| 摘 要： | 通过对区域地质背景、第四纪典型地貌及矿床地质特征等的研究，发现崩纳藏布砂金矿具有成矿时代新、成矿期短、物质来源多样性等特点。成矿过程明显具有2个阶段：早期可能与斑岩型铜－金－多金属矿床有关，含Au配合物近距离活化、迁移，在适宜的地方堆积成矿；晚期在原地吸收侧向补给的第四系含Au沉积物，次生富集成为富矿。

| Abstract: | Characters with new metallogenic epoch and short mineralization period and multiple mass sources are discovered by studing regional geolegic setting and geomorphologic landscope of Quatenary system and geological featues of mineral deposit in the gold placer of Bengnazangbu. The ore forming process can be diveded into two stages obviously. In the early course, it may be related with porphyry Cu Au multimetallic ore deposit, complexes of gold bearing transport and activate in short distance, pile up and form ore in the sure places. In the later course, it absorbed lateral feeder sediments of Quaternary system in the same places, enriched and formed rich ore finally. |
