Abstract

The effect of laser radiation on the surface and volume of natural quartz of the Bural-Sardyk deposit (East Sayan, Buryatia) is studied. The influence of the main parameters of laser radiation with a wavelength of 213 nm (prefix NWR-213) and the properties of the sample on the results of elemental mass spectrometric analysis with inductively coupled plasma are established. The features of laser ablation of various microinclusions in quartz are considered. The main problems arising from the laser evaporation of fluid inclusions in quartzites for the quantitative determination of their chemical composition are indicated.

摘要

研究了激光辐射对Bural-Sardyk矿床（East Sayan，Buryatia）天然石英表面和体积的影响。建立了波长为213 nm的激光辐射的主要参数（前缀NWR-213）的影响以及样品的性质对电感耦合等离子体元素质谱分析结果的影响。考虑了石英中各种微夹杂物的激光烧蚀特征。指出了由激光蒸发石英岩中的流体包裹体以定量确定其化学成分所引起的主要问题。
