Daily run: 7.6 km, along
this route. Flies were so bad, we cut our run short by 0.5 km.
Heard a fairly interesting talk today about selenium and VMS deposits. Interesting
to me, having nearly no experience with actual geochemical research. I found it
refreshing to see a scientist compare
in situ geologic formations/deposits with
modern, active depositions which, theoretically, will become similar to current deposits
of economic value. He looked at hydrothermal vents on the ocean floor, both off the
coast of Chile, near Easter Island ("purely" magmatic origin), and in the Gulf of California (combination of magmatic origin and lots of sediments).
