山东招远平度断裂破碎带蚀变岩型矿石类型划分

山东招远-平度断裂破碎带蚀变岩型部分矿石类型划分与实际生产工作相脱离,该文在前人分类的基础上,提出新的定名方案,将矿石类型初步划分为含金蚀变花岗岩、含金黄铁绢英岩、含金硅化黄铁绢英岩、含金硅化岩、含金硅质石英脉和细脉含金硫化物。该划分方案使每一种矿石类型与金品位高低和SiO2含量的多少相联系,并作为找矿标志,操作性强,有利于矿山生产,加快了探矿进度。

Division of Altered Rock Type Ores in ZhaoyuanPingdu Faulted and Shattered Zone in Shandong Province

Division of altered rock type ores in Zhaoyuan-Pingdu faulted and shattered zone in Shandong province can not meet the demand of factual production work.On the basis of the former information,a new naming method has been put forward.The altered rock type ores in this area can be divided into alteration granite including golden,beresite including golden,silicification beresite including golden,silicification rock including golden,silicon nature quartz vein including golden,and the stringer vein contains the golden sulfide.The division method can combine every type of ores with gold ore grade and the content of SiO2 together,and regarded as a symbol of ore exploration.It is easy to conduct,favorable to production work,and speed up ore prospecting.
