Dating methods for quaternary deposits

18 Jun

This new find, recovered by modern methods and dated by molecular filtration and Hydroxyproline 14C, provides new information on the context and dating of Aurignacian graphic imagery in SW France and its relationship to that of other regions.

The support is not a fragment of collapsed shelter ceiling and is situated in the midst of quotidian occupational debris.

The pollen is extracted and then concentrated and stained and examined under a microscope.

; Ancient Greek: "cave deposit") — commonly known as a cave formations — are secondary mineral deposits formed in a cave.

In the excitement of the widely publicized new finds of Aurignacian art from Chauvet, from the Swabian Jura and from as far afield as Pestera Coliboaia in Romania, it has almost been forgotten that a rich corpus of Aurignacian wall painting, engraving and bas-relief sculpture had been recognized and studied before World War I in the Vézère Valley of SW France.

Scientific knowledge of the chronological and cultural context of that early-discovered graphic record has been limited by the crude archaeological methods of that pioneering era, and the loss and dispersal of many of the works discovered.

The examination of their production, dispersal, and applications is an aid to the reconstruction of past vegetation and climates and developing relative chronologies.

It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs.

The pollen grains of trees, shrubs, grasses, and flowers are preserved in either anaerobic conditions or in acid soils.

Samples can be taken from the deposits by means of a core or from individual layers at frequent intervals in a section face on an .

The image shows significant technical and thematic similarities to Chauvet that are reinforced by our reanalysis of engraved slabs from the older excavations at Blanchard.

The aligned punctuations find their counterparts at Chauvet, in the south German sites and on several other objects from Blanchard and surrounding Aurignacian sites.
