Below the melt lens of fast spreading ridges, a low seismic velocity zone has been identified. From the study of ophiolite gabbros, in particular in Oman, this domain has been interpreted as a large magma chamber filled by a melt‐poor mush where granular flow controlled by pressure solution‐crystall
