On epidote fission track dating

Radiation Measurements, 2005
Abstract The use of epidote in fission track dating was abandoned since the beginning of the 1980s due to difficulties like absence of a standard etching procedure, obtainment of different closure temperatures and the percentage of the datable samples.

Fission track dating of quartz

Nuclear Tracks and Radiation Measurements (1993), 1993
Abstract Fission track dating of quartz vein containing gold has been carried out by using artificial heavy quartz grains and the chemical etching technique of quartz has been improved with in 65% NaOH. Fission track ages of five quartz samples are from 100 Ma to 200 Ma.

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.

Fission track dating of zeolites

Nature, 1981
The fission track method has become acceptable in geochronology, not only in straightforward dating of igneous and metamorphic events but also in stratigraphic studies by the dating of ash layers1,2, the elucidation of crustal uplift history3–7, and in archaeology8.

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 ...

Fission track dating applied to the plio-pleistocene

Nuclear Tracks, 1981
ABSTRACT Mammal deposits of the plio-pleistocene French Massif Central have been dated by the fission track method using sphene, apatite and zircon minerals. The results confirm a greater volcanic activity registered during the pliocene period. The Massif Central volcanic history is investigated.

A study on standardization of fission track dating

Nuclear Tracks and Radiation Measurements, 1993
Abstract Two methods were used to improve procedures of fission track dating: (1) to measure absolute neutron fluence using SRM 962 uranium dosimeter glass calibrated against Co activation foils; (2) to determine zeta calibration constant. The calibration factor B was measured from 12 irradiations to be (5.79 ± 0.29) × 10 9 neutron/track.
