山东黄埠岭金矿10号矿脉地质特征及矿化富集规律

10号脉是山东黄埠岭金矿区内的主要工业矿脉之一,产于玲珑花岗岩岩体中,受F10断裂构造控制。矿体呈柱状、脉状或透镜状产于矿脉内。矿石组成矿物有黄铁矿、自然金、银金矿、黄铜矿及石英等,矿石以交代溶蚀结构和脉状角砾状构造为主。矿化分4个阶段,含矿率为40%。矿化富集具有尖灭再现、侧伏和多期多阶段成矿等规律。10号脉深边部仍有成矿找矿远景。

Geological characteristics and mineralization enrichment regularity of the 10th ore vein in Huangbuling gold deposit of Shandong

The 10th ore vein found in Linglong granite is one of the most important industrial ore veins of Huangbuling gold deposit,controlled by the F10 fracture.Ore bodies were prismatic,vein or lenticular in shape.The ore was composed of pyrite,native gold,electrum,chalcopyrite and quartz,etc.The minerals are mainly metasomatic dissolution and veinlike breccia in structures.There are 4 steps in mineralization,and the ore-bearing rate is 40%.The enrichment has some regularities,such as thinning out and reconstruction,lateral trending and multi-period mineralization.The deep and edge part of the 10th ore vein is greatly perspective in prospecting.
