48 The schematic map given below shows intersecting strike lines of the same lithological contact. In the map, AB and CD are 5 cm and 3.5 cm, respectively. The scale of the map is I cm= 100 m. The plunge of the fold axis is degrees (give answer in one decimal place). D 300 m B A 300 m 400 m 400 m ate indos
Answer: Plunge = 15.94°
As shown in the diagram,
Horizontal equivalent (CD) = 3.5 × 100 = 350 m
Vertical interval = Height difference between point C and D = 400 - 300 = 100 m
