Fig. 8

Global palaeogeographic map for the Early Albian (105 Ma) after Blakey (2008) and including climate zones of Scotese (2000) and marine surface currents of Pucéat et al. (2005). Areas in black: continental mainlands and adjacent island arcs; thinly dashed lines: shelf break; arrows: marine surface currents; small dash-dotted lines delineations of climate zones; hatched zone: depositional area of the Helvetic; dotted lines potential source areas and implied driftways of the Werdenfels resin nodule, controlled by the Tethys Circumglobal Current. Possible source areas of the Werdenfels resin nodule: (1) East European mainland and islands with Agathoxylon pannonicum (Philippe et al. 2006); (2) Litoral area at the margin of the Ukrainian shield (Zherikhin and Eskov 1999); (3) Coastal region of an island which supplied the depositional area of the Nahr Umr Formation (Savkevich et al. 1990); (4) Levantine mainland with A. levantensis (Poinar et al. 2004); (5) Litoral area in Myanmar (Cruickshank and Ko 2003). Encircled areas show the approximate positions of deposits of the large igneous provinces: OJ Ontong-Java (125–120 Ma); K Kerguelen (118 Ma) (Larson and Erba 1999; Ogg et al. 2004)
