Abstract

A basin-wide sequence stratigraphy for the Middle Jurassic has been developed, comprising two tectono-stratigraphic units (J20, Aalenian-Late Bajocian and J30, latest Bajocian-Middle Callovian), subdivided into five sequences: J22 (Aalenian), J24 (Early Bajocian), J26 (Early-Late Bajocian), J32 (latest Bajocian-Late Bathonian) and J34 (latest Bathonian-Middle Callovian). The tectono-stratigraphic units developed in response to large scale (second order) tectonic processes: pre-rift thermal uplift (J20) and the onset of rifting (J30), whilst sequence development was controlled by combination of changes in basin subsidence, sediment supply and eustatic sea level. A series of palaeogeographic and isopach maps outline the basin evolution and sedimentary response for each sequence. -from Authors
