This paper discusses the possible relationship between ore mineral′s magnetic characteristic and gold enrichment.
作者认为矿石矿物的磁性特征与金富集可能有成因上的联系 :(1)黄铁矿与磁黄铁矿、黄铜矿和方铅矿等相比 ,以极微弱的反铁磁性 ,不易受微弱外电和磁场的影响 ,在电性和晶体结构方面更具稳定性等特征 ,且易吸附纳米级金粒 ;(2 )压力可使矿石矿物出现压磁效应 ,矿石矿物磁性矢量产生各向异性 ,金粒易在磁矢量加大方向发生富集 ;(3)颗粒细小、受多次压力作用、温度接近居里点等因素都能使矿石矿物的磁性加强 ,形成金富集的有利条件。
