Statistical analysis of geochemical logging tool data from Hole 735B, Atlantis Fracture Zone, southwest Indian Ocean

Abstract

Data derived from the geochemical logging tool (GLT) used to log the basement gabbros of Hole 735B in the Atlantis II Fracture Zone show a wide variation in geochemical composition. Statistical analysis of these data, primarily principal component analysis and iterative nonhierarchical cluster analysis (INCA), has been employed to classify these data into geochemically similar groups to produce a statistically derived chemostratigraphy for the borehole. -from Authors
