The map displays clear evidence of folding within the rock units. Repetition of Units: The most prominent evidence is the repetition of the horizontally-lined rock unit and the dotted rock unit across the map. This pattern is characteristic of folded strata where layers are exposed multiple times due to erosion. Dip and Strike Symbols: The dip and strike symbols indicate the orientation of the rock layers. In the northern part of the map, the horizontally-lined unit shows dips pointing outwards from its core (e.g., 40, 10, 40 degrees), indicating the presence of an anticline. Further south, the dotted unit exhibits dips generally pointing inwards towards its core (e.g., 30, 20, 30, 50 degrees), suggesting a syncline. Plunging Folds: The curvilinear and closing outcrop patterns of the rock units (e.g., the horizontally-lined unit closing in the northwest and the dotted unit closing in the central-east) indicate that these are plunging folds. Orientation: The fold axes generally trend in an east-west to northeast-southwest direction, as inferred from the elongation of the outcrop patterns. The varying dip angles suggest that the folds are not perfectly symmetrical.
