A clast of granite taken from a conglomerate is determined by radiometric dating to be one hundred
  million years old. What, if anything, does this tell you about the age of the conglomerate? What will be an ideal response?



Question 2

How are marker beds used to determine the age of strata in a region that has no marker beds but does
  contain strata with the same fossil assemblage zone? What will be an ideal response?

Answer to Question 1

The sedimentary rock is less than 100 million years old.

Answer to Question 2

Marker beds are dated with radiometric techniques. Marker beds that encompass a fossil zone in one
region can then be used to define the duration of that zone in regions where the marker beds do not
occur.
