摘要
小锡板砂金矿床是冲、洪积型砂金矿，与地貌地凹处、河流的分布密切相关．砂金产出在褐色的砂砾层其中砾石大小，含砾率与砂金品位成正比，砂金产出与基底型态密切相关．砂金物质来源主要是矿源、岩源、次生源补给．
Xiaoxiban Sandgold deposit is the alluvial and diluvium Sandgold ores.The sandgold deposit is ralated to the lanforms depression and the river destribution.The sandgold producing area is in the brown sand and gravel layers.The sandgold grade is in direct proportion to the gravel size and the ratio of the gravel.The sandgold producing area is ralated to the base form.The major sandgold substance origin is in the ore bed and rock.
