Preliminary exploration into the revision of the Technical Symbols for Geochemical Exploration
-
摘要: 《地球化学勘查技术符号》(GB/T 14839—1993)是20世纪90年代初制定的国家标准,共收录符号101个。2019年开始对其开展修订工作,确定的修订原则如下:①继承原有符号原则——尽量保持原标准内容的稳定性和延续性;②新增符号选择应符合专业习惯原则——尽可能选择目前地球化学勘查中已经广泛使用、获得大部分同行认可的符号;③与地球化学勘查技术专业领域发展相匹配原则——修订后的“地球化学勘查符号”应全面覆盖当前地球化学勘查的所有领域;④以常用地球化学符号为主原则——以常用地球化学符号为收录范围。根据以上原则,新增了生态地球化学调查评价类专用技术符号,扩充了地球化学勘查通用技术符号和矿产地球化学勘查亚类、地球化学样品测试亚类等专用技术符号。修订后的《地球化学勘查技术符号》增至173个,按照使用广度划分为通用和专用地球化学符号两大类,其中专用地球化学符号依据应用领域进一步细分为矿产勘查、生态环境调查评价和样品测试地球化学技术符号3个亚类,涵盖范围与当前地球化学勘查技术应用领域相匹配。Abstract: 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.
