Friday Field Foto #109: Yosemite granite

April 23, 2010

This week’s Friday Field Foto is from a weekend trip I took last month to Yosemite National Park. I’ve been trying to broaden my photo collection with more than just sedimentary rocks … so today is a close-up of some beautiful Yosemite granite. Now that I think about it, I’m assuming this is granite — if some igneous nerd wants to inform me that this is actually a granodiorite or whatever, please do!

    Looks like granodiorite or qtz-monzodiorite (K-feldspars < plagioclase feldspars).
    BTW, I am not really an igneous nerd :)

    It’s Granodiorite. I think. Actually I don’t know (even though am an ‘igneous “nerd”‘).
