WebDec 3, 2024 · Applying the facies concept to depositional systems is crucial for interpreting ancient delta systems and unraveling the 4 th dimension – time. Thus, the definition of a depositional system, in the context of the rock record, can be expanded to include the 4-dimensional assemblage of genetically related facies. WebApr 1, 2015 · A formal definition was proposed by Jones and Damaison (1980, 1982), where an “organic facies is a detectable subdivision of a certain stratigraphic unit which can be …

[citation needed] Facies based on petrological characters (such as grain size and mineralogy) are called lithofacies, whereas facies based on fossil content are called biofacies . See more In geology, a facies is a body of rock with specified characteristics, which can be any observable attribute of rocks (such as their overall appearance, composition, or condition of formation), and the changes that may occur in … See more • Lithofacies • Metamorphic rock • Sequence stratigraphy See more Sedimentary facies Ideally, a sedimentary facies is a distinctive rock unit that forms under certain conditions of sedimentation, reflecting a particular process or environment. Sedimentary facies are either descriptive or interpretative. … See more WebThe boundaries of the middle unit or "saline facies" are the first and last salt beds found. These boundaries laterally transcend time surfaces and, as shown in figure 2, move stratigraphically higher and lower in the section on approaching the deepest part of the basin. The true depositional thickness of the "saline facies" ranges from disused sources working group
