings and maars, including the 800 x 600 m wide Al Wabah maar in the west-central part of the Harrat. The most recent products of Harrat Kishb, which include 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. (from: Smithsonian / GVP) The lava field contains a number of lava tubes, including Ghostly Cave (Kahf Al Ashbaah) and Kahf Al Mut’eb as some of the most known ones. |
