Abstract:

Chromite is an important strategic metal mineral, which has two genetic types: stratiform and podiform. The results show that the podiform chromite is mainly distributed in the Tethys, PaleoAsian Ocean, Pacific Rim and Gondwana metallogenic regions, especially the Tethys and PaleoAsian Ocean metallogenic regions. In these two metallogenic regions, many large to super-large podiform chromite deposits have been found abroad, while in the same tectonic belt within China, the chromite deposits found are small and scattered. The comparative analysis shows that the potential of chromite resources in China has not been fully tapped, and the chromite prospecting confidence should be enhanced, focusing on the areas such as Sartokay in Xinjiang, Yarlung Zangbo River and Bangong Lake-Nujiang River in Tibet, Erlian-Hegenshan in Inner Mongolia and Dadaoerji in Gansu Province, so as to improve prospecting ideas, optimize prospecting technology and methods, and speed up drilling verification. End the long-term situation of totally relying on import from abroad as soon as possible.

Key words: chromite, strategic mineral, mineralization pattern, prospecting target, resource potential
