Description of the Peneiada Valley Project-1 Borehole

A dedicated subproject was set up within the framework of the major PMZ project in order to define more accurately the stratigraphy of the sedimentary succession infilling the Peneiada Valley and especially to chronologically constrain the palaeogeographic evolution of the broader area around the tell during the 6th to 2nd millennia BC. In order to achieve these goals, a borehole has been drilled for obtaining a continuous core of the latest Quaternary alluvial deposits. In particular, the target was twofold: firstly, a detailed analysis of the sedimentary log for distinguishing and characterising the superposed depositional (i.e. environmental) facies and their vertical variations; secondly, the core would have provided samples to be analysed with the radiocarbon technique for obtaining calibrated ages at different depths.
