• We report on a paleomagnetic and rock magnetic study of two adjacent marine gravity cores from the Salerno Gulf (Italy), with measurements carried out on u-channel samples at 1 cm spacing. The cores recover a sedimentary sequence spanning, in the overlapping part, the last 6000 years and include a thick (1 m) pumice layer produced during the Somma-Vesuvius eruption of 79 A.D. Rock magnetic and lithostratigraphic data provide several tie points for a detailed correlation between the two cores. Paleomagnetic data allow the determination of a well-defined characteristic remanent magnetization, with very similar stratigraphic trends and distinct features that can also be unambiguously correlated between the cores. However, the comparison of the various data sets points out that the paleomagnetic lock in depth in the two adjacent cores varies through the stratigraphic succession. We discuss the implication of such results for assessing the potential of high-resolution paleomagnetic studies in dating sedimentary sequences on the basis of paleosecular variation of the geomagnetic field. In the studied case, the relative difference in the lock in depth in the two cores causes spreading of the assigned paleomagnetic ages at a century scale. Paleomagnetic data allow the determination of a well-defined characteristic remanent magnetization, with very similar stratigraphic trends and distinct features that can also be unambiguously correlated between the cores.

Abstract

• We report on a paleomagnetic and rock magnetic study of two adjacent marine gravity cores from the Salerno Gulf (Italy), with measurements carried out on u-channel samples at 1-cm spacing. The cores recover a sedimentary sequence spanning, in the overlapping part, the last ?6000 years and include a thick (?1 m) pumice layer produced during the Somma-Vesuvius eruption of 79 A.D. Rock magnetic and lithostratigraphic data provide several tie-points for a detailed correlation between the two cores. Paleomagnetic data allow the determination of a well-defined characteristic remanent magnetization, with very similar stratigraphic trends and distinct features that can also be unambiguously correlated between the cores. However, the comparison of the various data sets points out that the paleomagnetic lock-in depth in the two adjacent cores varies through the stratigraphic succession. We discuss the implication of such results for assessing the potential of high-resolution paleomagnetic studies in dating sedimentary sequences on the basis of paleosecular variation of the geomagnetic field. In the studied case, the relative difference in the lock-in depth in the two cores causes ''spreading'' of the assigned paleomagnetic ages at a century scale. (literal)
