The Hurry Inlet granite and related rocks of Liverpool Land, East Greenland

Abstract

The Hurry Inlet granite, a late Lower Palaeozoic mass was emplaced into a basement complex which had been metamorphosed and deformed in an earlier period of plutonism. The host rocks were brittle at the time of emplacement and the granite made space for itself in part by stoping. Contacts are frequently faulted. Internal faulting is of a similar kind showing that the final movement was of a rigid granite mass which rose to a very high crustal level and was soon unroofed, the debris from unroofing being itself affected by similar faulting. The homogeneity of the mass is shown by petrography and chemistry and the chemistry indicates that it was generated at deep crustal levels.
