不同的勘探阶段,有它不同的地質目的,因而,包括化学分析在內的所有措施亦应有所不同。我仅就鉄矿石普通分析項目分期确定問題,略談一点不成熱的意見。一、找矿阶段在初步找矿阶段,为了达到对矿产的一般了解,必須做些观測工作,从而說明該区的矿产价值。在这个阶段,对于矿石的質量的优劣,要采取快速的分析方法。因此,我認为,要选擇几块代表性的标本(根据矿体規模,矿化均勻性質等因素),进行主要組份TFe的分析,并同时利用这几块标本作光譜分析与显微鏡观察工作。做光譜分析和显微鏡观察,可有下列一些效果: Different exploration stages have their different geological objectives and therefore all measures, including chemical analysis, should also be different. I only 鉄 鉄 ore general analysis project to determine the issue of staging, a little hot opinion. First, the prospecting stage In the preliminary prospecting stage, in order to achieve a general understanding of minerals, we must do some observations to illustrate the area’s mineral value. At this stage, for the pros and cons of ore quality, to take a rapid analysis. Therefore, in my opinion, we should select a few representative specimens (according to the size of ore body, the nature of mineralization and other factors), the analysis of the main component of TFe, and at the same time the use of these specimens for spectral analysis and microscopy Mirror observation work. Do spectral analysis and microscopic observation, can have some of the following effects:
