Fission track dating of obsidians

Nuclear Tracks, 1981
Abstract Fission-track dating is applied to 16 obsidian artifacts from an archaeological excavation at Cayonu Tepesi in southeastern Anatolia. Since obsidian samples are rich in bubbles and inclusions, only the six most compact samples were found to be usable for fission-track measurements.

Neutrons for fission-track dating and fission tracks for neutron spectrum monitoring

Acta Physica Hungarica, 1994
An account is given of our experiences in the absolute calibration of Fission Track dating, based on coirradiation with the sample either of metal monitors or of uranium-doped glass monitors. Secondly, the (Corning) CN3 and CN5 glasses, with a largely different Th/U ratio, were used to characterize the neutron spectrum in channel 4 of reactor Thetis ...

Particle Tracks and Fission Tracks

1992
A fast charged particle, when passing through an insulating solid, creates a narrow trail of damage along its trajectory. This damage trail persists in the solid after the particle has come to rest and is called a charged particle track or nuclear track. The solid in which the tracks are registered is commonly called the detector.

Fission Track Annealing and Fission Track Age-Temperature Relationship in Sphene

Nuclear Technology, 1981
Annealing characteristics of spontaneous (fossil) and induced (recent) fission tracks in sphene were measured in a temperature range of 873 to 768 K.

Etching Fission Tracks in Zircons

Science, 1969
A new technique has been developed whereby fission tracks can be etched in zircon with a solution of sodium hydroxide at 220°C. Etching time varied between 15 minutes and 5 hours. Colored zircon required less etching time than the colorless varieties.

Fission-Track Dating and Geologic Annealing of Fission Tracks

1979
Fission-track dating is one of the newest methods that geologists have to help them determine the ages of minerals and natural glasses. Fission tracks are stable over different temperature intervals in different minerals and glasses,and by dating several different minerals present in a rock it is possible to obtain a better understanding of its thermal
