Abstract
Decompacted isopach maps were drawn up for the five members of Lens Fo rmation (upper part of early Kimmeridgian and late Kimmeridgian). Seve ral depocentres separated by high areas are distinguished. They are st riking E-W in the northern part of the Aquitaine basin, while in the s outhern part they are shaped by a rhombic fault framework (NNW-SSE and WNW-ESE). Depocentres and fault organization suggest a submeridian sy nsedimentary stretching.
