This inference is based on the U-Pb age of24.0 :t 0.4 and 21.9 + 0.2 Ma for the
zircon from the Makalu granite (Scharer, I984) for which the earlier reported Rb/
Sr isochron age is 92.7 :1: 9.4 Ma (Kai, 1981) and the strong feeling of these ...

(b) Granites: Granite massifs are of local occurrence and, in the absence of
volcanism, they constitute a major element in favour of a recent geodynamic
evolution of the Hymalaya (Le Fort, 1973, Le Fort et al., 1978). Granite massifs
are found ...
