Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy. How to Dress up Like a Soldier. Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died. The absolute dating is more reliable than the relative dating, which merely puts the different events in the time order and explains one using the other.
