1st Edition. BOUND FIRST EDITION (full volume) of the last of four papers by John Tuzo Wilson providing evidence to buttress the idea of both transform faults and the Vine-Matthews hypothesis that the sea floor is spreading, here arguing "how mutually supportive these two concepts were" (Frankel, The Continental Drift Controversy, 294). Reinforcing this, Wilson's paper points "out the existence of submarine fracture zones, which transversely cut the oceanic ridges - the transform faults - showed large-scale deformation of the oceans along these narrow mobile belts that form a network between the rigid plates offsetting the ocean ridges as a result of differential movement of the plates" (Valdiya, Aspects of Tectonics, 81). [Note that we offer a number of other Wilson papers separately as well as the Vine-Matthews paper]. Wilson's contributions to the theory of plate tectonics "introduced to the mainstream the idea that continents and oceans are in continuous motion over our planet's surface" and in so doing, revolutionized the ways we understand the Earth (Heron, Plate Tectonics, The Conversation, July 4, 2016). Scientific American counts Wilson's discoveries as one of the century's five major advances in science. In this paper, "Wilson thought about the mutual consequences of transform faults and aseismic ridges, and the generally inactive ridges that extended out from mid-ocean ridges and are occasionally topped by volcanic islands. Working from the idea that aseismic ridges are formed over hot spots, he proposed. that horizontal crustal motions relative to Earth's mantle are determinable by looking at the trends of island chains with the expectation that the age of islands along each chain increases with distance from its associated spreading ridge. He also claimed that the position of ridge-offsets relative to each other should be reflected both by the magnetic pattern and by the position of aseismic ridges on adjacent blocks between fracture zones. "Using these guidelines, he argue[s] [again in this paper, p. 910], that the â??floor of the Pacific is moving northwards like that of the Atlantic Ocean and several southern continents'. Returning to the issue of whether the great fracture zones are related to the East Pacific Rise or to the Darwin Rise, he argued that the fracture zones and aseismic ridges (Emperor Seamounts, Line Islands Ridge, Hawaiian Islands, Tuamotu Islands, Society and Ustral islands, Tehuantepec Ridge, Cocos Ridge, and Nazca Ridge) are associate with the East Pacific Rise. Given the close association of all these, excepting Hawaiian Islands, with the East Pacific Rise, he claimed that their westerly extension forms the western margin of the East Pacific Rise. He named this margin the ICSU Line in honor of the International Council of Scientific Unions. He imagined the western flank of the East Pacific Rise to extend at least to the middle of the Pacific Ocean. Then [p. 908], assuming that spreading rates had been the same on either flank of the East Pacific Rise, inferred that â??its eastern margin and northern crest' must â??have been overridden by the Americas' (Frankel, The Continental Drift Controversy, 294).

1st Edition. FIRST EDITION (full volume) OF JOHN TUZO WILSON'S 1965 GROUNDBREAKING INTRODUCTION OF THE CONCEPT OF THE TRANSFORM FAULT, THE PAPER THAT FOUNDED PLATE TECTONICS" (Dewey, Marking 50 Years of the Wilson Cycle, Geoscience Canada, 43, 2016, 283). "Whereas previous theories of continental drift had conceived of plates as either moving closer together (convergent plates) or further apart (divergent), Wilson asserted that a third kind of movement existed whereby plates slide past each other. This theory became one of the bases for plate tectonics, which revolutionized the geophysical sciences" (Encyclopedia Britannica). [Note that we offer other important Wilson papers separately]. Though Wilson wrote other papers of interest in 1962 and 1963, prior to 1965, he was "a staunch anti-drifter", meaning he didn't believe in continental drift. In 