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!

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.

Wilson Cycle Phase 1: Rifting
“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…”
~ John Tuzo Wilson, “Did The Atlantic Close And Then Re-Open?” Nature, Vol. 211, No. 5050, August 13, 1966
Rifting of the enormously long mountain chain ended up with parts in both North America (Appalachians) and Norway (Caledonides), among many other places. Geologist and Geophysicist John Tuzo Wilson reconstructed the multi-phased tectonics to trace the earlier proto-Atlantic Ocean that closed, and today’s Atlantic Ocean that opened through the processes that are named for him: The Wilson Cycles.
In the video below, “Wilson Cycle Phase 1: Rifting”, we travel with Professor Dougal Jerrom of Oslo University, and researchers from the Centre for Earth Evolution and Dynamics (CEED) who take us back 450 million years, and into what was once 90 kilometers deep in the Earth’s crust to the Caledonian rocks of Norway that tell us about the biggest cycle on Earth. Don’t miss the video which gives a voice to the rocks that record our dynamic Earth and the Wilson Cycle.
