Abstract
To gain information about the geographical origin of oil samples, measureme nts of delta(13)C and delta(18)O of the whole oil and some of its fractions have been performed on samples coming from fruits of Olea europaea L. prod uced in Greece, Morocco, Spain, Italy, Tunisia, and Turkey. The results obt ained by applying statistical procedures have given pieces of evidence that oil samples have shown the trend to cluster according to the different cli matic areas of growing environment of fruits. Some confusion has been obser ved for samples coming from neighboring countries having similar climates.
