1. CONCENTRIC FOLDS
 
 

Assuming concentric folding, draw in the folds withyour compass. The following real dips were recorded along the profile:
 
 

A: 6deg. N

 B: 13deg. N

 C: 42deg. N

 D: 76deg. S (inverted bed)

 E: 32deg. N

 F: 13deg. N

 G: 9deg. S
 
 

H: Well site: at 625 m depth: 81deg. N (inverted)

 at 812 m depth: 60deg. S

 at 1837 m depth: 18deg. S

3. GEOLOGICAL CROSS-SECTION

Following the steps outlined in previous cross-section exercises, construct a geological profile between points A and B in the accompanying map. In one paragraph, give a brief account of the geological history of the region.
