摘　　要：讨论了罗山金矿煌斑岩的地质特征及其找矿意义。认为矿区内煌斑岩控制了金矿体的空间分布，为成矿期脉岩，而不是前人所厘定的成矿后脉岩；煌斑岩极有可能提供成矿过程所需的部分物质、热能来源及场所，是重要的找矿标志。The geological feature of lamprophyre in Luoshan Gold Deposit and its significance to oreprospecting are discussed,believing that the lamprophyres (within the mine area) which have controlled the spatial distribution of gold orebody are vein rocks occurred in mineralization epoch not vein rocks occurred after mineralization epoch as predecessors concluded,and moreover,they are quite possible to provide mineralization with a part of materials ,thermal energy and place,thus they are important mark of oreprospecting.
