    Description: The capability of determining elemental concentrations through geochemical logging has recently been established. However, the quality of these data obtained in some environments has yet to be quantified. We assess the quality of geochemical logs compared with XRF results from a suite of core samples from Hole 798B. The resulting core/log correlations are only fair, because the tool has been adversely affected by the very high porosity of the formation. The results, however, do fall within the statistical uncertainties predicted by the processing. The recent application of a modified boron sleeve to the Ocean Drilling Program's geochemical logging tool is shown to reduce interference of borehole chlorine on the resultant chemistry.

    Description: Résumé Quatre sites ont été forés dans le talus volcanoclastique sous-marin de l'île volcanique de Gran Canaria au cours du Leg ODP 157. La sédimentation du talus enregistre l'évolution volcanique de l'île. Les grandes phases éruptives s'expriment clairement par d'importants apports clastiques contemporains au niveau du talus. En revanche, les périodes d'inactivité volcanique se traduisent par des taux de sédimentation très faibles. II est possible ainsi d'établir un découpage volcanostratigraphique à partir des sédiments marins. Abstract Four sites have been drilled in the submarine volcaniclastic apron of the volcanic island of Gran Canaria during the ODP Leg 157. The volcaniclastic submarine apron reflects the volcanological evolution of the island. The main volcanic phases are recorded in the sedimentation by an important contemporaneous clastic influx on the apron. However, periods of volcanic quiescence are characterized by very weak sedimentation rates. Consequently, it is possible to establish a volcanostratigraphy from the sedimentary record of the apron.
