The present paper shows that the fundamentals of sequence stratigraphy were first set forth in the work of N. The fundamentals of the facies law, known in the West as Walther's Law and in Russia as Golovkinsky-Walther's Law, were also described in Golovkinsky's work long before Walther drew his conclusions on this subject.

A reliable facies description of an outcrop in the field would include: composition, texture, sedimentary structure(s), bedding geometry, nature of bedding contact, fossil content and colour.

Sedimentary facies are described in a group of "facies descriptors" which must be distinct, reproducible and exhaustive. retains an h in the spelling of hour but not in the pronunciation. Discrete seismic units are similarly referred to as seismic facies. For example, characteristic associations of organic microfossils, and particulate organic material, in rocks or sediments, are called palynofacies. Since its inception in 1838, the facies concept has been extended to related geological concepts. Sedimentary facies reflect their depositional environment, each facies being a distinct kind of sediment for that area or environment. The characteristics of the rock unit come from the depositional environment and from the original composition. Facies based on petrological characters (such as grain size and mineralogy) are called lithofacies, whereas facies based on fossil content are called biofacies.Ī facies is usually further subdivided, for example, one might refer to a "tan, cross-bedded oolitic limestone facies" or a " shale facies". Generally, geologists distinguish facies by the aspect of the rock or sediment being studied. Sedimentary facies are bodies of sediment that are recognizably distinct from adjacent sediments that resulted from different depositional environments. Sedimentary facies are either descriptive or interpretative.

Ideally, a sedimentary facies is a distinctive rock unit that forms under certain conditions of sedimentation, reflecting a particular process or environment.
