S. Warren Carey rejects the concept of subduction. In this book he links together four subequal themes, with a few autobiographical notes sprinkled throughout, listed as follows in order of decreasing length: a history of science, a lucid review of tectonics and structural geology, an updating of his hypothesis that the Earth is expanding, and a review of the frontiers of cosmology, leading finally to a suggested mechanism for the expansion. Tectonics and structural geology have served as the hub of Carey's long and wide-ranging career, and the history of science section of this book emphasizes geology and geophysics, with special reference to the tribulations of scientists like Sam Carey himself, who marched to a different drummer and bucked the establishment.
Carey began his career, his dissertation work, in New Guinea, site of the world's most vigorous shearing (some would say transpression) between the Australia-India and the Pacific “polygons” (Carey uses that term to distinguish his 2900-km-thick tectonic blocks that move on the liquid outer core of the Earth from the 100-km-thick plates of plate tectonic theory). He immediately became a mobilist, and for the next 20 years, along with a few other geologists of vision, had to grapple with a fixist establishment.
