| Research Abstract |
We tackled the construction of the technique which makes an age decision of production remains using the carbon contained in the phytolith of Gramineae stably detected from soils. As a result, we succeeded in the setting of the best condition and technical development about the four processes (plant opal extraction from soil, contaminated carbon removal, carbon extraction from plant opal,age determination) that constitute this technique. Although there is room for considerations about the accuracy of age determination, we have constructed a series of techniques of measuring the age of production remains.
