CB/T 9649.25—1998
Informatization in the field of geology and mineral resources has been rising in countries around the world. my country needs to catch up with the world's advanced level, introduce modern information technology, develop my country's information resources, and build various geological and mineral information systems. In 1984, the Ministry of Geology and Mineral Resources proposed to formulate the basic technical standard of information classification code for the construction of geological and mineral information system to ensure the information sharing between various information systems to be built. In 1985, the project was approved by the national standardization department to formulate GB/T9649-88 series of "National Standards for Classification Codes of Geological and Mineral Terms", which consists of 35 parts: cosmic geology, geophysics, volcanic geology, geogeology, exodynamic geology, geomorphology, tectonic geography, structural geology, structure and mineralogy, petrology, geochemistry, rock and mineral identification, chemical analysis, geohistory and stratigraphy, paleogeography, ore deposits, coal geology, petroleum and natural gas geology, ocean geology, hydrogeology, geothermal geology, environmental geology, geoeconomics, remote sensing geology, scientific geology, regional geological survey, geophysical exploration, geochemical exploration, mining geology and mining, ore dressing and metallurgy, solid mineral survey and exploration, prospecting engineering, geophysics, and surveying and mapping. GB/T9649-88 National Standard for Classification Code of Geological and Mineral Terms mainly integrates various geological phenomena in geological and mineral production and scientific research, collects various related information and uses the text values ​​to describe the attribute characteristics. In order to facilitate application and division of labor in compilation, and avoid duplication and omission of content, subject classification is adopted for compilation. After consultation, appropriate division of labor is made for the overlapping parts between subjects to ensure the overall systematicity, integrity and uniqueness. Character codes are given to terms used as data items (exhaustiveness), and a coding scheme combining surface classification and line classification is adopted, which can maintain uniqueness and have sufficient room for expansion. There will be no duplicate codes when supplementing with the needs of application. Terms used as text values ​​are generally coded with numbers, which is conducive to storage, retrieval, space saving and improved processing speed.
GB/T9649-88 National Standard took two years to develop. After the joint efforts of more than 100 experts from 20 teaching, scientific research and production units with their own expertise, it was revised four times and the fifth draft was finalized. Under the auspices of the China Institute of Standardization and Information Classification and Coding, the national standardization unit, the standard coordination and review team, which was attended by experts from relevant departments such as quality, metallurgy, nonferrous metals, chemicals, coal, petroleum, ocean, nuclear industry, building materials, and railways, completed the draft for approval after three rounds of coordination and review. In order to maintain the stability and unity of the GB/T9649-B8 national standard during its implementation, the national standard authority entrusted the National Geological Data Bureau (now merged into the China Institute of Geological and Mineral Resources Information) to be responsible for maintenance and service. Users have no right to modify it at will during use. When there are requirements for additions and modifications, they must contact the maintenance unit and obtain approval from the maintenance unit before they can be included in the standard content for use. They will be formally included in this standard when this standard is revised.
After five years of application, the GB/T9649-88 national standard was revised in 1993 according to user requirements. Due to actual needs, only some disciplines were revised this time, and a series of standards were adopted to facilitate user use and future revisions. The principle of revision is to make appropriate additions and modifications while keeping the overall structure unchanged. iB/T9649-88 Classification Code for Geological and Mineral Terminology "Geophysical Exploration" is compiled by Changchun Institute of Geology, and the main drafters are: Sun Yunsheng, Li Qingxuan, Shi Baolin, Chen Jihong, Wang Xingtai, Xu Shengyan. This standard is a revision of the national standard GB/T9649B88 Classification Code for Geological and Mineral Terminology "Geophysical Exploration" part, and the standard code is GB/T9619.28. There are two main revisions to this standard. One is that it adopts the term "correction" in the national standard "Geophysical Exploration Terminology". All the terms containing "correction" in the content of GiB/T9649-88 national standard "Geophysical Exploration" are changed to "correction"; for "electrical prospecting methods" and so on Geophysical prospecting methods are coded in three digits to facilitate the use of users. Secondly, the terms such as "abnormal type", "abnormal inspection" and other abnormal parameters are added, and the gravity measurement method and geophysical exploration method are added. The new content represents the development direction of the discipline: This standard is proposed by the Ministry of Geology and Mineral Resources. This standard is under the jurisdiction of the China Institute of Standardization and Information Classification and Coding. This standard is also organized and drafted by the China Institute of Geology and Mineral Resources Information. The main authors of this standard are: Fan Zhankui, Yue Jingman, Ma Deyao, Gong Yikai, and Li Qingxuan. 1.7

Partially replaced by GB/T 9645BB
The standard specifies the content of "geophysical exploration\discipline, including gravity, magnetic, electrical, seismic, logging, radioactive and various physical operations for land, air and sea, data collection, various physical parameters, methods and means, instruments and equipment, data interpretation and results maps, etc. This standard is applicable to the construction of various geological and mineral information systems. If there is information exchange to achieve information sharing, this standard should be used. 2 Definitions
This standard adopts the following definitions.
