Earth, Sweet Earth ( Science For Everyone) by Ekaterina Radkevich
The book is based on the author’s impressions of her numerous expeditions in the many countries. It is a fascinating narrative rather than a mere record of facts irrespective of how scientifically valid they can be. The book is bound to be appreciated as a piece of absorbing reading by anyone who cares to increase the scope of his or her competence about our sweet home of a planet that must be saved from destruction at all costs.
Ekaterina Radkevich, Corresponding Member of the USSR Academy of Sciences, is one of the most distinguished geologists whose works are well known in her own country and in many other parts of the world. The overwhelming success of her publications is chiefly due to her indefatigable practical activity in the USSR and elsewhere and her unflagging interest in theoretical research which she has been conducting for quite some time at the Institute of Geological Studies in the Far East (Viadivostok).
Note: This book was the last remaining volume in the Science for Everyone Series! This completes volume the SFE series in English.
Many, many thanks to Hassaan Ali who purchased and posted this book to us to complete this series. Much appreciated help!

Late Miocene Euphrates River Drained Into A Partially Desiccated Eastern Mediterranean

[the paleogeographic reconstruction is outstanding, including the strength and information conveyed so well in that figure, kudos!]
H/T @lina Jakaitė-Darkšė
“Although the Euphrates River - stretching ~3,000 km across Western Asia - has shaped the region’s geology for millions of years, the timing of its origin and the evolution of its course remain enigmatic. So far, two contrasting hypotheses have been proposed to explain the fluvial system’s Late Neogene path: termination in Anatolia at a palaeo-lake or the Mediterranean, or a southeastward continuation to Arabia. Here [they] use seismic-reflection and topographic data to show that two previously identified sedimentary accumulations - deposited during the terminal phase of the Late Miocene Messinian salinity crisis - resulted from dual riverine systems that drained into a partially desiccated eastern Mediterranean before avulsing toward the Persian Gulf and converging to form the modern Euphrates River. From probabilistic sediment-budget modelling, [they] show that although the latest Messinian drainage basins were an order of magnitude smaller than their present-day extents, the total palaeo-discharge exceeded that of the modern Tigris, Euphrates and Nile rivers combined, indicating intense palaeo-precipitation and high palaeo-relief. These results suggest that plate-margin deformation both controlled the fluvial avulsions that diverted the Euphrates River from the Anatolian–Eurasian Plate to the Arabian Plate, and established the conditions necessary for the development of the alluvial Fertile Crescent…”

The history of cartography is littered with such pseudo-continents, chimerical islands, dream-rivers and other Wilkean visions, flickering between the literal and the mythical. cartographers have often tended also to be dreamers, seduced into their science by the beauty of maps and the flights of imagination that they prompt.
~ Robert Macfarlane, Mountains of the Mind
Imagine now the flight of the imagination that took place when geologist and cartographer Marie Tharp connected the pattern of canyons, ridges, and mountains she was mapping, along with the pattern of earthquakes in those regions, to the burgeoning theory of plate tectonics and seafloor spreading. A single map can change the world.
“Not too many people can say this about their lives: The whole world was spread out before me (or at least, the seventy percent of it covered by oceans). I had a blank canvas to fill with extraordinary possibilities, a fascinating jigsaw puzzle to piece together: mapping the world’s vast hidden seafloor. It was a once-in-a-lifetime—a once-in-the-history-of-the-world—opportunity for anyone, but especially for a woman in the 1940s. The nature of the times, the state of the science, and events large and small, logical and illogical, combined to make it all happen.”

On January 14, 1890, British geologist Arthur Holmes was born. Holmes pioneered the use of radiometric dating of minerals and was the first earth scientist to grasp the mechanical and thermal implications of mantle convection, which led eventually to the acceptance of plate tectonics.
