摘要
冀东太古界迁西群金厂峪组斜长角闪岩与金矿关系密切.其原岩可能为海底基性喷出岩.本区岩石Au的丰度、Au的溶滤试验、同位素和微量元素的特征研究结果表明,金厂峪组斜长角闪岩是金的矿源层.
Palagioclase hornblendite of the Archeozoic Qianxi Croup Jincahngyu Formation is closely associated with the gold mineralization in eastern Hebei province. Possibly the primary rook of palagioclase hornblendite is submarine basic extrusive rock. Results from a study on the abundance of the gold in rocks of this area, lixiviation test of gold, and features of isotopes and trace elements indicates that the palagioclase hornblendite of the Jinchangyu Formation is the source bed of the gold mineralization.
