| 摘 要： | 对娄里金矿中金元素的赋存状态、产出特征进行的分析研究显示，娄里金矿床中金主要以细粒（5~20 μm）自然金为主分散浸染于蚀变较强的凝灰岩和粗面岩裂隙中.金在石英脉和褐铁矿中赋存比例仅为12.5%，远低于片理发育的蚀变凝灰岩.因此娄里金矿的找矿标志有其特殊性.结合野外已知金矿体周边岩性分布特征，提出在岩石片理化及层间裂隙发育处，且出现含霓辉石细粒正长斑岩地段应是下一步找矿重点区域.

| Abstract: | Study on the characteristics of Louli gold deposit indicates that the Au element, mainly occurring as fine-grained natural gold, is dispersively disseminated in the fissures of strongly altered tuff and trachyte. The proportion of gold in quartz vein and limonite is 12.5%, much less than that in the altered tuff with developed schistosity, showing the particularity of prospecting indicators of the deposit. Considering the lithological distribution characteristics around the known gold orebodies in the field, it is believed that the developed zones of schistosity and interlayer fissures together with the aegirine-augite-bearing fine-grained orthophyre should be the focus of further exploration. |
