The late Archaean mobile belt through Godthåbsfjord, southern West Greenland: a continent-continent collision zone? / Victor Raymond McGregor, C.R.L. Friend, Allen P. Nutman.
Title: | The late Archaean mobile belt through Godthåbsfjord, southern West Greenland: a continent-continent collision zone? / Victor Raymond McGregor, C.R.L. Friend, Allen P. Nutman. |
Author(s): | McGregor, Victor Raymond. Friend, C. R. L. Nutman, Allen P. |
Date: | 1991. |
In: | Geological Society of Denmark. Bulletin. (1991.), Vol. 39(3-4) (1991) |
Abstract: | In region, NE-SW-trending belt of rocks of very varied age and origin, here named Akulleq terrane, is separated by major faults from more extensive blocks of typical high-grade Archaean rocks that, although they are superficially similar, have different ages and metamorphic histories. Continental crust that forms block to NW was accreted c.2600 Ma, and block to SE c. 2900 Ma. It is suggested that Godthåbsfjord belt is result of collision of these blocks. Rocks of Akulleq terrane are interpreted as fragments of different parts of crust that separated blocks. |
