来自用于记录亚特兰蒂斯 II 断裂带 735B 孔基底辉长岩的地球化学测井仪 (GLT) 的数据显示，地球化学成分存在很大差异。这些数据的统计分析，主要是主成分分析和迭代非层次聚类分析（INCA），已被用来将这些数据分类为地球化学相似的组，以产生统计得出的钻孔化学地层学。得出的化学地层学与船载科学小组（SSP，1989）进行的岩心标本研究所定义的岩石地层学非常一致，但此外还突出了钻孔中一些明显的地球化学异常区域，这应该是进一步检查的重点。
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. The derived chemostratigraphy is in excellent agreement with the lithostratigraphy defined from study of core specimens conducted by the Shipboard Scientific Party (SSP, 1989), but in addition highlights some apparently geochemically anomalous regions in the borehole, which should be the focus for further examination.