1965, Wilson began to tie "together many threads to create a cohesive paradigm that embraced continental drift, sea-floor spreading, subduction, and very large motions on transcurrent faults that defined the boundaries of and sites of relative motion between plates, the basis of what would come to be known as plate tectonics" (Dewey). His earlier work, even though anti-drifter, combined with his 1965 papers, "culminat[ed] in his definitive 1965 paper [this paper] that founded plate tectonics" (ibid). Wilson's 1966 paper, "Did the Atlantic Close and then Re-open" [which we offer separately], extended the possibility of continental drift before the break-up of the once supercontinent Pangea was likewise seminal. "One might fairly say that Tuzo's 1965 paper [this paper] changed the course of global tectonics and that his 1966 paper led to a complete new understanding of the implications of his 1965 paper for the origin of mountain belts resulting from super-continent cycles, the most important paradigm change in the history of geology" (ibid, 285). His contributions to the theory of plate tectonics "introduced to the mainstream the idea that continents and oceans are in continuous motion over our planet's surface" and in so doing, revolutionized the ways we understand the Earth (Heron, Plate Tectonics, The Conversation, July 4, 2016). Scientific American counts Wilson's discoveries as one of the century's five major advances in science. ALSO INCLUDED: Nobel Prize winner Joshua Lederberg's "Signs of Life: Criterion-System of Exobiology", pp. 9-13. In 1960s, Lederberg "introduced computer science and artificial intelligence to the biomedical laboratory" (NIH). He "started working with computers and quickly became tremendously interested in creating interactive computers to help him in his exobiology research. Specifically, he was interested in designing computing systems that to help him study alien organic compounds. [He] helped devise a system called Dendritic Algorithm (Dendral) that was able to generate possible chemical structures corresponding to the mass spectrometry data as an output" (Wikipedia). ALSO INCLUDED: K. Popper's "Time's Arrow and Entropy", pp. 233-234. Popper "attacks the significance of irreversible thermodynamic processes. He claims that with very few and short-lived exceptions, the entropy in almost all known regions (of sufficient size) of our universe either remains constant or decreases, although energy is dissipated (by escaping from the system in question)" (Esfield, Popper on Irreversibility and the Arrow of Time, 4).

[++] Two important papers supporting the idea of Continental Drift. [++] These are two very significant and pioneering efforts in the history of Continental Drift. "The Canadian geophysicist John Tuzo-Wilson [CC OBE FRS FRSE FRSC (1908 1993)] was initially skeptical of the theory of Plate Tectonics, but eventually became one of its most famous supporters, proposing two important ideas. While evidence for Continental Drift was mounting, the theory still hadn't explained why active volcanoes are found many thousands of kilometres from the nearest plate boundary. In 1963, Tuzo Wilson proposed that plates might move over fixed 'hotspots' in the mantle, forming volcanic island chains like Hawaii. In 1965, he followed this discovery with the idea of a third type of plate boundary - transform faults. Also known as a conservative plate boundaries, these faults slip horizontally, connecting oceanic ridges (divergent boundaries) to ocean trenches (convergent boundaries) Transform faults were regarded as the missing piece in the puzzle of plate tectonic theory. They allowed for plates to slide past each other without any oceanic crust being created or destroyed. The most famous example is probably the San Andreas Fault between the North American and Pacific plates."-- Geological Society (website), "Pioneers of Plate Tectonics". In his career Wilson received the Wollaston Medal, Penrose Medal, and the John J. Carty Award for the Advancement of Science.

