p.128: Bure Member (Gygi 1995) ; Previously "Humeralis-Mergel"). Member of the Vellerat Formation ; Synonymy: Gygi (2000b page 59) The Bure Member was renamed by Gygi (1995. p. 11 and Fig. 2). The name is derived from the village of Bure northwest of Porrentruy in Canton Jura (LK 1064 Montbéliard). Outcrops of this marly member are always artificial and temporary. A complete section of the member was provided by the exploration well BUR 2 for the Transjurane superhighway. The well was measured and published by Gygi (2000b. PI. 16) as section RG 454 at coordinates 567.649/254.670. LK 1065 Bonfol. This is the type section. The Bure Member is mainly a soft grey marl, but in some places like the type locality there are thin intercalations of limestone. The thickness is almost exactly 10 m at the type locality. The member contains neither ammonites (Gygi 1995, Fig. 2) nor dinoflagellates (Ghasemi et al.. 1999). It could only be dated by correlations with clay minerals (Gygi & Persoz 1986. PI. 1A, correlation 1) and sequence stratigraphy (Gygi et al. 1998. Fig. 2. sequence boundary O 7 The geographical range of the Bure Member externds over the northern Canton Jura (Ajoie region) and adjacent southern Alsace (France), see Fischer (1965. p. 19 and 58/59) and to the south to Glovelier. Canton Jura. Further south and to the east the member grades into the Oolithe rousse Member and ultimately into the Crenularis Member that can be dated with ammonites at the Bimammatum Subchron.
