中国关键金属典型矿集区元素超常富集研究进展

关键金属逐步成为国家经济发展、高新技术产业革命的重要战略资源，其元素富集统计及其机制的研究一直是研究的热点。本文针对大兴安岭成矿带、江南古陆矿集区、黔渝湘矿集区、川西造山成矿带和新疆西部矿集区进行对比研究，选取了Cd、Rb、Ta、Nb、W、Co、Zr、Hf和Cr这9中代表性的关键金属元素，其中大兴安岭成矿带中Cd、Cr较为富集；江南成矿带Cd、W、Cr较为富集；黔渝湘成矿带Cd、Rb、Nb、Co较为富集；川西造山成矿带Cd、Nb、Co、Zr较为富集；新疆西部矿集区W、Co、Zr较为富集。这些关键金属富集通常有多重载体矿物，这些矿物之间关系复杂多样，均超过伴生组分综合评价品位，可为工业生产提供重要的潜在资源，但仍需针对关键元素的来源、迁移和聚合过程进行更为深入的研究和探讨，这样能更好地理解关键金属沉淀的主导机制和关键控制因素。

Research progress on supernormal enrichment of rare elements in typical ore-gathering areas of key metals in China

Key metals have gradually become important strategic resources for national economic development and high-tech industrial revolution, and the study of their element enrichment statistics and its mechanism has always been a hot topic.This article in view of the greater hinggan mountains metallogenic belt, the jiangnan ancient land ore concentration area, guizhou yuxiang ore concentration area, western sichuan orogenic metallogenic belt, and western xinjiang ore concentration area comparison research, select the Cd, Rb, Ta, Nb, W, and Co, Zr and Hf, and Cr in the 9 typical key metal elements, the greater hinggan mountains metallogenic belt in the enrichment of Cd, Cr, relatively;The Cd, W and Cr of jiangnan metallogenic belt were enriched.Cd, Rb, Nb and Co were enriched in the metallogenic belt in guizhou, chongqing and hunan.Cd, Nb, Co and Zr were enriched in the orogenic metallogenic belt in western sichuan.W, Co and Zr are concentrated in the western xinjiang.These key metal enrichment usually have multiple carrier minerals, the relationship between mineral complex and diverse, comprehensive evaluation grade than associated components, can provide important potential resources for industrial production, but still need to be based on the source, migration, and polymerization process of the key elements in more in-depth research and discussion, in this way can better understand the key leading mechanism and key controlling factors of the metal deposition.
