TECTONIC EVOLUTION AND THE GOLD DISTRIBUTION IN EASTERN HEBEI
-
摘要: 作者研究了冀东地区构造特征及其成生联系,建立了构造体系。根据构造运动时期的鉴定,研究了构造演化过程,探讨了矿化与构造之间的关系。根据同成矿构造体系展布特点,分析了金矿的分布规律和富集部位,并对典型矿区进行了同成矿应力场的模拟实验,预测了隐状矿体。部分靶区经过工程验证,获得很大的经济效益.Abstract: After a study of the structural features and their genetic relations in Eastern Hebei,the authors establish the structural systems of the region.A discussion of the tectonic evolution and their relation with mineralization is made on the basis of the determination of the age of the tectonic movements.It was found that the distrbution of the gold depesits is controlled by sysmetallogenic structural system,a system which was active during mineralization. At the same time,the authors carried out a model experiment of the synmetallogenic stress field of some typical gold areas for the prediction of the blind ore bodies,and achieved good success,yielding 22.72t of pure gold.
