摘要

The old global tectonics of James Dwight Dana was one of America's first major contributions to theoretical geology. That theory began with Dana's experiences in the Pacific on the Wilkes Exploring Expedition (1838-1842), which paralleled closely the experi- ences of Charles Darwin a few years earlier. He refined Darwin's hypothesis of oceanic subsidence in 1843 by adding geomorphic evi- dence of subsidence, differential crustal responses, and variable island ages, and went on to develop a comprehensive global theory during the remainder of his life.
