BackgroundThe Zubair group is the subaerial part of a volcanic shield that from a shallow platform in the Red Sea rift. The platform and eruptive vents forming the islands are oriented NNW-SSE parallel to the rift.
An early explosive phase was followed by a brief period of marine erosion, and then by renewed explosive activity accompanied by the extrusion of basaltic pahoehoe lava flows. This latest phase of activity occurred on the morphologically youngest islands of Zubair, Centre Peak, Saba, and Haycock. Spatter cones and pyroclastic cones were erupted along fissures that form the low spine of Zubair Island.
