Boron nitride minerals are officially named as Qingsong Mine by international organizations.

The **Journal of Mineralogy**, published in August, announced that a new boron nitride (BN) mineral discovered by Chinese and international researchers has been officially recognized by the International Mineralogical Society. The mineral has been named *Qingsongite* in honor of Fang Qingsong, a distinguished researcher from the Chinese Academy of Geological Sciences (1939–2010). This discovery marks a significant milestone in mineralogy, as it is the first BN mineral to be formally named and recognized on an international scale. In the context of the Robussa chromite ore deposit, this new mineral was identified alongside other rare materials, highlighting the geological complexity of the region. Notably, the discovery also includes the first diamond found within the Lobusha chromite ore, further emphasizing the importance of this site for mineralogical research. In recent years, Dr. Yang Jingyu, a researcher at the State Key Laboratory of Continental Tectonics and Dynamics at the Chinese Academy of Geological Sciences, has led collaborative efforts with international teams to explore diamonds within 10 ophiolites across five different orogenic belts worldwide. These studies have revealed intriguing findings, including diamond inclusions in coesite and antimony ores. Among the most fascinating discoveries are ultra-high-pressure minerals such as titanium nitride (TiN) and boron nitride (BN), which are formed under extreme conditions deep within the Earth's mantle. Composition analysis of *Qingsongite* shows a high concentration of boron (48.54%) and nitrogen (51.46%), confirming its chemical formula as BN. It crystallizes in a cubic structure, making it one of the rarest forms of boron nitride ever documented. The mineral is extremely small, with the largest particle measuring only 1 micrometer, while most particles are nanoscale in size. It is encapsulated within micro-scale coesite and kyanite, indicating its formation under ultra-high pressure conditions. Experimental data reveal that *Qingsongite* formed at temperatures exceeding 1,300°C and pressures ranging between 10–15 GPa, corresponding to depths greater than 300 km. These conditions suggest that the mineral originated deep within the Earth’s mantle and was later brought to the surface through tectonic activity. The discovery of *Qingsongite* and other ultra-high-pressure minerals, such as diamonds, in various orogenic belts around the world provides compelling evidence that the mantle beneath oceanic spreading ridges can transport deep-formed minerals and associated chromite upward into the upper crust. This finding offers a fresh perspective on the global distribution of chromite deposits and challenges existing theories about the formation mechanisms of ophiolites and oceanic crusts. It opens new avenues for understanding deep Earth processes and their impact on surface geology.
