Record #173122:

Palaeoproterozoic age of a basement gneiss complex in the Charcot Land tectonic window, East Greenland Caledonides / Kristine Thrane.

Title: Palaeoproterozoic age of a basement gneiss complex in the Charcot Land tectonic window, East Greenland Caledonides / Kristine Thrane.
Author(s): Thrane, Kristine.
Date: 2004.
In: Geological Survey of Denmark and Greenland Bulletin. (2004.), Vol. 6 (2004)
Abstract: Charcot Land tectonic window exposes crystalline basement gneisses, which form part of foreland of East Greenland Caledonides, previously believed to be Archaean. New U-Pb single-zircon ion microprobe analyses on gneisses of the window yield upper intercept ages of 1916 +/-21 and 1928 +/-11 Ma, interpreted to represent the age of crystallisation of igneous protolith. Foreland gneisses of Charcot Land window are of similar age to parts of allochthonous gneiss complexes of structurally overlying thrust sheets, but two terranes have different lithological and structural characteristics. No Archaean rocks have been positively identified in any East Greenland Caledonian foreland window.
