Published in three volumes in 1830–1833 by John Murray, the book established Lyell's credentials as an important geological theorist and popularized the doctrine of uniformitarianism (first suggested by James Hutton in Theory of the Earth published in 1795). The central argument in Principles was that "the present is the key to the past": that geological remains from the distant past co… WebbDarwin's Theory of Evolution is the structure that supports these efforts. Biostratigraphy is the science of dating rocks by the fossils they contain, and it was just getting started in Darwin's time. Scientists noticed that certain types of fossils appear in the same sequences everywhere in the geologic record.

WebbThe idea that the laws that govern geologic processes have not changed during Earth’s history was first expressed by Scottish geologist James Hutton, who in 1785 presented his ideas—later published in two volumes as Theory of the Earth (1795)—at meetings of the Royal Society of Edinburgh. WebbThe definition of a fractal distribution is that the number of objects N with a characteristic size greater than r scales with the relation N∼r −D. The frequency-size distributions for islands, earthquakes, fragments, ore deposits, and oil fields often satisfy this relation.
