玲珑金矿田位于胶东北西部，招掖金矿带的东端，47#脉为矿田内的三级构造，是主要的容矿、控矿断裂，47#脉的支脉是三级的一些派生断裂，主要是容矿构造，它们受一、二级断裂的控制，矿脉和矿体在时间和空间上呈规律性分布，且成矿作用具有多期次性，主要成矿阶段是金-石英-黄铁矿阶段、金-多金属硫化物阶段两个阶段；同时脉岩与矿体的形成关系密切，也是主要的找矿标志。

With the implementation of exploration engineering in the deep zone of the middle area, the Linglong gold mine faces risk of resource reserves and ore grade decreasing sharply. Through the comparative analysis of resources assessment and cost, new useful ways to solve the problem are presented. Make full use of the low grade ore, and set up a residual high grade residual ore recovering team with experience and skill of private mining to exploit more high grade ore. In practical applications, the scheme improved the output of gold, reduced the risk and cost, then obtained remarkable economic effects. So it can provide reference for other gold mines in China.

Linglong gold ore field is the resources crisis mines,expanding the resources reserves is urgently needed.Jiuqu ore block located in the eastern part of exquisite gold mine field,is the support and exquisite gold production of the main mining area.There are dozens of ore block in different size,which are crisscross,bringing difficulty for deep ore prospecting.According to these vein spatial distribution,branch complex relationship,the geological feature of the No.5 vein department in Jiuqu ore block is analyzed,also its metallogenic regularities is summed up.Based on this,we constantly get good production achievements,significantly increase the industry and prospective geological reserves,and provide resource for the continued development of the Linglong gold mine.

Mineral vein of Dongshan deposit in Linglong gold field is numerous,the relation of mineral vein is complex and mineral vein have the obvious phenomenon of convergence,separation,reunion.Through the research of distributed regulation,geology characteristic,country rock alteration,mineral vein with rock vein of vein No.18,47,50,176N,48,as well as comparisons of the complexion of space distribution,occurrence,and grade variation Metallogenesis is summarized,finding out the mineral enrich to gather the beneficial part,which provides geological references for exploration.
