五十年代后期以来,研究微量元素地球化学相标志,用以说明沉积环境的工作日益受到重视,发表的文章越来越多。从已有的资料和我们自己的经验看,硼在研究盆地水介质含盐度的变化方面是一个较有效的标志。 本文以江汉盆地潜江凹陷白垩-第三系硼的地球化学研究成果为例,进一步探讨硼在研究沉积环境和评价生油岩中的作用。在探讨之前首先介绍一下样品的处理和分析方法。 Since the late 1950s, more and more articles have been published on the study of the geochemical phase trace of trace elements to illustrate the sedimentary environment. Based on the available information and our own experience, boron is a more effective indicator of the salinity of aqueous media in basin. This paper takes the geochemical study of boron in the Tertiary in Qianjiang Sag, Jianghan Basin as an example to further explore the role of boron in the study of sedimentary environment and in the evaluation of source rocks. Before discussing the first to introduce the sample processing and analysis methods.
