Instead of the ruling hypothesis, condensation from a hot nebular cloud, gravitational accretion of cold objects (plan- etesimals) was proposed. Once formed, Earth was subjected to continuing, but spasmodic, radial gravitational contraction, which had overtones of isostasy. Chamberlin postulated that contractional events caused mountain building due to differential vertical movements of radial earth segments. Another byproduct of the theory was a diastrophic control of global sea level and erosional leveling of continents. This had wide impact upon American stratigraphy and geomorphology; it even anticipated modern sequence stratigraphy. Chamberlin’s commitment to vertical tectonics made him an inevitable oppo- nent of continental drift. In 1899, Chamberlin challenged famous physicist Lord Kelvin’s calculation of an age for Earth of only 20–30 million years when geologists were thinking of 100 million. Chamberlin dis- puted Kelvin’s assumption of simple cooling from a molten origin because he was already formulating his own cold, planetesimal origin. He argued that there must be some unknown source of heat energy within Earth that would alter Kelvin’s calculations substantially. Without realizing it, Chamberlin had anticipated heat from radioactive decay, which had just been recognized but was not yet widely understood.

Chamberlin was born on that moraine in southeastern Illi- nois, but his family moved north to settle near Beloit in southern Wisconsin. Young Chamberlin helped his father, a Meth- Thomas Chrowder Chamberlin odist circuit minister and farmer, and four brothers haul lime- stone slabs to build their farmhouse.

Moral rectitude characterized his research program. He also founded the Journal of Geology and entire career; he even viewed science as a moral activity. Rec- titude also could make him very aggressive when challenged by others. Because of his vigorous attacks upon the views and motives of his adversaries, his USGS appointment was ter- minated in 1904. Although his “Method of multiple working hypotheses” seemed the ideal recommendation for reasoning in a complex science with limited available evidence so as to maintain objectivity, he did not always practice what he preached. The longer he worked on his planetesimal hypothesis, the more dogmatic he became, excluding all competing hypotheses from consideration so that it became just the kind of ruling hypothesis that he had railed against in 1890. The great T.C. Chamberlin was human after all.

AGI Medal in Memory of Ian Campbell The Ian Campbell Medal is given in recognition of singular performance in and contribution to the profession of geology. Candidates are measured against the distinguished career of Ian Campbell, whose service to the profession touched virtually every facet of the geosciences. Campbell was a most uncommon man of remarkable accomplishment and widespread influence. In his career as a geologist, educator, administrator, and public servant, he was noted for his candor and integrity. To make a nomination, please go to www.agiweb.org/direct/awards.html.

GSA TODAY, October 2006 39 disagreement was related to whether the mechanism of recycling lithosphere into the mantle evolved as Earth cooled. One PENROSE CONFERENCE way to partially bypass this issue is to consider “modern-style” subduction (steep slab subduction) and “premodern-style” subduction, which may have been different (e.g., symmetric Report lithosphere foundering, flat subduction, or eclogite-driven When Did Plate Tectonics Begin? delamination of oceanic or lower continental crust). Although geodynamic models support the existence of coherent lithospheric plates throughout earth history, just 14–18 June 2006 when and how these plates became negatively buoyant is not Lander, Wyoming, USA yet clear. This is partly due to our uncertainty about the early thermal history of the mantle. Most participants agreed that the Conveners: Archean mantle must have been hotter, but it is not clear how much hotter. A closely related and unsolved question asks how Kent C.

Although it is com- Science, New Mexico Tech, Socorro, New Mexico 87801, USA, monly thought to have been thicker than now, thus making [email protected] Archean plates more buoyant, Geoff Davies presented a model whereby the early oceanic crust may have been no thicker than Alfred Kröner, Institut für Geowissenschaften, Universität at present if the upper mantle was strongly depleted.

Although other alternatives to plate tectonics in thermal regimes (low-P–high-T and high-P–low-T) suggestive the Archean were considered (such as mantle plume tectonics of plate tectonics are identified at least to 2.8 Ga and possibly and “drip” tectonics, whereby drips of hot oceanic lithosphere to 3.3 Ga.

One participant favored not become common in the geologic record until after 1 Ga, the idea that “modern-style” plate tectonics began about suggesting to Bob Stern that “modern-style” plate tectonics 1 Ga. Regardless of the fact that a consensus was not reached, did not begin until about 1 Ga. However, as pointed out by most of the evidence at hand suggested that “modern-style” John Percival, more efficient subduction in the Archean may plate tectonics “evolved” from an earlier form of proto–plate have prevented blueschists and UHP metamorphic rocks from tectonics sometime in the Archean. The group did agree that returning to the surface. Another possibility is that subduction answering the question of when plate tectonics began is critical geotherms may have been too steep in the Archean to pass for understanding the evolution of the solid earth system, and through the blueschist stability field, although the relationship participants appeared to leave the meeting rejuvenated and of mantle temperature to subduction geotherms is not well challenged by a greater appreciation of the multidisciplinary understood. Although complete ophiolites older than 2 Ga nature of the question as well as the many other questions that have not been found and are rare before 1 Ga, many Archean remain unanswered. greenstones may represent fragments of upper oceanic crust, as in the section we examined on our second field trip to the Participants Tin Cup Mountain area in central Wyoming.
