Architectural element analysis of turbidite systems, and selected topical problems for sand-prone deep-water systems

Abstract

Deep-water deposits may be defined in terms of ‘architectural elements’ (cf. fluvial models of Miall 1985). In fluvial sedimentology, Miall’s (1985) ‘architectural elements’ are characterized by facies associations and three-dimensional geometry (including orientation). The identification of depositional geometry requires the classification of a hierarchy of bounding surfaces, an approach now widely accepted for fluvial and eolian deposits. Using a hierarchy of bounding surfaces, together with facies analysis and geometry, it is shown how ‘architectural element analysis’ may be used as an aid in the interpretation of deep-water systems and their depositional history.
