Foreword
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents".
Drafting.
This document supersedes GB/T 17366-1998 "Preparation Methods of Samples for Electron Probe Analysis of Minerals and Rocks", and is consistent with GB/T 17366-
Compared to.1998, aside from structural adjustments and editorial changes, the main technical changes are as follows.
a) The "Method Summary" (see Chapter 3 of the.1998 edition) has been removed;
b) Added terms and definitions (see Chapter 3);
c) The requirements for instruments, equipment, and materials have been changed (see Chapter 4, Chapter 4 of the.1998 edition);
d) The labeling for the preparation and analysis locations of block samples, particulate samples, and fine powder samples has been changed (see 6.2–6.5,.1998 edition).
(6.1~6.4 and Chapter 7);
e) The coating on the sample was changed (see Chapter 7, Chapter 8 in the.1998 edition).

Microbeam analysis electron probe microscopy
Methods for preparing mineral and rock samples
1.Scope
This document describes a general method for preparing samples for electron probe microanalysis of various minerals, rocks, and other geological samples.
This document applies to the preparation of samples for electron probe microanalysis of minerals and rocks.
2 Normative references
The contents of the following documents, through normative references within the text, constitute essential provisions of this document. Dated citations are not included.
For references to documents, only the version corresponding to that date applies to this document; for undated references, the latest version (including all amendments) applies.
This document.
GB/T 41074 Powder sample preparation method for microbeam analysis for wave spectroscopy and energy spectroscopy
3.Terms and Definitions
The following terms and definitions apply to this document.
3.1
polished section
The blocky rock or ore sample is cut and ground into a sample of a certain size, polished on one side, and can be observed under a microscope under reflected light.
Note. Light slides are generally suitable for samples containing a large amount of opaque metallic minerals.
3.2
thin section
The blocky rock or ore sample is cut and ground into a sample of a certain size, polished on both sides, and can be observed under a microscope under transmitted and reflected light.
Note. Thin sections are generally suitable for rock samples that are mainly composed of transparent minerals. The grinding thickness is generally 30μm~100μm depending on the needs of microscopic observation.
3.3
sandpolished section; sandpolished mount
The sample is prepared by embedding the particulate sample and then grinding and polishing it.
Note. Sanding sheets are generally used for particle samples of millimeter size and below. Sometimes, irregular block samples of centimeter size are also embedded to make regular sanding sheets.
4.Instruments, equipment and materials

4.1.1 Vacuum coating machine.
4.1.2 Ultrasonic cleaning device.
4.1.3 Optical microscope.
4.1.4 Slicer (cutting machine).
