克鲁伦—额尔古纳拼合地块有色金属矿产成矿条件及找矿方向探讨

Discussion on the mineral formation condition and exploring targets of nonferrous metal in Clulun-Erguna integrated block

克鲁伦—额尔古纳拼合地块位于中国、俄罗斯、蒙古国三国边境地区,集中分布有几十处有色金属矿床,其找矿前景和潜在的经济资源价值十分巨大,是世界级有色金属成矿带。本文通过对该区地质背景、成矿条件和控矿因素分析,指出寻找火山岩型有色金属矿床的找矿方向,并预测中俄两国北东向边境线两侧和中蒙两国北东向边境两侧将是未来重点找矿靶区。

The Clulun-Erguna integrated block lies in the border area among China, Russia and Mongolia. There area some dozen of nonferrous metal deposits concentrated in the block. It has light prospecting future and huge potential economic value, so this is a key metallogentic belt in the world. Through analyzing geological setting and mineral formation condition, the paper discusses the factors that control the defining the prospecting type of deposit. Meanwhile pointing out that the border area among China, Russia and Mongolia will be the key exploring targets in the future.
