| Sumario: | <p>The western Arabian Peninsula includes one of the world’s most extensive monogenetic volcanic provinces, with dispersed volcanic fields extending from south-eastern Türkiye to north-western Yemen. The volcanic fields exhibit significant geological diversity and a magmatic composition ranging from mafic to rare silicic. This province is primarily characterised by relatively small-volume monogenetic volcanoes formed during the Neogene–Quaternary period, resulting in the creation of over 3,000 volcanic edifices – more than 90% of which represent typical magmatic explosive and effusive activity. Additionally, the province includes remarkable examples of volcanoes formed by explosive magma–water interactions, including some of the largest maar volcanoes globally and exceptionally well-preserved phreatomagmatic tuff ring rims. In certain instances, eruptions involving more silicic magmas resulted in brief but intense explosive events triggered by lava dome explosions, in which external water likely contributed to crater formation and the production of characteristic initial eruptive materials. This chapter provides the first comprehensive summary of the fundamental features of the phreatomagmatic eruptive centres within the western Saudi Arabian Neogene–Quaternary volcanic fields, emphasising their eruptive products, landforms, and the implications for understanding their eruptive environments.</p> |
