Abstract

The length of this abstract is inversely proportional to my deep appreciation of Roberto and the opportunity to work with Roberto for so many decades. I will speak to his many contributions to important problems in and facets of the geosciences, including, but not limited to, the late Paleozoic/Mesozoic apparent polar wander path of North America, the magnetic polarity record of the late Paleozoic to late Triassic, redbed remagnetization, the tectonic history of northwest and southernmost (Chiapas) Mexico, and pluton emplacement in a lithosphere scale shear zone. I will never forget my many, many experiences with Roberto, the likely most notable one was in August/September, 1996, when field sampling of a Permian-Triassic boundary section in Xinjiang Province turned complicated, and we spent many days in "house arrest", becoming better and better friends, in Jimsar, some 250 km east of Urumqi, located on one of the ancient Silk Roads.
