Radiocarbon age and depth: a statistical treatment of two sequences of dates from Spain

Two sets of radiocarbon determinations from closely related sites in Valencia procince, Spain, show an increase of age with depth. We explore a model of uniform sedimentation to show this relationship and interpolate the ages of certain cultural events. A weighted least squares regression allows us to consider the variations in both parameters. Testing of this model shows no significant difference from linearity. We suggest some ages for particular cultural events in Valencia province which now need independent confirmation.
