Charnockite at Swift Run Gap

Over the weekend, I ran a 1-credit field course for NOVA, on the geology of Shenandoah National Park. I was about eight minutes early getting to the meet-up location, so that allowed me to check out a promising new outcrop of rock along the road (route 33, ~100 m west of Swift Run Gap). Here are two photos of it: charnockite (pyroxene-bearing granitoid or meta-granitoid), with weak foliation:

This is what my free-time geologizing has been reduced to: squeezed in to a few spare minutes here, a few spare minutes next week. No time for any more than that…

  1. Hi Callan,
    Recently I have attempted to access yr old Nova Geoblog to refer to some old materials that you have posted but it has been closed. Please let me know whether you can allow me to refer back to those old posts around end of 2009, I will find out the “title” of the particular post I need.
    Thank you.

    • They are all still there – it’s just that you have to have “www” in the URL, whereas a Google search will just return a “http://nvcc.edu…” address.
