摘　　要：通过对白象厂金矿的区域地质概况、矿区地质特征及控矿因素的分析研究,认为,白象厂金矿产于二长斑岩与玄武岩接触带上,局部赋存于二长斑岩与大理岩、玄武岩与大理岩的接触带上,呈脉状,似层状透镜状产出。矿化受构造及岩浆岩联合控制。矿床为构造破碎斑岩蚀变型金矿床。根据该矿床的控矿规律,认为沿金矿化带的走向和倾向方向上可能找到厚大、品位高的金矿体或金的次生富集体。By the analysis on regional geological background, ore field geological character and ore controlling factors, the author considers that the Baixiangchang gold deposit occurs on the contact zone of monzonitic porphyry with basalt, partly occurs on the contact of monzonitic porphyry with marble or the contact of basalt with marble in form of vein or stratiform lens. The mineralization was jointly controlled by structure and rocks. The deposit is a structure zone porphyry alteration type gold deposit. According to the ore controlling regularities of the deposit, it is believed that there is a possibility to find big and high grade gold orebodies or secondary gold enrichment along the striking or dipping of the gold ore zone.
