Complete hydrothermal re‐equilibration of zircon in the Maniitsoq structure, West Greenland: A 3001 Ma minimum age of impact?
Abstract Zircon in five samples of variably comminuted, melted, and hydrothermally altered orthogneiss from the Maniitsoq structure of southern West Greenland yield a weighted mean 207 Pb/ 206 Pb age of 3000.9 ± 1.9 Ma (ion probe data, n = 37). The age data constitute a rare example of pervasive and...
