摘　　要：为了查清大庙子—板庙子金矿化区内矿体赋存条件,指导工程布置,从区内成矿背景出发并在分析地层、构造、岩浆岩的基础上,研究区内控矿条件和找矿标志,从而进行矿体预测。研究表明大庙子—板庙子金矿化区内金矿体以石英脉型为主,矿体的产出受东西向挤压破碎带控制,钾质花岗岩和闪斜煌斑岩是矿体的主要围岩;在此基础上,共圈定靶区5处。For making clear the orebody conditions and advising the construction settling in Damiaozi-Banmiaozi district,based on analyzing the stratigraphy,tectonics and magmatite,the authors research the ore-controlling conditions and propecting marks,and predict the orebody. The study shows that the gold quartz vein is the largest orebody which was controlled by E-W extrusion fracture zone. The kaligranite and spessartite are the largest wallrocks. Five prospecting targets in the Damiaozi-Banmiaozi district are delineated.
