  2. Boring Billion (Geological periods 🌍)

    The Boring Billion, otherwise known as the Mid-Proterozoic and Earth's Middle Ages, is an informal geological time period between 1.8 and 0.8 billion years ago during the middle Proterozoic eon spanning from the Statherian to the Tonian periods, characterized by more or less tectonic stability, climatic stasis and slo...

    [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…”

    "KEY POINTS
    • Basalts and pebbly to cobbly sandstones have been dredged from the Fairway Ridge, Coral Sea
    • Dating of the rocks and interpretation of magnetic anomalies allow mapping of major geological units across North Zealandia
    • This work completes offshore reconnaissance geological mapping of the entire 5 million square km Zealandia continent…”

  5. Terrestrial Oceans And Lunar Maria by G.F. Makarenko

    About the Book
    Both the Earth and the Moon have been repeatedly involved in episodes of volcanic activity induced by the heating of the interior of the two planets. Before the onset of each epoch of outpourings of lava that filled volcanic seas, arcuate and ring-shaped mountain chains encircled these seas in different regions of the planets.

    The Moon is a “simplified model” of the Earth. Reviewing the structures of the Earth and the Moon simultaneously, we shall better understand the origins and compositions of the mountain ranges of the Pacific coast and see why the Atlantic-type oceans are not surrounded by mountains, and what is common in the structure of the volcanic floor of terrestrial oceans and lunar maria.

    The book is intended for a wide circle of geologists, geographers, and astronomers and will also be of interest to those who are specializing in the geology of the Earth and the Moon.

    About the Author

    Galina Makarenko graduated from the Moscow Geological Exploration Institute named after Sergo Ordzhonikidse as an engineer-geologist. She is currently a member of the geological faculty at Moscow State University, where she conducts scientific research in the areas of geotectonics and volcanism. In addition to her research, she teaches general geology and trains both students and post-graduate students.
    For many years, Makarenko participated in scientific expeditions in regions of ancient volcanism, with her candidate thesis dedicated to the geology of these areas. Her expeditions to Kamchatka and the Kuril Islands focused on comparing ancient volcanoes with active ones. Her doctoral thesis is centered on the extensive sheets of volcanic rocks found on the Earth’s continents and oceans.

    She has published three monographs and numerous articles. Today, the author is actively engaged in collecting new data in the field of comparative planetology.

  7. The ground we live on is the top of a moving rock area that is really hot. The ground we live on is broken up into little rocks. Sometimes the little rocks move on top of each other. This makes the rocks get really tall. Sometimes one goes under the other one. The under rock gets really hot and becomes the moving rock under the ground. The moving rock under us sometimes comes up through the ground making new hot rock. [J. G.]

  8. Did you know that floors can move and dance? You can see it if you give it a chance. There are three ways the floor can move. The first is when two floors move close together. The second way the floor can move is when one floor is moving left and the other floor is moving right. This little dance can make points with hot red coming out. The final move a floor can do is rub close and shake, making a little dance for me, and you! [C.M.]
