Lab 9: High grade terranes Fall 2005 1 Superposed folds Fold interference patterns are seen at all scales, from thin section to regional scale maps. Below is a map of a por- tion of the Connecticut Valley synclinorium (map digitized from Marshak and Mitra). Assume the stippled area is compositional (i.e. its either bedding or a transposition foliation). How many generations of folds are shown? Label every generation of the axial surface. Some axial surfaces have already been marked, add additional ones if necessary, and name them as F2, F3, etc. Based on the structural information shown on the map, which way 45 39 40 45 25 35 65 55 25 65 20 18 18 10 20 15 15 26 15 25 47 64 27 30 35 25 30 60 30 20 30 30 25 30 20 20 20 28 40 25 20 05 35 30 40 35 25 35 25 35 0 2 4 km does the lastest fold plunge.
