BeschreibungThe Harra of Arhab volcanic field (also known as the Sana'a or the Sana'a-Amran volcanic field) forms a 100-250-m-thick basaltic plateau capped by a few small stratovolcanoes and about 60 scoria cones, 2 of which have erupted in historical time.
Cones in the volcanic field are commonly aligned along a NNW trend. The ages of lavas range from Pliocene to Holocene and their chemistry is dominantly basaltic-to-hawaiitic in composition. They overlie the northern end of an area of extensive Oligocene-Miocene basaltic-to-rhyolitic rocks that extends to the SW tip of the Arabian Peninsula.
