摘　　要：黄铁矿是山东界河金矿的主要载金矿物之一,自然金常赋存于黄铁矿的晶体裂隙及晶隙间。通过对黄铁矿的晶体形态、物性标型特征的空间变化规律以及黄铁矿主成分的研究,表明黄铁矿的含金性与其粒度、晶形、产状、杂质元素和某些物理性质有关,从中可提供许多重要的找金信息。借助理论推导公式计算Ⅰ号矿体向深部至少延深400 m,总延深达-946 m,这对于矿区深部进一步找矿具指导意义。Pyrite is one of the main Au-carriers in Jiehe gold deposit. Natural gold occurs in fissures or interstial of the pyrite and quartz crystals. The results of the study on spatial distribution regularity of crystal shapes, physical typomorphic characteristics and essential composition shows that the feature of the gold-bearing pyrite is related to the grain size, crystal form,attitude,impure element and some physical property of the pyriye. The feature has provided many important ore informations. By academic formula the author computered that ore body Ⅰ at least extend to depth of 400 meters （-546--946m . This informations has important significance for further exploration of the deep gold depost.
