摘　　要：以玲珑金矿田阜山金矿区为实测地区 ,研究了胶东构造岩浆活化区玲珑 焦家式金矿的矿源岩系 ,对 2km2 内矿源岩的构造变形岩相形迹进行 1∶2 0 0 0填图。在这一研究工作积累的基础上 ,提出矿化趋势度 (MTD)的概念并完成阜山金矿区矿化趋势度的分布图。矿化趋势度的概念及其填图研究方法对于探讨将成矿模型转化为找矿模型 。Taking the Fushan gold district in Linglong gold mine as an example, this paper studied the ore source rocks of the the Linglong-Jiaojia type gold deposits in structural-magmatic mobilized area of Jiaodong and performed 1∶2 000 mapping of tectono-deformation facies of ore source rocks in an area of 2 km 2.Based on the above work, the authors put forward the concept of mineralization trending degree(MTD) and completed the distribution map of MTD in the Fushan gold district. The concept of MTD and the method for mapping are of great significance and practical prospect in converting a metallogenic model into an ore-prospecting model and in finding much more quantitative ways for ore-hunting work.
