Chapter 1Helium and Argon Isotopes

Khalenev, Vladimir; Prasolov, Edward; Gruzdov, Konstantin; Zavilejsky, Dmitry; Lokhov, Kirill; Prilepsky, Edward; Badinova, Vera

Pages: 1 –47

[The results of helium and argon isotope composition measurements (3He/4He, 40Ar/36Ar ratios and others) are presented in the chapter. In paleofluids from the Norilsk intrusions, the crustal helium is dominant, and the fraction of mantle helium is in the range from 0.1 to 22%. The contribution of...

Chapter 2Sulphur Isotopes

Prasolov, Edward; Khalenev, Vladimir; Belyatsky, Boris; Prilepsky, Edward; Nazarova, Tatiana

Pages: 49 –72

[The chapter presents the results of sulphur isotope composition measurements (δ34S, in ‰), which showed that in rich intrusions sulphur is in most cases isotopically heavy (δ34S = 9–13, average about 11‰), and in this parameter corresponds to the crustal source, apparently, in most cases,...

Chapter 3Copper and Nickel Isotopes

Sergeev, Sergey; Kapitonov, Igor; Krymsky, Robert; Sergeev, Dmitriy; Adamskaya, Elena; Goltsin, Nikolay

Pages: 73 –88

[The chapter describes a technique of analysing copper and nickel isotopes in ores and magmatic rocks of deposits. Average δ65Cu value strongly diverges in rich intrusions: Kharaelakh (−1.55‰), Talnakh (−0.7‰), and Norilsk-1 (+0.25‰). Perhaps this is due to the mixing of the crustal and mantle...

Chapter 4Strontium and Neodymium Isotopes

Bogomolov, Yevgeny; Belyatsky, Boris; Krymsky, Robert; Pushkarev, Yury

Pages: 89 –132

[The chapter presents data on Rb–Sr and Sm–Nd TIMS analysis of pyroxenes, plagioclases, gross samples of igneous rocks and sulphide ores. In most Sm–Nd analyses of minerals, the isotope system (pyroxene–plagioclase) does not reflect the age of intrusions and shows a rejuvenated or aged...

Chapter 5Lead Isotopes

Belyatsky, Boris; Pushkarev, Yury; Prasolov, Edward; Kapitonov, Igor; Krymsky, Robert; Sergeev, Sergey

Pages: 133 –187

[The discussed below results on Pb isotopic compositions have been obtained by both TIMS and LA-ICP-MS-MC techniques on sulphide and plagioclase mg-weight specimens and single grains correspondingly. General Pb isotopic compositions imply derivation from both, the mantle and crustal sources with...

Chapter 6Lutetium and Hafnium Isotopes in Zircons

Kapitonov, Igor; Lokhov, Kirill; Sergeev, Dmitriy; Adamskaya, Elena; Goltsin, Nikolay; Sergeev, Sergey

Pages: 189 –205

[Lu–Hf isotope is an informative geochemical tool. Comprehensive in situ study of U–Pb and Lu–Hf isotope systems in zirconium minerals (zircon, baddeleyite) by LA-ICP-MS allows obtaining characteristics of the initial substance and evolution of the earth’s crust. The data bear the crucial...

Chapter 7Isotope Correlations in Rocks and Ores of Major Intrusions in the Norilsk District

Petrov, Oleg; Prasolov, Edward; Sergeev, Sergey; Pushkarev, Yury

Pages: 207 –213

[He, Ar, S, and Cu isotope characteristics of the Norilsk-1, Talnakh, and Kharaelakh ore-rich intrusions have been found to diverge. The intrusions’ isotope characteristics form regression lines with the Kharaelakh intrusion having the highest atmospheric contribution of Ar and the Norilsk-1—the...

Chapter 8Isotope Chronology of Geological Processes

Petrov, O.; Sergeev, S.; Krymsky, R.; Presnyakov, S.; Rodionov, N.; Larionov, A.; Lepekhina, E.; Sergeev, D.

Pages: 215 –302

[The chapter presents new geochronologic results of various isotope techniques (U–Pb SIMS and Re–Os TIMS) along with their comparison with already published data. The main intrusions of the Norilsk district are demonstrated to be emplaced almost simultaneously with two possible magma intrusion...
