McSween Harry Y., Huss Gary R. Cosmochemistry

Cambridge University Press. The Edinburgh Building, Cambridge CB2 8RU, UK. 2010. — 569 с.How did the Solar System's chemical composition evolve? This textbook provides the answers in the first interdisciplinary introduction to cosmochemistry. It makes this exciting and evolving field accessible to undergraduate and graduate students from a range of backgrounds, including geology, chemistry, astronomy and physics. The authors - two established leaders who have pioneered developments in the field - provide a complete background to cosmochemical processes and discoveries, enabling students outside geochemistry to understand and explore the Solar System's composition. Topics covered include: - synthesis of nuclides in stars - partitioning of elements between solids, liquids and gas in the solar nebula - overviews of the chemistry of extraterrestrial materials - isotopic tools used to investigate processes such as planet accretion and element fractionation - chronology of the early Solar System - geochemical exploration of planets Boxes provide basic definitions and mini-courses in mineralogy, organic chemistry, and other essential background information for students. Review questions and additional reading for each chapter encourage students to explore cosmochemistry further.

Космохимия, наука о химическом составе космических тел, законах распространённости и распределения химических элементов во Вселенной, процессах сочетания и миграции атомов при образовании космического вещества. Космохимия исследует преимущественно "холодные" процессы на уровне взаимодействий веществ, в то время как "горячими" ядерными процессами в космосе — плазменным состоянием вещества, нуклеогенезом (процессом образования элементов) внутри звезд и др. — в основном занимается физика.Introduction to cosmochemistryOverview
