(8 pts)  Fill in the table below to create a geologic time scale:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(4) Plot the following two planes using tracing paper on the stereonet:

 

 

(2) Do the two planes intersect? If so, mark the intersection on the stereonet and determine the orientation in space of their intersection.

 

 

 (3)   (The grid below is every 15 degrees.)

oWhich of the three great circles below has the smallest dip?

oWhich (if any) of the great circles dips to the NW?

oDo the three planes share any characteristics?

 


 

Three planes and one line are plotted on the stereonet below.  The line represents the pole to one of the three planes.  Which plane is that, and what is the approximate dip and strike of the plane represented by the great circle be?
