| 中文摘要: |
| 国外部分地区地质研究程度极低或空白,快速、简单、准确圈定砂金靶区尤其重要。德雷沃河砂金开采区东西长为860 m,南北宽达600 m,面积约0.516 km2,砂金品位5 g/m3,储量达16.5 t。系统探索研究德雷沃河河源、上游、中游、下游和河口等不同河段地形地貌和水动力条件,砂金矿的富集规律、分布特征、成因类型、形态类型、开采方式和找矿远景,为下一步探采砂金和岩金提供基础数据、思路、方法和工作准则。 |
| 英文摘要: |
| The degree of previous geological research in some areas abroad is extremely low or blank, and it is especially important to quickly, simply and accurately circle the sand target area. This paper analyzes the evolution law, present situation of placer gold mining and metallogenic characteristics of the terrace in the upper reaches of the Derevo River. The present mining area is east-west 860m, north-south 600 m,0.516 km2,grade 5g/m3,reserves 16.5 t. To explore and study the topography, geomorphology and hydrodynamic conditions of different river sections, such as river source, upstream, middle, downstream and estuarine, the enrichment law, distribution characteristics, genetic types, morphological types, mining methods and prospecting prospect of alluvial gold, and provide basic data, ideas, methods and working criteria for the next exploration of alluvial gold and rock gold. |
