Classic geochronology paper. U-Pb zircon emplacement age of the Baltoro granite = 21.0 +/- 0.5 Ma (early Miocene) with Precambrian inherited zircon; monazite dates 17-19 Ma. Used for Baltoro Granite Miocene emplacement age.

- Age: Tightened from "Miocene (25-12 Ma)" to an Early Miocene emplacement of 21.0 ± 0.5 Ma from U–Pb zircon dating (Parrish & Tirrul 1989), a late- to post-tectonic phase of the Karakoram batholith; monazite ages 17–19 Ma record slow post-emplacement cooling, and Precambrian zircon inheritance indicates a crustal-melt source.
