| 中文摘要: |
| 瓦图科拉金矿为典型的浅成低温热液型金多金属矿床，矿石类型复杂，钼与金密切伴生，呈黑色胶体状发育。本文系统采集了瓦图科拉金矿床的钻孔及地表样品，通过岩矿鉴定、电子探针测试及电镜扫描等手段，分析其矿石特征、矿物形态及钼矿物的赋存状态，首次明确该地区与金密切伴生的钼为胶硫钼矿，并结合矿床类型推测了该钼矿种的形成过程。该矿种的厘定为瓦图科拉金矿后续进一步提升综合利用价值提供充足依据。对该地区金矿成因分析具有指示意义，为矿床深部勘查提供科学依据，对矿产勘查工作的规划具有重要的指导意义。 |
| 英文摘要: |
| The Vatukola gold deposit is a typical epithermal gold polymetallic deposit with complex ore types.Molybdenum is closely associated with gold and develops in a black colloidal form. The samples were collected fromdrilling and surface of the Vatukola gold deposit systematically and its ore characteristics, mineral morphology, andoccurrence of molybdenum minerals were recognized through petrography and mineral identification, electron probe, and electron microscopy scanning. For the first time, it was determined that molybdenum, which is closely as.sociated with gold in the area, is a sulfide molybdenum ore. What's more, the formation process of the molybdenumdeposit were inferred with the ore type. The determination of this mineral provides sufficient basis for further en.hancing the comprehensive utilization value of the Vatukola gold deposit in the future. The analysis of genesis ofgold deposits in the region has indicative significance, providing a scientific basis for deep exploration of mineral de.posits and important guiding significance for the planning of mineral exploration work. |
