Make a sketch map of a dome, a basin, an upright synform and a plunging upright synformal antiform.
What will be an ideal response?
Answer: See Figure Q11.1. Note that younging direction is essential for identifying a synformal antiform. A dome exposes the lower unit in its center, but it does not have to be the oldest (it could be tetonostratigraphy or inverted stratigraphy for that matter). Similarly, a basin exposes the uppermost layer in the core. It is usually the youngest, but it does not have to be. The upright syncline shows a symmetric map pattern, since the two limbs are dipping the same amount at any given distance from the axial plane. Always draw a profile to test that your sketch map is correct.
