流体包裹体是研究矿物演化的重要手段之一.不同温度条件下生长的石盐矿物中,其流体包裹体中的个体形态、数量与大小不同,流体包裹体是反映成矿流体的成分、温度和压力的最直接证据.本文利用太赫兹时域光谱系统对石盐体系进行了检测,根据样品的吸收系数变化建立了石盐矿物在温度环境下的演化模型,总结出石盐矿物的成岩过程:即早成岩期、晚成岩期和近似变质阶段,采用XRD和包裹体显微镜测试为辅助手段进行分析,并通过理论模拟进一步验证了演化模型的正确性,实现了利用太赫兹技术对地质成岩成矿演化过程的评价.
Fluid inclusions are one of the most important means to study the evolution of minerals.The mineral inclusions in the fluid inclusions of rock salt minerals grown under different temperature have different morphologies, And stress the most direct evidence.In this paper, the use of terahertz time-domain spectroscopy system for the detection of rock salt, according to the sample absorption coefficient established a rock salt mineral evolution model in the temperature environment, summed up the rock salt mineral diagenetic process: That is, early diagenetic stage, late diagenetic stage and near metamorphic stage, using XRD and inclusion microscopy as ancillary tools to analyze and verify the correctness of the evolution model by theoretical simulation, to achieve the use of terahertz technology for geological diagenetic mineralization Evaluation of evolutionary process.
