【摘要】Dayingezhuang Gold Deposit is located in the middle part of Zhao-Ping Fault zone.The alteration of the deposit is distinct in zonation with Dayingezhuang fault being an ore-conducting fault that has an evident control of the spatial distribution of the orebody and its lateral prostration.Chemical analysis of the altered rock indicates that Si in beresites and sericitic alteration cataclasite partly comes from K-feldspathized granite,and there is significant Fe,Mg and Mn association in
K-feldspathized
granite,sericite
quartz
cataclasite
and
beresite.Au,Ag,As,Mo,Bi,B,Ba,Rb and Sr are also common and accumulational in beresite and sericite quartz cataclasite,while elements like Mn,Co,Ni, Cr and so on are significantly enriched in part of metamorphic rocks of Jiaodong Group near Zhao-Ping Fault.The elec-trolysis mineralization mechanism of Dayingezhuang Gold Deposit can be summarized as such:the gold orebodies con-stitute the cathode of\reduction of SO2 -4 ,crys-tallization reactions of sulfide minerals and gold minerals,and water-rock interaction in connection with sericitic altera-tion;the carbonatization and ferritization altered rocks constitute
the anode of\electrolytic bath\electrol-ysis mineralization mechanism will help understand the mineralization and the indicators for alteration rock deposits in Northwest Jiaodong Region from a new perspective.%大尹格庄金矿床位于招平断裂带中段，矿床蚀变分带明显，大尹格庄断裂为一条导矿断裂，对矿体空间分布及侧伏具有明显的制约。蚀变岩岩石化学分析显示，黄铁绢英岩和绢英岩化碎裂岩中的Si有一部分来自钾长石化花岗岩，钾长石化花岗岩、绢英岩化碎裂岩和黄铁绢英岩中均有Fe、Mg、Mn的显著带入。在绢英岩化碎裂岩和黄铁绢英岩中普遍而显著聚集的元素还有Au、Ag、As、Mo、Bi、B、Ba、Rb、Sr等，在靠近招平断裂带的胶东群变质岩局部则有Mn、Co、Ni、Cr等元素的显著聚集。大尹格庄金矿床的电解成矿机理可以概括为：金矿体构成了“天然电解池”的阴极，在阴极附近发生的主要反应是SO2－4的还原与黄铁矿等硫化物矿物和自然金等金矿物的结晶反应，及绢英岩化水岩反应，以碳酸盐化和褐铁矿化为代表的蚀变岩构成了“天然电解池”的阳极。电解成矿机理有助于从一个新的视角认识胶西北蚀变岩型金矿床成矿作用及有关的找矿标志。 【总页数】4页(10-13)
