Friday Rock Blogging: Granite
PZ Myers was right to call for a more inclusive vision of Friday Cat Blogging, noting that 99% of the species on the planet are non-chordates while the Friday Ark continues to be dominated by a small number of mammalian genera. Sadly, his progressive vision of a non-phylist Friday is still stuck within the dominant lifeist framework. Chris Clarke’s Friday Fossil Blogging is a step in the right direction, however, True Justice demands Friday Rock Blogging! And we are not ones to resist the call of True Justice.
Courtesy the USGS photo library (which is, incidentally, in the public doman, so hoorah!) comes this picture of a chunk of granite from the Precambrian St. Francis Mountains, Missouri. Note the adorable potassium feldspar matrix! Awww.
