摘　　要：通过地质调查,查明红土岭矿区中深部金矿体的3种产出方式:a)地表露头矿的深延部分;b)隐伏于地表及浅部无矿段的深部;c)赋存于隐伏矿脉之中。通过对矿床的矿石物质组成、结构构造、金的赋存状态和成矿机理的研究认为,矿床属中低温热液脉状金矿床。指出S884-①、S1002-①号矿体的中深部及S899、S884、S881、S1002矿脉的中深部具有良好的找矿前景。Investigation reveals that the ore bodies in the deep part of Hongtouling gold deposit occur in three types: 1) deep-extended part of the outcrop ore bodies, 2) concealed below shallow parts without ore bodies, 3). hosted in concealed veins. According to the study on the mineral components, texture and structure, Au-hosted situation, and ore-forming mechanism, it is suggust that Hongtouling Gold Deposit should be the low-mesothermal hydrothermal vein ore deposit. And also the mid-deep parts of 884-① ore body, S1002-① ore body and ore veins of S899, S884, S881, S1002 have good prospecting future.
