Ar-Ar ages of iceberg-rafted debris from Scotia Sea IODP Site 382-U1538
Ar-Ar ages of 58 individual hornblendes and micas picked from a discrete iceberg-rafted layer deposited ~1.2 Ma at IODP U1538. The layer was recovered 310.79–310.82 meters below... -
(Table 2) Argon plateau and isochron ages of ODP Hole 165-1001A
Section 165-1001A-54R-7 was analyzed using the AEI MS-10S and Sections 165-1001A-53R-3 and 165-1001A-56R-3 were analyzed using the MAP 215-50. Ages are corrected for 37Ar decay,... -
