摘要
由于成矿作用的继承性、砂金的气液包体成分同原生的金十分相似.通过对珲春河砂金区十二个砂金样品包体成分及微量元素组成的研究,并和已知矿床自然金的包体成分数据进行比较,认为珲春河上游砂金来源于燕山期中低温超浅成岩浆热液金矿床.
Owing to the metallogenetic inheritance of placer gold and mountain gold, their liquid-inclusion composition are very similar.This paper deals with the inclusion composition and minor elements of 12 placer gold samples.Compared these samples with those native gold from USSR and Tuanjiegou gold deposits, the author considers that the placer gold in Upper Huenchun River originate from epithermal porphyry-type gold deposits of yanshan epoch.
