招掖地区郭家岭花岗岩控矿的几点证据及找矿指示意义

Ore-controlling evidence and ore prospecting significance of Guojialing granodiorite in northwest Jiaodong peninsula

尽管胶西北郭家岭花岗闪长岩与金矿化存在着密切的时空关系,但不同学者对二者间的物质联系尚存在歧义。文中汇集了招掖地区近年来部分找矿勘查成果,结合笔者工作认识,对郭家岭花岗闪长岩的控矿作用给予了客观评述。提出了焦家—玲珑式金矿床受郭家岭花岗闪长岩体接触带形态和断裂构造蚀变带联合控制的论断。在此基础上,对本区以往找矿工作思路进行了反思,给出了本区深部及外围找矿的新思路。

Although it has been recognized that the time-space relationship between Guojialing granodiorite and gold mineralization is very close in the northwestern Jiaodong peninsula, the metallogenetic origin is still a considerable contradiction. This contribution collected some of advance on ore-finding and prospecting within the recent years, combining with the recognition of the author about the region, it objectively remarked the ore-controlling significance of Guojialing granodiorite, and concluded that the cooperation of the two ore-controlling factors , one of which is the morphology of the contact zone between Linglong granite and Guojialing granodiorite, another one is the fault altered zone, controlled the Jiaojia-Linglong style gold deposit. Finally the article reviewed the ore-finding work in the past twenty years, and pointed out that it was possibly just the traditional ore-finding recognition that led to the failure exploration, furthermore it gave a kind of new path for successful ore-finding exploration in the deep and surround of the ore area.
