Recently, through geological surveys and researches, China has established a number of innovative new geotechnical experimental testing technologies and methods that have been developed simultaneously with the international community.
In terms of inorganic testing and analysis technology, we have established large-scale modern analytical instruments such as X-ray fluorescence spectrometry, plasma atomic emission spectrometry, and plasma mass spectrometry for the needs of China's geological survey, supplemented by other classical analytical techniques. Elemental analysis system scheme. Focused on solving the problem of fast quantitative analysis of some of the 76 elements that are required for geochemical analysis. Some of these methods have filled gaps in the domestic standard and greatly improved the overall analytical skills.
In the area of ​​organic testing and analysis technologies, technical methods for major organic matters in the multi-target geological survey, important organic pollutants in groundwater, and energy organic geochemistry experimental tests were developed, resulting in a relatively rapid and economical organic pollution in geological samples. Analytical methods. A total of 37 priority control organic pollutants of 25 volatile halogenated hydrocarbons, benzene series, 11 organochlorine pesticides, and 1 polycyclic aromatic hydrocarbon were analyzed. Based on this, a test method for 37 organic components that must be measured in the groundwater pollution investigation in the country has been established and applied in the industry.
In terms of isotope analysis testing technology, China introduced the first high-sensitivity and high-resolution ion probe mass spectrometer in China and developed corresponding testing technologies. It has obtained many world-class research results in the Precambrian geological research. The first silicon isotope analysis laboratory in China was established, and both technology research and application research are in a leading position internationally. The first La-Ce statutory laboratory in China, the apatite (U-Th)/He isotope dating laboratory, and the first domestic Mg isotope measurement laboratory were established. For the first time domestically established non-mass effect analysis methods for nitrogen and oxygen isotopes and oxygen isotopes of nitrates, in-situ boron isotope analysis methods for microdomains, and copper-zinc isotope analysis methods are provided for the direct use of isotopic tracer ore-forming material sources for ore-forming elements. Strong support. He took the lead in domestic research on laser argon-argon dating technology, and brought China's argon-argon isotope chronology into micro-domains.
In terms of on-site analysis of new technologies and new methods, through the development of the Continental Scientific Drilling Project, the development of on-site analysis technologies has been strongly promoted, and in particular, scientific drilling fluid analysis techniques have reached international standards. “Multi-functional on-board field experiment analysis equipment†is oriented to mineral exploration in remote covered areas in the west, integrating shallow drilling sampling, sample preparation, and on-site analysis, and has achieved good application results.
In terms of the development of geological analysis instruments, portable X-ray fluorescence spectrometers and portable near-infrared mineral analyzers have been successfully developed, and X-ray fluorescence spectrometers have been ranked first in the world for field analysis on oceanographic research ships. Other instruments that have been successfully developed include portable light guide colorimeters, ultraviolet/visible spectrophotometers and more than a dozen instruments. Among them, some have been mass produced and serialized.
For the development of reference materials, more than 160 kinds of national standard materials such as carbonate rock composition analysis reference materials and series of metal ore component analysis reference materials have been developed. At present, we are still working on the development of many standard materials such as polymetallic ores, quartzite chemical compositions, sillimanite, and Antarctic marine sediments.
In laboratory quality monitoring and management, the laboratory information management system (LIMS) and experimental test quality control methods were developed and began to be promoted in the national geological laboratory.
