Figure F27. Downhole plots of structural features. A. Average intensity of magmatic and plastic foliation from core observations. B. Dip of magmatic and plastic foliations. Magmatic foliations above 400 mbsf show a random dip, between 400 and 600 mbsf the dip steadily increases from 20° to 60°, from 600 to 800 mbsf there is a general decrease in the dip from 60° to 40°, between 800 and 1100 mbsf there is again a steady increase in the dip from 20° to 60°, from 1100 to 1200 there is steep decline in dip from 60° to 10°, and from 1200 mbsf to the bottom of the hole there is a gradual increase in the dip up to a maximum of ~60°. Plastic foliations show a general decrease in the dip from 70° to 0° between 0 and 700 mbsf and an increase in the dip from 700 mbsf to the bottom. C. Dip of compositional layers, grain size layers, and oxide bands. D. Dip of magmatic veins, igneous contacts, and alteration fronts. The column on the right corresponds to the lithostratigraphy.
