Geologists still use Steno's principles, with some refinements and additions.
Now imagine that you come upon a formation like this: What do you think of it? How can you make any conclusions about rock layers that make such a crazy arrangement?
Relative dating uses the principles or laws of stratigraphy to order sequences of rock strata.
Relative dating not only determines which layers are older or younger, but also gives insight into the paleoenvironments that formed the particular sequence of rock.
Steno made careful geologic observations and illustrations.
He published the results of his work and established a basic set of principles for interpreting sedimentary strata.
