氟通常在岩浆结晶作用晚期浓集于残余的流体和蒸气中,所以它富集在花岗岩和碱性岩里。这种浓集和由此造成的富集乃是氟始终以痕量或少量及大量存留于几乎所有类型矿床中的主要原因。因此,许多矿床都有正的原生氟晕。在最近几年里对氟的迁移,对用氟值作为氟矿床和氟在其中是伴生元素的矿床的指示剂等一直在进行大量的工作。本报告提出了一种改进的离子选择电极法分析岩石和土壤样品中的氟,以助于矿床的勘探。 Fluorine usually concentrates in residual fluids and vapors in the late stage of the magma crystallization, so it is enriched in granites and alkaline rocks. This concentration and the resulting enrichment are the main reasons why fluorine remains in almost all types of deposits, always in trace or small amounts, and in large quantities. As a result, many deposits have positive primary haloes. Much work has been done on the migration of fluorine in recent years, on the use of fluorine as an indicator of fluorine deposits and fluorine deposits in which they are associated elements. This report presents an improved ion-selective electrode method for the analysis of fluorine in rock and soil samples to aid exploration of the deposit.
