摘　　要：对矿床的成矿地质条件、控矿因素、地球物理和地球化学异常特征、找矿模式进行了归纳总结。该矿床受控于中元古界长城系渣尔泰山群阿古鲁沟组纹层状阳起石变质钙质粉砂岩、变质钙质粉砂岩地层 ,矿体一般呈层状顺层产出 ,与控矿地层产状一致。矿区内大面积分布的低阻、高激化和宽缓正磁异常区 ,与金化探异常相对应。初步认为该矿床属层控型金矿床。The metallogenic geological conditions and ore-control factors are systematically summarized, relationships between geophysical anomaly and gold geochemical anomaly in Alashan area of Inner Mongolia are analysed.The Zhulazhaga gold deposit in Inner Mongolia is controlled by the Meso-Proterozoic Aergulugou Formation of Chaertaishan Group consisting of metamorphic calcareous siltstone with the orebodies distributed along the sedimentary beds. It is considered that the gold deposit belongs to stratabound deposit.
