introductory book to the science of igneous petrology. Originally published in 1993; presents the thermodynamic basis for modern, quantitative petrology and systematically reviews metamorphism for most rock types. Popularly also known as the "big blue book". Petroleum geology Original work on seismic sequence stratigraphy. Plate tectonics First book to marshall considerable geological evidence that the continents are mobile relative to each other around the North Atlantic (mainly). It uses Evan Hopkins booklet (On the connection of geology with terrestrial magnetism, 1844), but adapts its data to a plutonist point-of-view. First book to show geological evidence that some continents were linked with each other: Suess set out his belief that across geologic time, the rise and fall of sea levels were mappable across the earth—that is, that the periods of ocean transgression and regression were correlateable from one continent to another. His theory was based upon glossopteris fern fossils occurring in South America, Africa, and India. His explanation was that the three lands were once connected in a supercontinent, which he named Gondwána-Land (nowadays usually written Gondwanaland). However Suess mistakenly believed that the oceans flooded the spaces currently between those lands. Moreover, Suess expressed views in this book on the connection between Africa and Europe. Eventually, he concluded that the Alps to the north were once at the bottom of an ocean, of which the Mediterranean was a remnant. Suess was not correct in his analysis, which was predicated upon the notion of "contractionism"—the idea that the Earth is cooling down and, therefore, contracting. Nevertheless, he is credited with postulating the earlier existence of the Tethys Ocean, which he named in 1893. Suess also introduced in this book the concept of the biosphere, which was later extended by Vladimir I. Vernadsky in 1926. Die Entstehung der Kontinente und Ozeane was the second book to marshall considerable geological evidence that the continents are mobile relative to each other on the surface of the Earth. His theory was based upon numerous matches between the topography, paleontology and past climate of continents now separated by oceans. At the time of publication his ideas were not taken seriously by most of the geological community as he could not provide a mechanism for continental motion, but his ideas form the foundations of the modern theory of plate tectonics. Summarized geological arguments for continental drift, with particular reference to Southern Africa and South America. It is considered
