摘要:

铬铁矿是一种重要的战略性关键金属矿产,具有层状和豆荚状两种成因类型。研究表明,全球豆荚状铬铁矿主要分布在特提斯、古亚洲洋、环太平洋成矿域和冈瓦纳成矿域中,尤其是特提斯、古亚洲洋两大成矿域占主导地位。在该两大成矿域,境外已发现多处大型超大型豆荚状铬铁矿矿床,而在相同构造带的我国范围内,发现的铬铁矿矿床小而散。比较分析认为,我国铬铁矿资源潜力尚未充分挖掘,应增强我国铬铁矿找矿信心,聚焦在新疆萨尔托海、西藏雅鲁藏布江和班公湖—怒江、内蒙古二连—贺根山、甘肃大道尔吉等地区,改进找矿思路,优化找矿技术方法,加快钻探验证工作,尽快改变我国铬铁矿长期接近百分百依靠进口的局面。

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
