海绿石矿物一般是在正常盐度的浅海环境中生成,可作为良好的指相矿物。在无化石的地层中海绿石可用来测定同位素年龄、进行地层对比和解释地层间断。此外,海绿石也可作为储油层沉积环境的综合指标之一。 本文通过各种方法对我国某些地区砂岩类型的自生海绿石的矿物学特征作了综合系统的研究。试图通过从已知到未知、从现代到古代作对比,对松辽盆地的某些储油层段相环境的确定,提出必要的实际资料,进而来讨论它们的沉积环境。
The pyrochlore minerals are generally formed in shallower saltwater environments at normal salinity and can be used as good finger-phase minerals. In fossil-free formations, chlorite can be used to determine isotopic age, stratigraphic correlation and interpretation of stratigraphic discontinuities. In addition, glauconite can also be used as a comprehensive indicator of reservoir sedimentary environment. In this paper, a comprehensive and systematic study on the mineralogical characteristics of the spontaneous glauconites of sandstone in some areas of China is made through various methods. Trying to make some comparisons of the phase environment of some reservoirs in the Songliao Basin by making a comparison from known to unknown and from modern to ancient times, and put forward the necessary practical data to discuss their sedimentary environment.
