Figure F18. Felsic material filling fractures and surrounding angular fragments, Core 176-735B-110R-4, 10-50 cm. The image on the left is an unrolled core scan. A close-up image of the flat surface of the split piece of rock, and of one above it, is to the right of the core scan. These are compared with the a plot of magnetic susceptibility vs. depth of the same interval of rock. Background measurements are given by the dots.
