Geologists who have grown up on shield rock-Precambrian craton-tend to be interested in copper, diamonds, iron, and gold. Most of the world’s large metal deposits are Precambrian. Diamonds, after starting upward from the mantle, seem to need the thickness of a craton to survive their journey to tl1e surface world. Geologists who grow up in California start out with strange complex structures, highly deformed rock-melanges and turbidites that seem less in zakelijke energie vergelijken need of a G. K. Gilbert than of an Alfred Adler or a Carl Jung. Shell, in its rosters, used to put an asterisk beside the names of geologists from California. The asterisk meant that while they were in, say, Texas they might be quite useful among the Gulf Coast turbidites of the Hackberry Embayment, but assign them with caution almost anywhere else. A former Shell geologist (not David Love) once said to me, “The asterisk also meant ‘Ship them back to California when they’re done.’ Shell considered them a separate race.” A geologist who grew up in Wyoming would have something of everything above-with the probable exception of the asterisk. A geologist who grew up in Wyoming could not ignore economic geology, could not ignore vertebrate paleontology, could not ignore the narrative details in any chapter of time (every period in the history of the world was represented in Wyoming). Wyoming geology would above all tend to produce a zakelijke energie generalist, with an eye that had seen a lot of rocks, and a four-dimensional gift for fitting them together and arriving at the substance of their story-a scenarist and lithographer of what geologists like to call the Big Picture.
