To gain information about the geographical origin of oil samples, measurements of 
13C and 18Oof the whole oil and some of its fractions have been performed on samples coming from fruits ofOlea europaea L. produced in Greece, Morocco, Spain, Italy, Tunisia, and Turkey. The resultsobtained by applying statistical procedures have given pieces of evidence that oil samples haveshown the trend to cluster according to the different climatic areas of growing environment of fruits.Some confusion has been observed for samples coming from neighboring countries having similarclimates.Keywords: Carbon and oxygen stable isotopes; olive oil; geographical origin
