Au , Ag , As and Sb are typically indicative in the shallow part of No. 1 vein .

三级储矿构造主要发育于二级运矿构造两侧150m范围内，并控制了区内金矿脉的分布。

The gold-bearing quartz veins are controlled by the third level structures which distributed in 150m width scale both sides of the carrying ore structures .

南岭及日本等地一批与W、Sn矿产有关的高温矿脉的K-Ar年龄值大于岩体，这是氩聚效应的结果；

For the W-Sn mineralizations associated with hypothermal veins in Nanling district and some other places in Japan , their K-Ar ages are respectively larger in value than those of intrusives due to " Ar polymerizing effect " .

矿体赋存于太古代角闪质变质岩系，特别是变质闪长岩体周边及内侧，受NE、NNE向剪切破碎带控制，常在其傍侧断裂形成羽状矿脉。

Ore bodies occur in Archaeozoic hornblende metamorphic rock series , especially in the surrounding area and inner side of the metamorphic diorite , controlled by NE and NNE shear zone , and occur as feather veins in the side faults .

成矿分为两期：燕山早期形成NNE向矿脉，是矿区的主要成矿期；燕山中期形成NW-NNW向矿脉，是次要成矿期。

The mineralization can be divided into two stages , that is , the major mineralization of NNE veins at the early Yanshan period and the minor mineralization of NW-NNW veins at the middle Yanshan period .
