Outline of Final Research Achievements

We performed geological and geochemical works on the Saglek Block, northern Labrador, Canada to decode evolution of the early earth, and obtained some new discoveries as shown below. (1) We found the second oldest rock (3,950 Ma) on the earth, and named it Iqaluk gneiss. (2) The block is underlain by the Nulliak supracrustal rocks and the Iqaluk-Uivak Gneiss, which was intruded into the former; thus the formers are the oldest supracrustal rocks in the world. (3) The formers have imbricate (duplex) structure with ultramafic rocks, mafic rocks and sedimentary rocks in ascending order. (4) The structure and stratigraphy indicate that they are the oldest accretionary complexes, suggesting operation of plate tectonics. (5) Geochemistry of banded iron formation with positive La, Eu and Y anomalies indicates paleoseawater was enriched in Co, Zn and Ni. (6) We discovered organic matter with quite low δ13CPDB values, down to -29.8 ‰ in a clastic rock, providing the oldest trace of life.
