The Origin Of Continents And Ocean Basins by M. V. Muratov

Professor Mikhail Muratov, P.Sc., Corr. Mem. USSR Acad. Sci., is Head of the Chair of Regional Geology and Paleontology, Moscow Institute of Geological Prospecting. He is the winner of State and Lenin Prizes.

This book deals with the origin, structure, and tectonic behavior of the earth’s crust beneath continents and oceans and describes principal stages of the earth’s geologic history. The author attaches much importance to geosynclinal cycles and their role in continental crust build-up and discusses intri­guing hypotheses explaining the present day face of our planet.

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.

Found in the Midnight Zone: they're tiny, blobby, butt-shaped, and glow in the dark. What the heck are they? Scientists are still figuring them out.
