A new mineral in nature, called empty tetrahedrite, was discovered in Henan Province. Kongtie tetrahedrite was discovered in Yindongpo Gold Mine, Tongbai County, Nanyang City, Henan Province, and it is the ninth member of the international new mineral family belonging to "Henan nationality". A new mineral named dawsonite has been discovered in Henan Province.
A new mineral in nature was discovered in Henan province, named empty tetrahedrite 1. On April 3rd, the reporter learned from the Bureau of Geology and Minerals of Henan Province that a scientific research team that the Bureau participated in discovered and named a new mineral in nature-empty tetrahedrite (English name: Kenorozhdestvenskayaite-(Fe)). Recently, with the official approval of the Naming and Classification Committee of New Minerals of the International Mineralogy Association, the complete specimen of new minerals will be collected in geological museum, China. Previously, the International Institute of Mineralogy announced that 2022 was the mineral school year, and dawsonite was fortunate to become theNo. 1 mineral in 2022.

According to reports, the empty tetrahedrite mineral is located in Yindongpo Gold Mine, Tongbai County, Henan Province, and is the ninth member of the international new mineral family belonging to Henan. After systematic mineralogical research on physical properties, chemical composition, crystal structure and spectral characteristics, the research team confirmed that it is a new tetrahedrite mineral that has not been discovered in nature.
The mineral specimen is gray-black, gray under reflected light, reddish brown with internal reflection, opaque metallic luster and black stripes; Brittle, irregular fracture; It is closely related to crimson silver ore, sphalerite, galena, wolframite and pyrite.
Empty tetrahedrite is the most abundant tetrahedrite in nature, with a silver content as high as 52.3%. As a common mineral in hydrothermal deposits, silver-bearing tetrahedrite not only has important economic value, but also its silver content is an index parameter of metallogenic temperature, which is of great significance to the study of deposit genesis.
What's more, the unique structure of dawsonite is praised as the unsolved mystery of tetrahedrite family by international colleagues, and its outstanding performance in catalysis, chemical sensing, photoelectric function and so on has become a hot spot in the research field of silver syndicate. As a mineral structure found in nature, the formation mechanism of tetrahedrite will provide a new reference for synthetic materials.
The discovery of new minerals is an important basic research work in the field of earth science and one of the important symbols of a country's mineralogical research level. The discovery of new minerals can not only increase the types of minerals in nature and enhance the international influence of mineralogy in China, but also provide new reference for human beings to understand and utilize natural minerals.
It is understood that the research was jointly funded by Henan Bureau of Geology and Mineral Resources, China Geological Survey, National Natural Science Foundation and Henan Provincial Financial Geological Exploration Project, and was jointly completed by the Third Institute of Geology and Mineral Resources of Henan Bureau of Geology and Mineral Exploration and Development, Tianjin Geological Survey Center of China Geological Survey, Nanjing University, Central South University, Beijing Institute of Nuclear Industry Geology and China Geo University (Beijing).

Dahe newspaper Henan video reporter learned that at present, there are 9 kinds of minerals in the international new mineral family belonging to Henan. Tongbai Mine (English name Tongbai Te Mineral Number: IMA1982-003) is produced in Liu Zhuang Mine and Weishan Mine (English name: Weishane Mineral Number: IMA1982-076) and Luanshi lepidolite Mine Number: IMA in Tongbai County, Henan Province.
Taiping Stone (English name: Taipingite-(Ce) mineral code: IMA20 18- 123a) is produced in Taiping Town, Xixia County, Henan Province, and Lingbao Mine (English name: Lingbao mineral code: IMA20 18-65438) is produced in Lingbao Gold Mine, Henan Province.
Empty zinc-silver tetrahedrite (English name: Kenargentete trahedrite-(Zn) mineral code: IMA2020-075) is produced in Yindongpo Gold Mine, Tongbai County, Henan Province, and empty iron tetrahedrite (English name: kenorozhdestvenskayite-(Fe) mineral code: IMA2022-00 1) is produced in Henan Province.
A new mineral in nature was discovered in Henan Province, which was named empty ferritetrahedrite. The reporter learned from the Bureau of Geology and Mineral Exploration and Development of Henan Province that a scientific research team involved in the Bureau discovered and named a new mineral-"empty tetrahedrite" in nature, which has recently been officially approved by the Naming and Classification Committee of New Minerals of the International Mineralogy Association.
According to the technical personnel of the bureau, the silver ore of empty tetrahedrite was found in Yindongpo Gold Mine, Tongbai County, Nanyang City, Henan Province, and it is the ninth member of the international new mineral family belonging to "Henan nationality". After systematic mineralogical research on physical properties, chemical composition, crystal structure and spectral characteristics, the research team confirmed that it is a new tetrahedrite mineral that has not been discovered in nature.

According to the observation and study, the mineral samples are gray-black, gray under the reflected light, brownish red in internal reflection, opaque in metallic luster, with black stripes, fragile, and closely associated with crimson silver ore, sphalerite, galena, empty tetrahedrite and pyrite.
According to reports, tetrahedrite is the most abundant tetrahedrite mineral in nature, with a silver content of 52.3%. More importantly, its special structure is praised by international peers as the unsolved mystery of tetrahedrite family, and its outstanding performance in catalysis, chemical sensing and photoelectric function has become a hot spot in the research field of silver clusters.
On April 3, the reporter learned from the Henan Bureau of Geology and Mineral Resources that a scientific research team involved in the bureau discovered and named a new mineral: empty tetrahedrite in Nature magazine. Recently, the mineral was officially approved by the new mineral nomenclature and classification committee of the International Mineralogy Association, and its complete specimen will be collected in geological museum, China. Previously, the International Mineralogy Association declared 2022 as the mineral school year, and in 2022, dawsonite became the 1 mineral.
According to reports, empty tetrahedrite is located in Yindongpo Gold Mine, Tongbai County, and it is the ninth member of the international new mineral family belonging to Henan. After systematic mineralogical research on physical properties, chemical composition, crystal structure and spectral characteristics, the research team confirmed that it is a new tetrahedrite mineral that has not been discovered in nature.
The discovery of new minerals is an important basic research work in the field of earth science, which belongs to the original scientific research results from 0 to 1 and is one of the important symbols of a country's mineralogical research level.
This research achievement is the concrete practice of our institute to actively implement the strategy of "strengthening the institute through science and technology", and it is an important achievement of our institute in deepening the Weishan urban metallogenic belt and carrying out basic research in recent years with the support of exploration projects and local scientific research projects of Henan Provincial Department of Natural Resources. This will further play the role of geological work in serving national economic and social development and ensuring the safety of resources and energy, and will also play a positive role in enhancing the scientific and technological innovation ability of our institute.
This research was completed by our institute in cooperation with Tianjin Geological Survey Center of China Geological Survey, Nanjing University, Central South University, Beijing Institute of Nuclear Industry Geology and China Geo University (Beijing). Major media such as Xinhuanet, Guangming.com, Zhongqing.com, Sohu.com, Tencent.com and Henan Daily reported the discovery of new minerals.
