摘要
棉花洲矿区位于胶东隆起带 ,昆嵛山复背斜与 NE、NNE向断裂构造的复合部位。NNE向左行压扭性断裂是主要控矿构造 ,已发现金矿脉 8条。赋矿围岩为鹊山中粗黑云母花岗岩 ,金与黄铁绢英岩蚀变关系密切 ,为中低温热液多金属硫化物石英脉型金矿床 ,成矿温度为 1 60～ 370℃。可划分为 4个成矿阶段 :黄铁矿 -石英 ;金 -黄铁矿 -石英 ;金 -多金属硫化物 -石英 ;石英 -碳酸盐。根据找矿标志确定有利的成矿部位是已知矿脉 (体 )的深部及两侧 ,辛安河流域。
Mianhuazhou mining area is located in the composite area of Kunlun Mountain anticlinorium and NE NNE trending faulted structure in the mole track, eastern Shandong. Left handed compresso fault trending NNE is the main ore control structure, which has eight known gold veins. Hosted wallrocks are Queshan coarse biotite granite and gold is closely related to the pyritic phyllic alteration. Thus it is a meso epithermal poly metallic sulfide quatz vein gold deposit. The mineralized temperature is 160~370℃. It can be divided into four mineralized stages: pyrite quartz, gold pyrite quartz, gold polymetallic sulfide quartz, quartz carbonate. According to prospecting criteria, it is defined that the favorable mineralized places are two sides and deep of the known vein , Xin ′an river basin and Liujiakuang nearby.
