用放射方法測定岩石矿物的絕对年龄是地球化学領域中一个新方向。虽然这門学科差不多已有半个世紀的历史,但是此項研究在我国还刚开始。目前一些研究单位正在积极筹建絕对年龄測定实驗室。截至目前为止,关于测定样品的采集和加工工作,有的地貭工作者还不能十分确定。为了使样品能适合于絕对年龄測定的要求有必要对样品的采集加工和有关的注意事項进行詳細的說明。首先采样时必須附有采样单和較詳細的說明书,包括样品編号、采集的地点——省、市(县)、村。在地貭情况的叙述部分应附簡要的地貭图或剖面图(在图上标明采样位 Determining the absolute age of rock minerals by radiation is a new direction in the field of geochemistry. Although this discipline is almost half a century old, this research has just begun in our country. At present, some research institutes are actively planning to build an absolute age determination laboratory. Up to now, some workers have not been able to determine the sample collection and processing work. In order to make the sample suitable for the determination of absolute age, it is necessary to explain the sample collection and processing and related precautions in detail. The first sampling must be accompanied by a sampling list and a more detailed instructions, including the sample number, the collection location - province, city (county), village. The description of the situation in the territory should be accompanied by a brief map or section of the map (indicating the location of the sample
