Abstract
Facies analysis and its use in sequence stratigraphy is described using the Lower Greensand of southern England as an example, and the resulting interpretations are outlined. This work forms an independent test of sequence stratigraphic techniques and the Exxon ‘cycle chart’. Sequence stratigraphy is a very powerful tool in the analysis of problematic successions, although some modification is made here in emphasizing the use of the transgressive surface. Changing palaeoenvironmental conditions, and the effect that palaeoceanography has on the recognition of sequence boundaries, are also discussed. Broad agreement is found between these results and the cycle chart, although changing tidal conditions alter the criteria available for analysis of the Aptian-Albian Lower Greensand succession. Comparison between this study and sequence stratigraphic analyses conducted in the more condensed type sections of England and France shows that further sequence boundaries are recognizable.
