Facies Diagnosis and Facies Models
1982Microfacies types document differences in the kind of and significance of sedimentological (affecting sediment) and biological (affecting organisms) environmental factors. Although during the genesis of facies units there is an interplay of several factors, some environmental factors — especially in marine areas — seem to be of major importance.

Clastic facies models and facies analysis
Geological Society, London, Special Publications, 1985Summary The term facies is used either descriptively, for a certain volume of sediment, or interpretatively for the inferred depositional environment of that sediment. Facies models are intellectual aids to the understanding of sedimentary environments and the origin of ancient sedimentary rocks.

Metamorphic Facies and Facies Series
1965Goldschmidt’s (1911) study of the contact metamorphism of the Oslo area and Eskola’s (1914) study of the regional metamorphism of the Orijarvi region revealed that well-recrystallized metamorphic rocks approached chemical equilibrium at a stage of their history and that the mineral compositions they acquired then have usually been preserved over long ...

Studia Logica, 1996
The authors draw a distinction between two kinds of defeasible conditional obligation: those in which the condition merely provides a reasonable indicator of the existence of the obligation (which they term ``epistemic''), and those in which the condition provides a ``reason for the existence of the obligation'' (called ``constitutive''). They see this

Chapter 13 Contourite Facies and the Facies Model
2008Publisher Summary This chapter reviews the historical context and describes the different contourite facies recognized. The contourite facies models are outlined and the interpretation of contourite sequences is discussed. Some hybrid contourite facies are considered and criteria for the distinction between contourites and associated facies in deep ...

The zeolite facies; an interpretation
American Journal of Science, 1961The zeolite facies, formed under conditions intermediate between diagenesis and regional metamorphism, is characterized by mineral assemblages bearing laumontite, heulandite, or analcite, together with quartz. If H 2 O and CO 2 are regarded as mobile components, these assemblages, under the same conditions, rule out the following: calcite-kaolinite ...

Upscaling facies models to preserve connectivity of designated facies
Hydrogeology Journal, 2010An upscaling algorithm has been developed that generates an irregular coarse grid that preserves flow connectivity by applying a rule-based upscaling algorithm to a fine-scale facies distribution. The algorithm is demonstrated using stochastically generated paleo-fluvial facies distributions.

Facies versus Seismic Facies: Case Studies
Proceedings, 2013The presentation will touch upon the comparison of well based and seismic interpretation models on the example of two hydrocarbon fields in Pechora oil and gas basin. It shows that the latter provides much more accurate lateral distribution of reservoirs in the inter well space.

Shallow-marine carbonate facies and facies models
Geological Society, London, Special Publications, 1985Summary Shallow-marine carbonate sediments occur in three settings: platforms, shelves and ramps. The facies patterns and sequences in these settings are distinctive. However, one type of setting can develop into another through sedimentational or tectonic processes and, in the geologic record, intermediate cases are common.
