Figure F27. Downhole plots of structural features of Hole U1309D. A. Lithostratigraphy. B. Average intensity of magmatic and plastic foliation from core observations. C. Paleomagnetic inclination from archive-half and discrete samples. Groups I–V correspond to zones with distinct average inclinations. Parts D–I are a summary of deformation in the upper 400 m (top of scale given for each category). D. Lithology. E. Intensity of magmatic fabrics (3 = strong shape-preferred orientation). F. Intensity of crystal-plastic fabrics (4–5 = mylonitic–ultramylonitc). G. Frequency of alteration veins (5 = >20/cm). H. Intensity of cataclastic fabrics (5 = cataclasite). I. Magnetic inclination deduced from core samples that have been demagnetized to remove drilling overprint.
