Late Glacial and Early Holocene human palaeogeography in the Mediterranean NE of Iberia

In the NE of the Iberian Peninsula the Late Glacial - Early Holocene period shows a cultural and demographic pattern with both abundance and absence moments. Microblade technologies start during GI-1 event breaking the absence of evidences during the glacial period. These technologies persist during the Late Glacial an Early Holocene converging in time with Sauveterrian and notches and denticulates Mesolithic technologies. The last two phases seems to appear together coinciding in time with the Pleistocene - Holocene boundary. The persistence of late Palaeolithic technologies breaks the homogeneity observed in the nearby territories. In this way particular occupational characteristics are observed in the cultural evolution of this zone of the Ebro basin and peninsular Mediterranean Levant.
