  1. 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!

  2. 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…”

  4. Earth's internal heat budget (Earth 🌍)

    Earth's internal heat budget is fundamental to the thermal history of the Earth. The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantl...

    “HIGHLIGHTS:
    • Earth may have had a ring during the middle Ordovician, from ca. 466 Ma.
    • Breakup of an asteroid passing within Earth's Roche limit likely formed the ring.
    • Among several features preserved is a near-equatorial band of impact craters.
    • Shading of Earth by the ring may have triggered a global icehouse period…”

  6. Plate tectonics, the process that shapes Earth’s surface, was surprisingly speedy in the past, a new study reveals. The study measured the speed of plate movements over the last two billion years and found that they were much faster than today, reaching up to 20 centimeters per year. Plate tectonics may have started earlier than previously thought, and that it may have influenced the evolution of life and climate.
