We considered fitting the lineaments to the set of the points extracted from the picturewhich expressed the geographical structures. In the case when a coefficient of linear equation which expresses the lineament is calculated by the method of least square for distance between thepoints and a straight line, the fittings among the linear equations of each sets of points can becompared by the averages of the residual sum of squares.
In this paper, all points are expressed on a plane coordinates and objective variable y is expressed by the function f (x) .When the coefficient of f (x) to minimize the residual sum of squares between measured value yi and f (xi) is calculated, accuracy of the function can be expressed by the correlation coefficient.
Therefore, we moved the origin of coordinates to the center of set of points and rotated the coordinates at the point to calculate the maximum correlation coefficient. Moreover, it was proved that the linear equation with the maximum correlation coefficient was equivalent to the straight line derived by the method of least square for distance between the points and a straight line.
We showed the comparison results of the accuracy of the fitting lineament on the region where gold deposit exists as an example of application of this method.

In the present paper we discuss a method for estimation of contamination of detritus grains in fission track measurement and present a statistical treatment for overcoming these contaminant affects. Fission Track data were obtained from the two zircon sample from different horizons in an acidic tuff outcrop belonging to the Hanazono Formation (HZ0) in southwest Japan. The x²-test of fission track data suggest that non-Poisson's distribution exist in the sample (HZ0-1) from the lower most HZ0.This result indicate that HZ0-1 contains detritus grains in the data set. Result from another sample (HZ0-2) which is 1.7m above the HZ0-1 does not indicate the existence of a non-Poisson's distribution. In further analysis the raw fission track data set of HZ0-1 was divided into two groups based on the zircon morphology. Next, the x² test to the each separated sample were carried out. it is observed that one set of samples show non-Poisson's distribution whereas the other set does not. This result indicates that the detritus zircon show characteristic crystal form and can be identified and separated based on their mor-phology. It was also showed that the population of HZ0-1 sample showing Poisson's distribution is almost the same population of the zircon crystals derived from the sample HZ0-2. Based on above result, the utility of zircon crystal morphology and the use of statistical techniques for minimizing contaminant affects are highlighted.
