Abstract: The fault structures of Fuxingchun gold deposit is well developed.The main ore-controlling structures is developed in the layered structures of the contact zone of marble of Zhenzhumen formation and schist of Dalizi formation,and northwestern,northeastern brittle shear fault zones.Rock structural plans have great impact on the rock mechanical property,so it can be divided into II,IIIand IV structural plane.The engineering geological petrofabric is divided into the Quaternary lax rock,harder-strong thin thick metamorphic rock,hard lump carbonate rock and hard lump volcanic rock in line with the lithology and rock mechanical property.The well developed bedding,foliation and joints,and poor integrity and engineering geological conditions of the rocks in the distribution area of hard lump carbonate rock group.Therefore,layers of the rocks should be studied in the future so as to deal with the engineering geological problems in the mining area.
