峪耳崖金矿是冀东地区一个典型的热液型矿床．硫、铅同位素组成表明太古宙变质岩是本区金矿的主要矿源层，是壳幔相互作用的结果．氧同位素表明水的来源以大气降水为主．在大气降水深循环过程中，金从围岩中多次萃取，频繁的岩浆活动使成矿元素进一步富集．成矿流体的组成、盐度、ｐＨ，Ｅｈ，ｆ（Ｏ２）表明金是以［Ａｕ（ＨＳ）２］－络离子形式迁移．由于物理化学条件的改变，导致了金的沉淀，在ＮＥ和ＮＮＥ向构造裂隙发育部位形成了金矿床
Yu ear cliff gold deposit is a typical hydrothermal type deposits in eastern Hebei. The composition of sulfur and lead isotopes shows that the Archean metamorphic rocks are the main source rocks of gold deposits in the area and are the result of crust-mantle interaction. Oxygen isotopes indicate that the source of water is mainly atmospheric precipitation. During the deep cycle of atmospheric precipitation, gold was extracted from the surrounding rock several times, frequent magmatic activities enrich the ore-forming elements. The composition of the ore-forming fluid, salinity, pH, Eh, f (O2) indicate that gold migrates as [Au (HS) 2] - complex ions. Due to the change of physical and chemical conditions, the precipitation of gold has led to the formation of gold deposits in NE and NNE tectonic fissures
