💁🏻♀️ TIL: 🌋☄️ An analysis of 89 major geological events over 260 million years finds #Earth’s biggest disasters cluster every 27.5 million years.
An #NYU geologist suggests this may link interior processes to orbital cycles or the #solarsystem’s motion through the #MilkyWay. The idea remains controversial but has held up against refined #data.

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!

“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…”

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.”
~ Marie Tharp

Wilson Cycle Phase 3: Ocean Closing
“I enjoy, and have always enjoyed, disturbing scientists.”
~ John Tuzo Wilson
“From great oceans, giant mountains will form. This is the prediction of the third phase of the Wilson Cycle where we see the closure of the vast oceans like the Iapetus Ocean, and the formation of continent to continent collision mountains.”
~ Professor Dougal Jerrom, intro to Wilson Cycle Phase 3: Ocean Closing video linked below
In the 24 minute video below (a great watch), we continue our travels with Professor Dougal Jerrom of Oslo University, to look at evidence of the closing of the former Iapetus Sea in the Caledonian of Norway. The video starts with a nice recap of the other videos.
Whenever there is an ocean closure, geoscientists always look for ophiolite. Ophiolites in the geologic record provide evidence of subduction zone tectonics. We have already seen the pillow basalts, sheeted dikes (gabbros) and peridotites that form ocean crust in earlier videos in this series. An ophiolite is then a bit of oceanic crust that got swept up in the continental collisions and provides the first proof of an ocean closure.
Next we learn about melange - the sediments that were scraped up during subduction, also known as an accretionary wedge. There are also remnants of the island arc formed during subdution all accreted between the bits of continental crustal blocks that eventually collided.
Enjoy the video below where you see glimpses of the geology of the beautiful Norwegian Caledonian.

Refer to this great labeled diagram of the Wilson Cycle for the components of the ocean closure and continent to continent collision and mountain building: https://c.im/@vickyveritas/109628513962823739
Note: We will see the last steps of the Wilson Cycle, the continent to continent collision and the formation of giant mountain belts, and the great grand finale of this series. Stay tuned.

Wilson Cycle Phase 2: Ocean Opening
“…for times before the present oceans existed, we cannot do plate tectonics. Instead we must consider the life cycles of the ocean basins.”
~ John Tuzo Wilson
In the 12 minute video below (a great and quick watch), “Wilson Cycle Phase 2: Ocean Opening”, we continue our travels with Professor Dougal Jerrom of Oslo University, to look at evidence of the former presence of oceanic crust.
The first evidence we find is the presence of pillow basalts formed in the deep ocean. Pillow basalts are erupting magma that is quenched (hardened) by the ocean water. The scientists can tell that the ocean was deep because the pressure of the water allowed the gases to be released in solution (no vesicles in the basalt). Pillow basalts are the top layer of oceanic crust.
Secondly we find evidence of a black smoker in a copper mine. The black smoker was created by hydrothermal activity, as evidenced by the presence of copper and other minerals, in the sheeted dikes, the second layer of oceanic crust.
