Abstract

The formation of the central calderas of the Alba Patera summit area is proposed to have been caused by collapse(s) into relatively shallow and wide magma chamber(s). The subduction or collapse of the whole central Alba Patera area and the formation of peripheral circular fossae grabens around it were caused by a deeper, wider and more primary magmatic process which was more directly connected to the ascending hot mantle.
