Messinian foraminiferal stable oxygen and carbon isotopes of the Montemayor-1 core(Guadalquivir Basin, SW Spain) have been investigated. This record is exceptional tostudy the Mediterranean Outflow Water (MOW) impact on the Atlantic meridional overturning circulation (AMOC) and global climate during the Messinian because the core is near the Guadalhorce Corridor, the last Betic gateway to be closed during the early Messinian. Our results allow dating accurately its closure at 6.18 Ma. Constant benthic d18O values, high difference between benthic and planktonic d18O, and low sedimentation rates before 6.18 Ma indicate the presence of a two-layer water column, with bottom | Messinian foraminiferal stable oxygen and carbon isotopes of the Montemayor-1 core(Guadalquivir Basin, SW Spain) have been investigated.
