| 摘 要： | 显微红外测温技术是红外显微镜通过红外成像系统研究不透明和半透明矿物的流体包裹体的丰度和分布特征,并与冷热台相结合,进行流体包裹体显微测温分析的一种技术手段。本文以苏鲁超高压变质带东海榴辉岩中金红石矿床的流体包裹体研究为例,系统介绍了显微红外测温分析技术。结果表明,显微红外测温技术是研究半透明和不透明矿物中流体包裹体的一种十分有效的新手段,可见光和红外光两种光源下流体包裹体的测定不存在系统误差。利用红外显微镜进行半透明-不透明矿石矿物的流体包裹体测定时,循环技术法是测定冰点和均一温度的有效方法。江苏东海地区超高压变质带所经历的早期退变质阶段是金红石矿床的主要形成阶段。显微红外测温技术对研究矿床的成矿流体性质以及矿床成因等具有重要的意义。并将在金属矿床成矿流体的研究领域发挥重要的作用。

| Abstract: | Infrared micro-thermometric technique is an efficient mean to study fluid inclusions in opaque-translucentt minerals.In this paper,the detailed infrared micro-thermometric technology is introduced by taking the example from fluid inclusion study in rutile deposit in Donghai eclogite,Sulu ultrahigh-pressure metamorphic belt.The result indicates that the infrared micro-thermometric technology is a new powerful mean in studying nature of ore fluids and origin of ore deposit.No systematic error existed in fluid inclusion measurements between visible and infrared light.Cycling technique is an efficient method to measure ice-melting temperature and homogenization temperature of fluid inclusions under the infrared microscopy.Mineralization of futile in Donghai area took place main]y during the exhumation of the UHP metamorphic rocks.Infrared micro-thermometric technique will play an important role on the research of ore-forming fluid in metal deposits. |
