|Figure 5-8. A: Two sets of small stylolites (small black arrows) truncated by one stylolite (large black arrow) in an Ordovician dolostone. Note greater thickness of the cross-cutting stylolite at the black arrows itself; this presumably resulted from accumulation of the insoluble residue of the two stylolites to the right. Area in blue rectangle is shown in B. Red marks are guide marks left from thesis work by Lynn M. Andrews.
B: Higher-magnification view of area in blue rectangle in A. Arrows show directions of compression along each stylolite. Earlier stylolites record NE-SW compression (as shown in image, not in real space), but stylolites to right of later stylolite record compression not quite parallel to that of stylolite at left, suggesting they did not form simultaneously. Later stylolite in middle records NW-SE compression.
Image was scanned directly from sample. East Sweetwater, Tennessee, U.S.A.; Sample TN6-16D. Sample collected by L. Bruce Railsback and Lynn M. Andrews.
