| 中文摘要: |
| 小湾钨锡矿点综合以往成果资料，结合本次工作，初步了解矿体分布规律、形态、品位变化及构造特征，初步圈出5处W、Sn综合异常范围，经工程印证，控制5条近平行的NE向含矿石英脉带，证实属矿致异常，采样分析，厚度及品位均达到工业要求。研究小组综合利用调查研究-学术论文参考等多技术手段，并探讨矿床的成因:认为该矿点是与燕山早期黑云母花岗岩有关的岩浆期后热液矿床，围岩蚀变主要有云英岩化、钠长石化，二者蚀变与钨锡成矿关系密切；另外，野外露头对比，在成矿后期构造叠加部位矿化愈好。建议下一步找矿方向主攻类型石英脉型、蚀变花岗岩型钨锡多金属矿，开展地-物-化-遥成果资料二次利用，基于GIS技术进行优选找矿靶区。 |
| 英文摘要: |
| Based on the previous results and data，combined with this work，the distribution law，shape，grade change and structural characteristics of the ore body are preliminarily understood，and five W and Sn comprehensive anomaly ranges are preliminarily circledIt is confirmed by engineering that five nearly parallel NE-trending ore-bearing quartz veins are controlled，which is confirmed to be ore-induced anomalySampling analysis，thickness and grade meet industrial requirementsThe research team comprehensively utilized multiple technical means such as investigation and research-academic paper reference，and discussed the genesis of the depositIt is believed that the ore spot is a post-magma hydrothermal deposit related to the early Yanshanian biotite graniteThe wall rock alteration mainly includes greisenization and albitization，and the alteration of the two is closely related to tungsten-tin mineralizationIn addition，the comparison of field outcrops shows that the mineralization is better at the structural superposition site in the later stage of mineralizationIt is suggested that the next prospecting direction should focus on quartz vein type and altered granite type tungsten-tin polymetallic deposits，carry out the secondary utilization of geological-physical-chemical-remote sensing data，and optimize the prospecting target area based on GIS technology |
