Abstract
Drăguşanu and Tanaka (1999) provide intriguing new chemical and isotopic analyses of amphibolites and gneisses from the Cumpăna Group, the oldest lithostratigraphic unit in the Getic‐Supragetic unit of the South Carpathians (Balintoni 1975; Pana 1994). Ten amphibolite whole‐rock data points form a linear trend in a plot of measured ^(143)Nd/^(144)Nd against ^(147)Sm/^(144)Nd (Drăguşanu and Tanaka 1999, fig. 3). Drăguşanu and Tanaka interpreted this as a 1.57‐Ga isochron. This age corresponds to the oldest determined magmatism in the south Carpathians and, if true, would be instrumental in elucidating the tectonomagmatic evolution of the Carpathian basement, which is obscured by younger orogenic cycles such as the Hercynian (Variscan) and the Alpine.