2.1 Data item: refers to the terminology that reflects the basic nature of various geological entities and their working layer concepts. 2.2 Textual terms: refers to the terminology used to make a specific qualitative description of the basic attributes of geological entities. 3 Classification principles
3.1 This standard adopts the surface classification method to divide geological science into 35 major disciplines in accordance with the principles of easy compilation and use, minimizing code redundancy while leaving room for expansion, and strictly divides the boundaries to maintain the overall systematicity and integrity and avoid duplication and overlap of content. 3.2 Under the major categories, a three-level tree classification is adopted, from middle category, small category to basic data item name. The content levels of each discipline are different, and the lower level can be reduced. Under the condition that the coding capacity allows, it can also be divided into four levels: 3.3 Classification at all levels is scientific, systematic and universal. 4 Principles of word selection
4.1 Objects of word selection: terms that may be used as data items of various geological and mineral databases (including the upper level of data items selected from the classification sense), as well as terms used to describe the literary value of data items qualitatively. The selected terms are consistent with the current relevant national standards, and various current geological work specifications are referred to as much as possible.
4.2 The terms used for data items in this standard are not unique. Any synonyms are marked in the remarks column for reference, but shall not be used when building the database.
4.3 The selected terms are simple, clear and unambiguous. Fully consider the needs of establishing a database. 4.4 In order to ensure the integrity and systematicness of the "Geological and Mineral Terminology Classification Code" and avoid duplication, the content already included in the basic disciplines will no longer be selected in the applied disciplines, and only the unique content of emerging disciplines and marginal disciplines will be selected. For instructions on the attribution of the scope of classification selection, see Appendix A. 4.5 Appropriately select some terms that reflect the new direction and new level of discipline development. 4.6 For the convenience of use, individual data items with high frequency of use can be repeated in different disciplines, but they must be uniformly coded to ensure the uniqueness of the code. The text values ​​under different data items can be repeated in small amounts. 5 Coding method 5.1 Data items are coded with no more than six Latin letters (written by humans): - generally divided into four levels. The structure is as follows: x
Middle category Small category data item
The major categories take the modified phonetic initials of two Chinese characters that can reflect the meaning of the category as the code, which has a certain readability. For example, "Structural Geology\\GZ\ is the code. The following is a tree-like nested format. The middle and small categories are arranged in alphabetical order from A to 2..., and the last two digits are basic data items. There are many of them, so they are arranged in the order of AA-ZZ. If there is a need for classification and there is enough room for expansion, the last two digits can also be divided into two levels. 5.2. The length of the text value is generally determined by the classification needs, the number of text values ​​and the expansion margin left. It is shortened as much as possible and the excess is kept to a minimum. The text values ​​are classified into different levels and the numbers are used in a serial manner. The text values ​​under the same data item are of equal length. Some text values ​​(such as chemical element levels, etc.) continue to use the original international or domestic common character codes. 6. Use and management
6.1 Usage
This standard is provided in two forms: written and magnetic. Users can select the required terms and their codes from various disciplines according to their own database construction purposes as the data dictionary of their own systems. 6.2 If the content of this standard cannot meet a certain need, you can propose the content to be supplemented and report it to the standard management unit for supplementation in the corresponding discipline, and give a code for use. It is not allowed to add words or codes on your own. In this way, you can meet the needs and maintain the stability of the standard. New content will be added when the standard is revised. 7 Code content setting
To meet the requirements of different types and forms, the classification and code table has four columns: code, Chinese name, English translation (Latin name for paleontology) and remarks.
