Walther’s Law of Facies
The Walther’s Law of Facies was introduced by the German geologist Johannes Walther (1860–1937) as an important geological principle, after the establishment of the concept of “facies,” one of the foundations of modern stratigraphy. Walther’s Law states that any vertical progression of facies is the result of a succession of depositional environments that are laterally juxtaposed to each other.
The various deposits of the same facies-area and similarly the sum of the rocks of different facies-areas are formed beside each other in space, though in a cross section we see them lying on top of each other. As with biotypes, it is a basic statement of far reaching significance that only those facies and facies-areas can be superimposed primarily which can be observed beside each other at the present time.
