Map and Photo Questions

Map 1

Label all the major structural features: For folds draw the fold axes and show with an arrow the direction of plunge (if any). Write the type of fold on the fold axis line. Place and orient appropriately strike and dip symbols along any resistant rock ridges. For faults, draw lines along the fault, label the upthrown and downthrown sides if dip slip motion dominates or with arrows show the relative direction of fault movement if strike slip movement dominates.
Map 2

Label all the major structural features: For folds draw the fold axes and show with an arrow the direction of plunge (if any). Write the type of fold on the fold axis line. Place and orient appropriately strike and dip symbols along any resistant rock ridges. For faults, draw lines along the fault, label the upthrown and downthrown sides if dip slip motion dominates or with arrows show the relative direction of fault movement if strike slip movement dominates.
Map 3

Label all the major structural features: For folds draw the fold axes and show with an arrow the direction of plunge (if any). Write the type of fold on the fold axis line. Place and orient appropriately strike and dip symbols along any resistant rock ridges. For faults, draw lines along the fault, label the upthrown and downthrown sides if dip slip motion dominates or with arrows show the relative direction of fault movement if strike slip movement dominates.
