This project combines outcrop and modern analogue studies of microbial lacustrine systems with new-generation numerical stratigraphic forward modelling.
Outcrop studies focus on Upper Jurassic (Purbeck Limestone) strata in Dorset, Southern England. The Purbeck microbialite strata occur within the syn-rift succession of the Wessex Basin associated with Upper Jurassic-Lower Cretaceous lagoonal evaporites, humid soils and lacustrine facies.
Numerical stratigraphic forward modelling will be used to explore the likely genetic controls on both large scale tectonically influenced architecture of lacustrine carbonate strata and small-scale architecture related to mound development. Modelling of tectonic influence will aim to reproduce and understand the possible variation in stratal architecture developed in response to large-scale tectonic control such as differential subsidence across and along faults and tilting of fault blocks using the Dorset outcrop examples as a test case. Modelling of small-scale facies variation will aim to reproduce and understand processes of mound formation related to clustering and spatial self-organization of carbonate production.
