Develop the field of geological data services, geological exploration data

The comprehensive collection of mineral exploration data in the application area is the most important basic work for the study of metallogenic geological conditions, ore-controlling factors and metallogenic laws, and is also the main geological basis for the study of typical ore deposit characteristics, the reasonable division of metallogenic series (systems) and mineralization types, and the scientific evaluation. Whether the basic data related to mineral exploration and geological research can be comprehensively collected and applied will directly affect the reliability of the results of regional mineral evaluation.

This time, more than 120 exploration data of ore deposits, ore points and mineralization points in the whole region were collected and applied. In accordance with the technical requirements of ore deposit evaluation and mineral land database construction, collect and fill in mineral geological cards one by one. The content is mainly metallogenic geological environment, geological characteristics of ore deposits, exploration and research degree, main prospecting signs and existing problems.

For example, the geology of ore deposits includes ore-bearing strata, magmatic rocks, ore control (capacity) structures, ore body characteristics (morphology, occurrence, grade, etc.), surrounding rock alteration characteristics, ore mineral composition, ore structure and structure, metallogenic age, etc. The data collection card of the typical mineral area should also be attached to the geological sketch map and typical section map of the mining area.

It should be pointed out that some mineral fields in the area have undergone many exploration works, and the latest exploration results should be fully utilized. For some survey materials that have been completed for a long time, they should be identified one by one and the inappropriate points should be corrected. For example, with the improvement of the degree of geological research and the progress of science and technology, the stratigraphic division and age attribution, the formation age of magmatic rocks, the reasonable division of ore deposit types, the distribution of fault structures and their properties, etc., should also be revised and supplemented accordingly and given new contents.

In short, it is necessary to unify all basic information in the region to the same new level of understanding, so as to make the evaluation work more solid and reliable.

With the continuous development of social economy, resource and environmental problems are becoming more and more serious, so the dependence and demand for geological work are getting higher and higher. At the same time, with the deepening of geological work, the difficulty of mineral resources and geological environment exploration and evaluation is increasing, and the investment risk of the geological market is also increasing

1) Management decision-making: through the statistical analysis and compilation of physical geological data, for the geological and mineral resources or land and resources management departments at all levels to formulate relevant guidelines, policies, regulations, planning, standards and provide information support and reference for the organization and management of geological work.

2) Geological exploration, geological research, mineral development: to provide a direct basis for the deployment and implementation of geological exploration, geological research, and mineral development, so as to avoid duplication of work, reduce investment risks, improve work efficiency and work level, and promote the development of geological market and geological work.

3) Professional education and science popularization: The physical geological data museum has a large number of various types of physical objects and related materials from home and abroad, not only many ornamental rare treasures, but also representative physical geological data that reflect the regional geological conditions and major geological work results, so it has a strong data and archival nature.

Based on these characteristics, physical geological data is an important teaching resource, physical geological data is a good off-campus classroom and practice base for geological colleges, where auxiliary teaching and practical education can be carried out, not only can receive good results, but also can save input, so as to achieve twice the result with half the effort.

In addition, with the help of physical geological data and physical geological data museum, we can publicize and popularize earth science knowledge to young people and the public, display the major achievements and latest progress of China's geological and mineral conditions and geological engineering closed manuscripts, stimulate young people's interest in earth science, improve social awareness of resources and environment, and create a broad social foundation for human beings to understand the earth, rationally use and protect the earth.

The electronic reading system was officially launched. The dust attack has realized the integration of geological data inquiry, borrowing, processing, user information management, service volume statistics and other functions, and significantly improved the informatization level of geological data services. Before the Ming Dynasty, there were 10,000 digitized geological data and 1:

200,000 digital geological maps are provided in the electronic reading system, and the amount of online data has reached 9TB.

The utilization rate of materials in the collection has increased steadily. The National Geological Archives received 1.17 million borrowers throughout the year, providing 37,325 copies and 158283 10,000 pieces of materials. Geological data collection institutions at the ministerial and provincial levels have provided borrowing services for 40,000 people.

Emergency services and double insurance services won honors. In the face of severe drought in North China, the Jianghuai River Basin, and the middle and lower reaches of the Yangtze River, the National Geological Archives launched drought emergency services in a timely manner and established a green channel for drought relief emergency services. In view of the urgent demand for geological data in the construction of key projects such as railways, electric power, and highways, we actively carried out the service of "ensuring development and red line", and won the honorary title of "pioneering model and service model".

The National Geological Archives received 10,000 visitors through various service methods, processed and copied 10,000 geological maps (calculated according to the equivalent of 200,000 standard maps), and the data volume reached 495GB.

The national medium-scale regional geological survey and related results public data products have been formed. Completed the development of 1.2 million geological maps and their survey reports, 1.2 million hydrogeological maps and their investigation reports, 1:250,000 geological maps and their investigation reports, 1.25 million construction and structural maps and 1.5 million geological maps covering the whole country.

The construction of the global mineral resources information system has been further improved. The global mineral resources information covers 117 countries, processes and copies 335 overseas geological maps, provides services for 107 units, and provides data services of 172GB.
