Research Abstract

(1) The measurement of the 3-D track-geometry has the potential of providing evaluations of dating procedures and to aid in understanding the thermal history of geological samples.
(2) The determination of the 3-D track-geometry in a mineral is made from a set of fission track data that consists of the location of etch-pits, azimuth angles to the C-axis, dip angles to a surface and actual semi-track lengths. It is quite impossible to measure the 3-D track-geometry from a single picture of tracks, so it is necessary to take a series of pictures at stepped focussing points and compose and display them on an R.G.B. monitor as a colored picture. A system operator interactively checks the qualifications necessary for measurable track-images within the colored picture, and the operator is expected to have sufficient knowledge of the relationship between the characteristics of the colored images and the stereographic views of the 3-D track-geometry.
(3) Since 1988, we are accumulating these knowledges in the form of subroutine program modules and the conditional equations to the operations.
(4) We got the full system for the fission-track dating with Grant-in-aid ( microscopes, a workstation, and basic softwares with an expart software ). We have developed many application programs on that system, which has an ability of automated fission-track dating with artificial intelligence. This is very powerful for fission-track dating using for not only minerals but also natural glass.
