Figure F291. Preliminary structural interpretation of the Formation MicroScanner (FMS) images from Hole U1309B. FMS images are presented with a static and dynamic normalization. On the dynamic image, sinusoids that correspond to the mapped planes are shown by the red lines. The orientation tadpoles plot in the next column, where position along the horizontal axis indicates the dip (0°–90°) and the tadpole tail direction indicates the dip direction of the planar structure (south = down, north = up). Electrical resistivity (logarithmic scale), neutron porosity, density, photoelectric effect, and capture cross-section curves are also shown for comparison. In the lower right corner, the summary of the structural analysis of the FMS images is presented. The histogram shows the distribution of dip values, and the rosette diagram shows the dip direction of the planar structure identified on the FMS images. Good correlation is observed between fractured intervals on the FMS images (highly conductive intervals) and low density and electrical resistivity and high porosity.
