Walk up through Annot town section (viewing La Coste section on the way up) to Les Scaffarels (1000 ft elevation higher); detailed observations within some of the very thick (10’s m) sandstone packets of so-called "massive [structureless] sands", pebbly sands, scour and fill, cross-stratification, dish structures etc. Walk horizontally through sand bodies viewing thin-bedded turbidites (permeability barrier) between major sand-rich packets to Chambre du Roi.  Close-up view of the large erosional surface at Les Scaffarels.  Internal heterogeneity of sediment packages, etc.

Group Evening meal.  Short evening presentations.

Day 3 - Montagne de Chalufy

Stop 4 – Chalufy Mountain.

Spectacular seismic-scale onlap of sand-rich packets onto Marnes Bleues Formation; discussion of seismic expression of onlap (differences and similarities compared with salt province of Gulf of Mexico etc.); discussion of link with Annot Town section ~12km south-southeast and early basin-floor topography trapping older sands within Annot “sub-basin”; discussion of fill-and-spill concept of basins applied to SE France; discussion of fan systems in other sub-basins within Haute Provence (proximal-distal and axial-lateral changes).  Sandstone-filled channel-like feature showing both margins laterally to margin.  This walk will be most of the day and is an elevation change of 2000 ft uphill for about 1.5 hours.

Packed Lunch

Stop 5 – Annot road section.

Roadside section in thick, massive sands of the Annot sub-basin.  Discussion about sediment transport/deposition processes.

Group Evening meal.

Day 4 - Peïra Cava area

Stop 6a - Peïra Cava overlook.

Seismic-scale views of deep-marine system showing lateral high-continuity of many sandstone beds and packets in Cimes de Sourcas.  Introduction to Peïra Cava sub-basin.

Lunch: Peïra Cava

Stop 6b - Peïra Cava log A.

Detailed sedimentary logging (in groups of 3-4) of a few tens of meters of section along road cuts (Log A of Pickering & Hilton, 1998); discussion of sedimentary processes leading to deposition of very thick (genetically linked) sandy beds; evidence for decelerating and accelerating turbidity currents, interaction with basin-floor topography, flow-stripping, sediment slide/debris flow units, high versus low-concentration turbidity currents, competence versus capacity of flows; discussion of evidence for by-pass versus sediment accumulation.

Stop 7 - Peïra Cava log A.

Road outcrops of Log B; comparison with Log A (Proximal-distal versus axial-lateral relationships within Peïra Cava sub-basin; comparison between western and eastern basin-floor systems; discussion of relevance of Paleogene of SE France to areas of current interest to participants on course.
