Introduction

Carbonate minerals are widely distributed in various geological bodies, and accurate quantitative analysis of their elemental composition is very important in earth science. Probe analysis is the main method for quantitative analysis of the micro-area composition of carbonate minerals. Under beam bombardment, element evaporation occurs, causing the counting intensity to change over time. In addition, carbon in carbonate minerals is generally not directly used for Therefore, it is necessary to develop a carbonate mineral quantitative analysis method. Standard for quantitative electron probe analysis of mineral components, working conditions, analysis process and reference materials in electron probe analysis of carbonate minerals Carbonate minerals can be divided into anhydrous carbonates and hydrous carbonates. The quantitative analysis of the composition of hydrous carbonates is more influencing. This document is mainly aimed at the quantitative analysis of anhydrous carbonate minerals by electron microprobe. Microbeam analysis Electron probe microscopy Quantitative Analysis Methods for Anhydrous Carbonate Minerals
