摘要
本文以伸展构造理论为基础，探讨了冀东幔枝（变质核杂岩）构造的成矿控矿作用，讨论了冀东三种主要的成矿作用类型，并重点阐述了盖层金矿的特征，指出了新一轮找矿方向。
On the basis of extensional tectonic theory in this paper, discuss the ore-forming and orecontrolling of mantle branch (metamorphic core complex) structures in East Hebei, as well as three types major mineralozation, and studies mainly characteristics of gold deposits in covering strata. Finally, the authors suggest new exploration direction.
