武安市赵窑金矿矿化特征及成矿时代

Mineralization characteristics and age of Zhaoyao gold deposit in Wu’an city

武安市赵窑金矿是近几年围绕洪山岩体外围找矿又一成果,该矿产于洪山岩体西北部的二长闪长岩内,受紫山-鼓山及其次级断裂控制,具有多期次岩浆热夜活动的特点,根据矿石特征及成岩时代,推测为与白垩世洪山碱性杂岩体同源的岩浆期后热液矿床。

Zhaoyao gold deposit in Wu'an city is another achievement of prospecting around the periphery of Hongshan rock mass in recent years.The deposit is located in the monzodiorite in the northwest of Hongshan rock mass,controlled by Zishan Gushan and its secondary faults,and has the characteristics of multi-stage magmatic hot night activity.According to the ore characteristics and diagenetic age,it is speculated to be a post magmatic hydrothermal deposit homologous with the Cretaceous Hongshan alkaline complex.
