摘　　要：基于野外调研 ,对赤峰红花沟金矿田的控矿构造及其矿体、岩体与地层之间的地质关系进行深入研究 ,提出金矿化发生在燕山早期 ,对燕山早期岩石化学与矿石氢氧同位素进行系统分析 ,得出本区矿床成因为重熔型成因 ,其成矿热液为原生岩浆水 ,后期有少量的大气降水加入。Through the study on the tectonic system controlling orebodies and the geological connections between orebody, magmatic body and strata, the authors put forward that the Early Yanshanian was the dominating mineralizing period of Au. As viewed from the petrochemistry of Early Yanshanian and hydrogen-oxygen isotopic characteristics of orebodies in the Honghuagou gold orefield, it is considered that the origin of the Honghuagou gold orefield is of the remelting type with magmatic water as the dominant mineralizing solution with some meteoric water involved at later stages.
