On the ophiolites and the concealed magnetic bodies of the island of Crete (Greece)

Ophiolitic outcrops are present all over the central and eastern part of the island of Crete (Greece). They constitute the uppermost tectonic nappe and cause discernible magnetic anomalies of wavelengths between 4 and 15 km. Anomalies of the same wavelength are also present either in the vicinity of the outcrops or at remote places. The bodies that cause these anomalies are modelled and some considerations on whether they are caused by intrusions or by ophiolitic bodies, are expressed. Depth estimates, inversion and modelling are performed on the dominant anomaly of the magnetic map which is considerably larger than any other presence of a deep (1 km beneath sea-level) body is suggested which lies under the older nappe present on the island.
