Record #136847:

SHRIMP U-Pb single zircon geochronology of a Proterozoic mafic dyke, Isukasia, southern West Greenland / A.P. Nutman, H. Hagiya, S. Maruyama.

Title: SHRIMP U-Pb single zircon geochronology of a Proterozoic mafic dyke, Isukasia, southern West Greenland / A.P. Nutman, H. Hagiya, S. Maruyama.
Author(s): Nutman, A. P.
Hagiya, H.
Maruyama, S.
Date: 1995.
In: Geological Society of Denmark. Bulletin. (1995.), Vol. 42(1) (1995)
Abstract: Noritic dykes orientated north-south are early members of Proterozoic swarms which cut Archaean craton of West Greenland. Diffuse- margined felsic patch within wide dyke at Isukasia is interpreted to have crystallized at same time as rest of dyke. Three zircons were separated from 500 g sample of felsic patch. Pb isotopic ages were between 3390 and 3310 Ma.
