| 摘 要： | 闪锌矿是在许多矿床中最常见的矿物.闪锌矿的Cd、Fe含量与矿化阶段关系的研究,可以推断矿液演化史和矿床形成环境变化史.对矿床评价及勘查有一定的指示意义.分析国内外200多个矿床闪锌矿Cd、Fe含量数据,有8个矿床注明了闪锌矿形成的矿化阶段.其中4个矿床早阶段产生的闪锌矿比晚阶段形成的闪锌矿富Fe、贫Cd,4个矿床早阶段结晶的闪锌矿比晚阶段形成的闪锌矿既富Fe,又富Cd.反映矿床形成的地质构造和物理化学环境,矿液来源及演化史绝然不同.

| Abstract: | Sphalerite is the most common mineral in many deposits.The relationship studies between Cd,Fe contents and mineralization stages of sphalerite can infer the fluid evolution history and the history of environmental change during the mineral deposit formation,and have some implications in evaluation and exploration of deposits.Analizing more than 200 deposits worldwide,there have 8 deposits whose sphalerite mineralization stages have been marked out.In 4 deposits,sphalerite generated in the early deposit stage contains more Fe and less Cd than those of sphalerite generated in the late deposit stage;in other 4 deposits,sphalerite generated in the early deposit stage contains more Fe and more Cd than those of sphalerite generated in the late deposit stage.It suggests that geologic structures,physicochemical environments,fluid sources and evolution history of these deposits are totally different. |
