摘要
刘屯地区金地球化学异常与构造关系密切,构造对金成矿具有控制作用。20纪90年代以来,本区的采矿活动时断时续,至2011年上半年还有单位在此处开展采矿,因深部矿化减弱而终止。本文就刘屯地区地表和深部金矿化分布特征,阐述刘屯金矿采空区底部赋存金矿的可能性,预测其深部矿化特征。为较清晰显示矿区内地质特征,将全区分两个矿段:分别是金屯和刘屯矿段。近东西构造与北东向脉岩交汇部位是金成矿有利部位,赋存于近东西向构造内的矿体符合波形分布理论;根据矿体分布特征和元素地球化学特征在其深部还有赋矿可能性。
Gold geochemical anomalies and the structure has closely relationship in Liutun region, the struc-ture has a control function for Gold metallogenic. Since the 1990 s, the mining activities was on and off in this area, there were mining activitiesin the first half of 2011, it was terminated for deep mineralization de-crease. This paper explains gold possibility occurrence on the bottom that Liutun region distribution char-acteristics of the gold mineralization, and predict characteristics for deep mineralization. To show in the mine geological characteristics is clearly , it points the two ore-section： Jintun and Liutun ore section. The author thinks that it is gold mineralization favorable positions in intersection part of structure and vein rocks of north east, ore body conforms to wave distribution theory within the structure in nearly east-west; According to orebody distribution and element geochemical characteristics, it has the possibility of occurrence mineral in the deep.
