Fig. 41. Same as Fig. 40, after (1) displacement by a strike fault, and (2) 

 base leveling. The outcrops of certain beds are repeated. 



Fig. 42. Diagram illustrating how a strike fault in such a structure as that 

 shown in Fig. 40, may cause the outcrop of certain beds to disappear. 



Fig. 43. Diagram illustrating how a dip fault in the structure shown in 

 Fig. 40 affects the outcrop when the downthrow was on the farther side 

 of the fault-plane. 



Fig. 44. Oblique fault in the structure shown in Fig. 40. The downthrow 

 was on the left side. The outcrop of layer H is offset with overlap. 



Fig. 45. Same as Fig. 43, except that the downthrow was on the right side, 

 and the offset is with a gap instead of an overlap.
