    tangential contact tells about the older side whereas truncating side tells about the younger side. In the given fold Diagram, you can see that cross bed is showing tangential contact towards the core of the fold. It means that older rocks are in the core of the fold i.e. an Anticline. Overall fold structure can be named as Synformal Anticline.

    Answer: 50° It is given that the pitch of the linear structure is 90°. If pitch of any linear structure is 90° then the plunge amount will be equal to the dip amount of the bed. The attitude of the bed is 50°, so the plunge amount will also be equal to 50°.

  • Owishi Sarkar Best Answer

    The plunge should be 50° that is equal to dip amount as pitch of a linear structure is the angle made with strike line and plunge is the vertical angle made with horizontal plane by the linear feature.
