| 摘 要： | 热液矿床原生晕以往都被视为正晕。近年来虽已提出原生晕包括正晕和负晕,但由于多种原因,到目前为止,原生晕的研究几乎仍局限于正晕。作者为研究矿质来源,对一批与岩浆活动有关的斑岩型、夕卡岩型和脉型等大型热液矿床进行了研究,发现在矿床的正晕外围都有成矿元素负晕。根据研究结果还提出了热液矿床成矿元素地球化学场系,即以矿体为中心,向外依次为矿化场、正晕场、降低场和背景场。

| Abstract: | Primary haloes of hydrothermal deposits were considered as positive haloes before. Although it has been recently suggested that the primary haloes could be positive and negative, almost all the research work on primary haloes has still focused on positive |
