Summary

The biggest part of W. Crete is structured by multiphase tectonic metamorphic rocks. Overtime, several researchers started describing the aggregate of these rocks or just part of them that are inserted between the cover of Tripoli and the para autochthonous “CreteManiunit” (Plattenkalk) / Group Plattenkalk and / or Tripali unit, with different nomenclatures. Therefore, the several given names to these tectonostratigraphic units that contain amounts of meta-basalt have fairly caused confusion concerning the scope of the term “phyllite-quarzite”. In Chania, within the “phyllite-quarzite” unit exist, apart fromdifferent outcrops, sites with residues of historic iron ore and copper mining activity.The purpose of this thesis is the identification and investigation of the distribution of the major minerals, mineralogical phases and minerals therein, and comparison of laboratory study results with older ones, through sampling in limonites, limonite crusts, iron ore deposits and outcrops of copper minerals from areas of W. Crete, within the “phyllitequarzite” unit. According to the data, an attempt is made, to understand the genetic origin and development of iron ore and copper ore deposits in the “phyllite-quarzite” unit of W.Crete and the comparison with the existing genetic models from earlier surveys.
