Data Report: Geochemical Logging through an Accretionary Prism: Chile Triple Junction

Abstract

Geochemical well logs were obtained through sediments at Leg 141 Sites 859 and 863. Corrections have been applied to the logs to account for variations in borehole size, drilling-fluid composition, and drill-pipe attenuation. Concentrations of Th, U, and Gd, as well as oxide weight percentages, have been calculated from the logs and compared with shipboard and shorebased X-ray-fluorescence (XRF) and carbonate bomb core measurements. The geochemical processing was performed in both open hole and cased sections of Holes 859B and 863B. Comparison of XRF core data to log data is good.
