So have I:


How are rock types dated?

* Rock types are not generally constrained to a specific time, eg granites occur throughout geo logical time. Igneous (eg granite, basalt and andesite) and metamorphic rocks (eg schists and gneisses) are dated predominantly by radioactive methods.

Sedimentary rocks are generally dated by the fossil they contain using zone fossils (those which have an internationally determined age range). All rocks can be dated relative to each other to give a local self-contained chronology, using what is called the "cross-cutting relationship" of one rock to another.

* Buy them a few drinks and enquire after their modelling aspirations.

I was right about that saddle
I made the mistake last year of involving the press on my cycling fundraising efforts, I was all over all the local rags. So embarrassing. I will not be sharing any links as I have asked google to un-index all the references and pages.

Well done Simon. I'm impressed.
