The Yemen Volcanic Group consists of a series of volcanic rocks in Yemen, ranging from basalt to rhyolite, that formed during the Tertiary period. These volcanic rocks are significant in volcanology and tectonics for understanding the processes of continental rifting, the formation of the Red Sea and Gulf of Aden, and the evolution of the Arabian Peninsula.
