Western Java rain forests 2008

The metamorphic rocks were Cretaceous (100 m.y.) and Eocene (40 m.y.) ocean sediments that were folded between the Eocene and early Miocene Periods (20 m.y.).

Central Range montane rain forests 2008

It would fall into the 17 to 34 m.y. old category of central Nevada ash-flow tuffs (part of the Mid-Tertiary ignimbrite flare-up), and is probably in the 22 to 25 m.y. old range (that's my guess based on work in the region quite a while ago - the rocks haven't aged too much since then).
