C. Brousmichedelcambre et al., STRATIGRAPHICAL IMPLICATIONS OF THE REVISION OF THE CARBONIFEROUS FLORA SOUTH OF BRIANCON, Comptes rendus de l'Academie des sciences. Serie II. Mecanique, physique, chimie, astronomie, 320(4), 1995, pp. 335-340
The discovery of new fossiliferous localities has allowed a detailed r
evision of the Carboniferous flora along the Durance valley south of B
riancon. Contrary to all present interpretations, the recognized plant
assemblage in two areas gives no indication about the presence of Wes
tphalian B or C. It is indicative of a late Namurian B-Namurian C age
in Western Europe. However, an early Westphalian A age cannot be exclu
ded. Therefore, classically admitted stratigraphical subdivisions in B
rianconnais are no longer valid.
