Crustal Deformation Lab AnswersPart A (2 pts each)1.C2.B3.BPart B (going from left to right)1-You just trace each contact around the right side of the block. (1pt)2-It is horizontal strata, so the map symbol would be the plus sign in the circle. For fault movement, the arrow on the right side of the fault needs to be pointing downward and be parallel to the fault plane and the arrow on the left side should be pointing upward and be parallel to the fault plane. (2 pts)3- Normal Fault (1 pt)1- Trace the fault down the right side of the block.2- Need to indicate fault movement by putting arrows parallel to fault plane. The arrow on top would be pointing to the left, and the arrow on bottom would be pointing toward the right.3- Strike-slip fault or Left-lateral strike-slip fault.1-Trace the contacts along the top of the block and the right side of the block.2- You would put an anticline axis symbol or plunging anticline axis symbol in the top center afteryou drew in the contacts. You also need strike and dip symbols making sure the symbols are showing the limbs dipping away from the axial plane.3- Depending on how you drew in your contact lines this can be an anticline or plunging anticline.1- Draw the contacts along the front and right side of the block if needed. Keep in mind the ages of the “strata.” You see that the center of the fold is the “M” because it repeats other ages on both sides. We know that “M” represents Mississippian, “S” represents Silurian, “D” represents
