Abstract
A geological age measurement apparatus by the color measurement of zirconium comprises an arithmetic recording computer including a recording medium input/output unit medium connected to both a measured result storage medium and a control storage medium including a calibration curve preparation program showing the relation between the color of zirconium and its geological age, an age arithmetic program for calculating the geological age from the color and a basic program. The apparatus allows the evaluation of geological age by color measurement easily, promptly and inexpensively without using any large expensive instruments. The evaluation of geothermal heat storage layers and heat source is done almost spontaneously while geothermal walls are being bored for their tests.
