We present high spatial resolution ion-microprobe rare earth element (REE) data for discrete growth phases of complex polyphase zircons from early Archaean Amitsoq gneisses, outer Godthabsfjord, SW Greenland. In Matsuda diagrams, the two major growth phases, >3.8Ga cores and ca. 3.65Ga rims, have steep positive slopes from La to Lu, prominent positive Ce anomalies and negative Eu anomalies that...
Lithologically varied early Archaean rocks on the island of Akilia, Godthabsfjord, southwest Greenland include a quartz-pyroxene unit that has been proposed as a BIF. Carbon isotope data from graphite particles in apatites within this unit have further been proposed to represent evidence for Earth's earliest life. We present field observations which demonstrate that all lithologies on SW Akilia have...
