Figure F43. A. Lithostratigraphic schematic representation, Hole U1349A. Light brown shading = intervals interpreted to be subaerially weathered flow tops. B. X-ray diffraction spectrum of bulk rock indicating that the rock is predominantly composed of hematite (Fe2O3), goethite (FeO[OH]), sanidine, montmorillonite, and halloysite (Al2Si2O5[OH]4·2H2O) (Sample 324-U1349A-10R-1, 10–13 cm).
