The Technical Symbols for Geochemical Exploration (GB/T 14839-93) is a national standard formulated in the early 1990s, including 101 symbols. The revision of this standard began in 2019 according to the following principles: (a) Inheriting the original symbols. The stability and continuity of the original standard content should be maintained as far as possible; (b) Selecting new symbols in line with professional habits. It is necessary to select symbols that are widely used in geochemical exploration and are recognized by most peers as far as possible; (c) Matching the development of geochemical exploration technologies. The revised technical symbols for geochemical exploration should cover all fields involved in the current geochemical explorations; (d) Focusing on the commonly used geochemical symbols. The commonly used geochemical symbols should be included. According to the above principles, special technical symbols for ecological geochemical surveys and evaluation were newly added, and the expanded symbols include general technical symbols for geochemical exploration and special technical symbols for mineral geochemical exploration and geochemical sample testing. A total of 173 symbols were included in the revised standard. The revised technical symbols for geochemical exploration can be divided into a general type and a special type according to their application scopes. The special geochemical symbols can be categorized into three subtypes according to their application fields, namely mineral exploration, ecological environment investigation and evaluation, and geochemical sample testing. The fields covered by the revised standard are consistent with the current application fields of geochemical exploration technologies.
