| 摘 要： | 华蓥山Ｓｒ成矿带是我国最重要的Ｓｒ矿带。通过对该成矿带典型矿床的Ｓｒ、Ｈ、Ｏ、Ｓ同位素特征的研究，指出该Ｓｒ成矿带的Ｓｒ主要来自含矿围岩，成矿流体的水源为大气降水和地层建造水的混合流体，Ｓ源为嘉陵江组地层，在矿床稳定同位素特征及成矿物质来源研究的基础上，结合其他的矿床地质特征，指出该Ｓｒ成矿带中分散元素Ｓｒ在沉积－成岩期发生了初步富集，后经热卤水及动力改造富集成矿，属沉积－热卤水脉动力改造成因矿床

| Abstract: | The Huayingshan Sr mineralization belt is the most important Sr mineralization belt inChina. Its isotopic characteristics of Sr, H, O, and S are dealed with. It is indicated that theSr was derived from ore-bearing strata, the mineralizing fluid was a mixture of meteoric waterand formation water, and the sulfur originated from Jialingiang Formation. In summary, theHuayingshan Sr deposits belong to hot sedimentary brine and dynamically reworking deposits.Its mineralization is related to originally sedimentary-diagenetic enrichment and later hot brine-dynamic reworking. |
