Abstract

The paper reviews briefly the various methods employed in the investigation of the nature of the deep continental crust. The methods include seismology, gravity, magnetism, heatflow, experimental petrology, isotope and trace element geochemistry, studies of "deep seated" inclusions.

The merits of the different methods are discussed, and it is concluded that a deep continental crust under shield areas of medium to high pressure granulite facies affinities is consistent with all existing data.