Hardcover. First edition. THE TECTONIC CYCLE. First edition, very rare offprint, of this landmark paper elucidating the history and mechanism of continental drift by "one of the most imaginative Earth scientists of his generation" (DSB). "In 1966, J. Tuzo Wilson published 'Did the Atlantic Close and then Re-Open?' in the journal Nature. The Canadian author introduced to the mainstream the idea that continents and oceans are in continuous motion over our planet's surface. Known as plate tectonics, the theory describes the large-scale motion of the outer layer of the Earth. It explains tectonic activity (things like earthquakes and the building of mountain ranges) at the edges of continental landmasses (for instance, the San Andreas Fault in California and the Andes in South America)" (Heron). Alfred Wegener (1880-1930) had already suggested in the early 1900s that continents move around the surface of the earth, specifically that there had been a super-continent (Pangaea) where now there is a great ocean (the Atlantic). In the present paper, Wilson explained the geological evidence that North America and Europe were once separated across an ocean before the Atlantic Ocean. This ocean closed in stages as the continents that used to be separated by the ocean converged by subduction and eventually collided in a mountain-building event. The combined continent was then sliced apart and the continents drawn away from each other once more as the modern Atlantic Ocean opened. The paper combined the nascent ideas of divergent and convergent plate boundaries into a conceptual model that matched observations of geological features around the world. The tectonic cycle he described now goes by 'the Wilson Cycle' or the 'Supercontinent Cycle' and still governs how we think of the evolution of tectonic plates through time. "Wilson's great idea was a crucial step forward. It reopened the whole question of 'what happened before Pangea?' By suggesting that his 'proto-Atlantic' had opened within an earlier supercontinent (just as the Atlantic did within Pangea) he also linked his process to a grander cycle leading from one supercontinent Earth to another" (Nield). As was often the case for offprints from Nature (e.g., the famous Watson/Crick DNA offprint), this offprint is printed in a smaller format than the journal issue, with the text reset. No copies in auction records or on OCLC. In the early twentieth century the prevailing wisdom regarding how mountain belts were formed and why the sea is deep was that the Earth started out as a molten ball and gradually cooled. When it cooled, heavier metals such as iron sank down and formed the core, while lighter metals such as aluminium stayed up in the crust. The cooling also caused contraction and the pressure produced by contraction caused some parts of the crust to buckle upwards, forming mountains, while other parts of the crust buckled downwards, creating ocean basins. "Originally a devotee of the contracting-Earth hypothesis, [Tuzo Wilson] became a convert to [continental] drift as he was entering his fifties (by which time he had been Professor of Geophysics at Toronto for a decade). Swiftly recanting his former views, Tuzo saw the way the Earth's mountain belts were often superimposed upon one another, and set about explaining it in terms of plate tectonics. In a classic paper published in Nature in 1966 and titled 'Did the Atlantic close and then reopen?' he addressed the coincidence of the modern Atlantic with two mountain ranges called the Caledonides in Europe and the Appalachians in the USA. It was the very first time the new plate tectonics had been extended back to the pre-Pangean Earth. "These two mountain ranges are really one and the same - except that they are now separated by the Atlantic Ocean, which cut the range in two at a low angle when it opened between them. At one time the two belts had been joined, end-to-end, Caledonides in the north, Appalachians in the south; and the collision that had created them was one event among many that built the supercontinent Pangea. Indeed, the matching of the now separated halves of this once-mighty chain provided Wegener with one of his key 'proofs' - part of his geological matching of opposing Atlantic shores . "Wegener did not speculate about how his Pangea had come together. But as the new plate tectonics emerged from studies of the ocean floor and began to revitalize drift theory, the time was ripe to see the break-up of Pangea as part of a bigger process. Professor Kevin Burke of the University of Houston, Texas, recalls that on 12 April 1968 in Philadelphia, at a meeting titled 'Gonwanaland Revisited' at the Philadelphia Academy of Sciences, Wilson told his audience how a map of the world showed you oceans opening in some places and closing in others. Burke recalls: 'He therefore suggested that, because the ocean basins make up the largest areas on the Earth's surface, it would be appropriate to interpret Earth history in terms of the life cycles of the opening and closing of the ocean basins . In effect he said: for times before the present oceans existed, we cannot do plate tectonics. Instead we must consider the life cycles of the ocean basins.' This key insight had by then already provided Wilson with the answer to an abiding puzzle in the rocks from either side of the modern Atlantic. "Nothing pleased Tuzo more than a grand, overarching framework that made sense of those awkward facts that get thrown aside because they don't fit - ideas that philosopher William James dubbed the 'unclassified residuum.' Geologists had been aware since 1889 that within the rocks forming the Caledonian and Appalachian mountains - that is, rocks dating from the early Cambrian to about the middle Ordovician (from 542 to 470 million years ago) - were fossils that fell into two clearly different groups or 'assemblages.' This was especially true for fossils of those animals that in life never travelled far, but lived fixed to, or grubbing a.
