The facies models are the most powerful method for the genetic interpretation of the stratigraphic record, acting as syntheses of the facies relationships. Nowadays, the facies relationship interpretation is fundamented either by the Walther's Law (or Facies Correlation Law) or by the application of geostatistic tests. On the other hand, the present stratigraphic basin analysis search for stratal discontinuities (actually bedding surfaces). It is the bedding surface hierarchization, according to its physical magnitude (scale), that have revealed a usefull way for the facies association diagnosis. In accordance to this practise, it is adopted the postulate of that facies contained between bedding surfaces of the same hierarchical order, in one stratigraphic succession, without the intervenience of a bedding surface of greater magnitute, are genetically related one to each other, and may be conceived in association. This postulate differs from the universalized facies diagnosis procedures for not making use of the magnitude of the stratal discontinuities as a physical argument of the facies relationship falsification (unconformities in the Walther's Law), but as the foundation of its interpretation; furthermore, it takes away the necessity of geostatistic tests as an argument to the relationship verification, which only determines the possible and probable relations.

The Fox Bay formation crops out over much of West Falkland and the northern half of East Falkland. Fossil invertebrates from this formation resemble those from some Brazilian localities, which are predominantly of Emsian age (Melo, 1988). However the inception of certain key chitinozoans and spores into the much higher-latitude Fox Bay sequence seems greatly delayed (Marshall, 2000), suggesting that its lower part could be considerably earlier (perhaps even extending into the Pragian). The coastal section at Port North exposes a ...
