Ebook: Origin and Chemical Evolution of the Earth

In this book the author attempts to describe in popular form some problems of the Earth’s origin and its chemical changes over its long geological history on the basis of cosmochemical, geochemical and geophysical data obtained in recent years. The chemical evolution of the Earth is part of the chemical evolution of Space. Modern cosmochemical and geochemical data reveal that the chemical history of the Earth as well as of other bodies of the Solar System is associated not only with preserved stable and nonstable isotopes but also with extinct radioactive isotopes, including the isotopes of transuranium elements.
