Fig. 12. Conceptualised sequence structure and internal sedimentary architecture in the Halten Terrace Lower and Middle
Jurassic mixed, non-marine to shallow-marine megasequences (A). Conceptualised basin development and infill response
during the progradational segments (B) and the aggradational to retrogradational segments (C).
