Qualitative and quantitative assessment of stratigraphic gaps in a field based study, with examples from the Lower Silurian Pentamerus Beds of Shropshire, England and the Lower Ordovician Ribband Gp of County Wexford, Ireland -- British Pennsylvanian (Carboniferous) coal-bearing sequences: where is the time? -- Use of carbon accumulation rates to estimate the duration of coal seams and the influence of atmospheric dust deposition on coal composition. The superposition of stratified rocks is an unmistakable manifestation of the history of sedimentary processes through deep time. However, the relationship between the preserved strata of the rock record and the passage of geological time, indisputable in principle, is unknowable in detail; incompleteness is an essential property of the record. That gaps exist at all scales in sedimentary successions is easily demonstrated from consideration of sediment accumulation rates, and expectations of continuity and completeness at any scale are correspondingly inadvisable. Locating and quantifying the gaps in the record is, however, very much less straightforward. Predictive modelling of strata - essential for their practical exploitation - requires such geohistorical understanding, yet over-simplified assumptions about how time is represented in rock can still lead to inadequate or even false conclusions. The contributions to this volume describe a range of practical studies, theoretical investigations, and numerical experiments in which the nature of the strata-time relationship is explored |
