运用稳定氧同位素 (δ18O)、Mg/Ca比值、碳酸盐胶结物和岩盐流体包裹体等方法 ,能够获得古环境温度或盐度参数 ,但这些方法本身存在各自缺陷 ,因而在实际应用中受到一定限制。文章首次检测到不同地区、不同层位和不同沉积环境中石英碎屑颗粒继承性裂纹和空隙胶结物捕获近地表同生流体包裹体均一温度和盐度。在成因上 ,它属于同沉积期或近地表捕获与古环境相关的次生 (裂纹中 )和原生 (硅质胶结物中 )盐水包裹体。因此 ,鉴别和测定这种类型的流体包裹体 ,为建立沉积环境古温度和古盐度的连续记录来了解古气候变迁而提供了一种可能的新途径。根据北海WestLewis和Shetland盆地、渤海渤中地区和南海莺歌海盆地钻井取心样品测定 ,证实了该方法的可靠性和实用性。
Paleo-ambient temperature or salinity parameters can be obtained using methods such as stable oxygen isotopes (δ18O), Mg / Ca ratios, carbonate cements, and rock salt fluid inclusions, but these methods have their own respective deficiencies and are, therefore, Certain restrictions. The article first detected the inheritance of quartz debris particles in different regions, different layers and sedimentary environments, and the spatial cementation fluid inclusions homogenization temperature and salinity of the mesoporosity fluid inclusions. Genesis, it belongs to the sedimentary or near-surface capture of paleo-environment-related secondary (in cracks) and native (siliceous cement) brine inclusions. Therefore, the identification and determination of this type of fluid inclusions provide a possible new avenue to establish a continuous record of palaeoclimate and paleosalinity in the sedimentary environment to understand paleoclimate changes. According to the drilling coring samples in WestLewis and Shetland basins in the North Sea, Bozhong area in the Bohai Sea and Yinggehai Basin in the South China Sea, the reliability and practicability of this method are verified.
