山东玲珑金矿地质特征及深部找矿潜力分析

根据玲珑金矿区的矿脉地质特征,归纳了上部矿体的赋存规律:靠近破头青断裂的矿脉规模储量较大,断裂的分支、复合、转折及交汇部位是成矿的有利部位,硅化、绢英岩化、黄铁矿化及蚀变叠加部位往往是最佳赋矿部位,中基性脉岩与矿脉的交汇部位地段矿体变大变富.对700m(-270m标高)以下的成矿有利地段(如175号脉群深部、36号脉群深部和玲珑断裂深部)进行了成矿预测.

GEOLOGICAL CHARACTERISTICS OF LINGLONG GOLD DEPOSIT,SHANDONG PROVINCE AND ORE POTENTIAL TO THE DEPTH

The paper deduces location regularity of gold ore bodies in upper position on basis of characteristics of ore veins in the Linglong mining district.Ore veins near Potouqing fractural zone are generally larger in size and reserve. Ramification,divergence,convergence and intersection of fractures are favorable for formation of gold ore.The most favorable location of gold ore occurs generally at silicification,phyllic alteration,pyritization and overprinting of alterations.And ore body becomes larger and richer where intermediate-basic dykes cut ore veins.According to the regularity favorable location for formation of gold ore(to depth of No.175 dyke swamp,No.36 dyke swamp and to that of Linglong fractural zone) are predicted.
