337 Uranium ore deposit lies to the east of the Xiazhuang orefield,and there are structural fracture groups with EW,NNE-trending,diabase and syenite vein with NW-trending in the deposit region.
337铀矿床位于下庄矿田东缘，区内发育近EW向、NNE向构造裂隙群及NW向辉绿岩和正长岩脉体，发育以碱性为主的多种围岩蚀变。

As for sulfur isotopic composition, the general feature of two types deposits is a single peak distribution. All δ〓s values of the ores are near zero. The difference of different deposits lies in that the δ〓s values (1. 8-5. 2‰) of LDT are of small positive value and are similar to that of the metamorphic rocks and dioritic porphyrites in the region while the δ〓s values of SDT are always near zero. Features above suggest that two types of deposits have closely genetic relationship to metamorphic and magmatic rocks.
硫同位素组成上，两类金矿床共同的特征是均具有明显的单峰塔式效应，且δ〓S值均位于0值附近不大的变化范围内；不同的是，近程式金矿的δ〓S平均值均接近于0，与该类金矿具密切成因联系的岩体的δ〓S值也接近于0值，而远程式金矿的δ〓S平均值均为小的正值，变化范围为1.8～5.2‰，区内太古代变质岩及矿区内闪长玢岩脉的全岩δ〓S值位于这一区间内，反映了远程式金矿床其成矿物质不仅来源于重熔岩浆，同时还可能部分来源于变质岩围岩。
