WebAutoscan Systems Pty. Ltd. is an Australian scientific instrument manufacturing company which first manufactured equipment for the geological technique of fission track dating in 1979, and which was incorporated under the current name in 1984. Since that time, we have become the world's leading manufacturer and supplier of automated microscope ... WebAbstract. A new method for automatic counting of etched fission tracks in minerals is described and presented in this article. Artificial intelligence techniques such as deep neural networks and computer vision were trained to detect fission surface semi-tracks on images. The deep neural networks can be used in an open-source computer program for semi …

Web2 days ago · Statistics for Fission Track Analysis explores the line segment model and its consequences for the analysis and interpretation of data. The author derives the equations for fission track data and the theoretical probability distributions for the number, orientation, and length measurements of the tracks. Fission track dating is a radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium-bearing minerals and glasses. Fission-track dating is a relatively simple method of radiometric dating that has made a significant impact on understanding the thermal history of continental crust, the timing of volcanic events, and the sourc…

WebFission track dating is based on the number of 238 U spontaneous fission tracks accumulated in a mineral from the formation of the mineral. If the temperature of the geological body containing the mineral was too high to retain fission tracks, the tracks formed in this period would be completely lost.
