在金屬矿床的地質勘探中,为正确了解矿床中有用金屬或伴生有益組份及有害元素的含量,从而圈定工业矿体,計算儲量,必須借助于系統地化学取样及化学分析。因此正确地选擇化学取样方法,保証所采取的样品具有足够的代表性,不仅直接影响到化学分析的作用和效果;同时在经济上,时间上也具有十分重要的意义。为此,茲根据笔者在有关金属矿区进行取样試驗的结果,并参照几年来在勘探內生热液矿床化学取样工作所积累的资料,做一初步探討。
In the geological prospecting of metal deposits, in order to correctly understand the content of useful metals or associated beneficial components and harmful elements in the deposit, it is necessary to delineate industrial orebodies and calculate reserves by means of systematic chemical sampling and chemical analysis. Therefore, the correct choice of chemical sampling methods to ensure that the samples taken are adequately represented, not only directly affect the role and effectiveness of chemical analysis; the same time, economically, time is also of great significance. For this reason, based on the author’s results of sampling experiments conducted in the relevant metal mines and based on the data accumulated in the chemical sampling of exploration endogenic hydrothermal deposits over the past few years, a preliminary study was conducted.
