In this paper, we consider the application of the U-Th-He method of isotope geochronology for native gold dating. It was shown that inclusions of uranium- and thorium-bearing minerals, including rare earth element phosphates, are one of the main form

The Xes-Xen dating of zircons from rocks of the Rayner Complex of the Enderby Land at the Molodezhnaya Station area (coast of the Alasheyev Bight) yielded age estimates of 550 ± 50 and 1040 ± 30 Ma. The metamorphic rocks of the Rayner Complex recor

A new method of isotope geochronology was proposed for dating native platinum minerals on the basis of the α-decay of the natural isotope 190Pt. The analysis of the thermal desorption of helium in the crystal lattice of native metals, including plat

It was shown that the behavior of 4He in native and technical metals is very similar owing to the symmetric and stable electron shells of its atoms, which cannot gain electrons from other atoms or donate their own electrons to metal atoms in a crysta

A new method of determining the age of native platinum based on alpha-radioactivity of one of its natural isotopes 190Pt is proposed. Due to a special form of occurrence of radiogenic helium in the crystal lattice of native metals as a helium cluster

The kinetics of He migration from zircon of variable degree of metamictization was investigated. The migration parameters of He were experimentally determined, the influence of radiation damage and the degree of metamictization on the stability of th

For investigation of helium in native gold, a new measuring complex was created and used: the high sensitivity mass spectrometer MSU-G (ZAO SKB “SPECTRON”). The sensitivity of measuring 4He was 5.3 × 10−13 cm3/g per impulse. Experiments in ste

Fines, microbreccias and agglutinates from the Luna 16 mature regolith 1635 and fines from the immature/submature Luna-24 regolith have been analysed for N and argon isotopes in order to understand the origin of isotopically distinct N released at di

The isotopic composition of the noble gases of the new Martian meteorite, the Dhofar 019 shergottite, found in the desert in the territory of the Sultanate of Oman on January 24, 2001, was investigated. Stepwise thermal annealing with isotopic analys

Noble gas studies of fine-grained silicate material of the Efremovka carbonaceous chondrite revealed the presence of excess 36Ar over and above the level expected due to contributions from the trapped and cosmic-ray-produced, both spallogenic and sec
