Isopach map for the Early Jurassic rocks in N Switzerland, SE France and SW Germany (data sources as given in Table 1). Note that especially large uncertainties are attached to the thickness information from wells in the Molasse Basin and the Upper Rhinegraben (in particular for the determination of the Early to Middle Jurassic boundary, but also for the determination of the Early to Late Toarcian boundary; e.g., Pratje 1924; Théobald 1967; Lutz and Cleintuar 1999)
