一、引言在沉积岩的形成和变化过程中,特别是在成岩过程中,有机质在促进各种元素的迁移、富集和使它们从一种矿物转变为另一种矿物上,有着很大的作用。近年来,有机地球化学的研究,不仅在可燃性有机岩方面有很大的进展,而且在沉积非金属和金属矿床,特别是在稀有分散元素和放射性元素矿床的研究中,也得到了极大的重视和发展。在一般沉积岩中常或多或少的含有有机质,但目前还没有直接测定其总含量的简便完善的方法。由于碳是有机质的主要组成元素,因此普通采用岩石中的有机碳含量作为有机质总含量的标志。由于工作的需要,我们对测定有机碳的湿烧法进行了试验研究,并在测定方法上作了一些改进。现将该方法报导如下,请批评指正。
I. INTRODUCTION In the process of sedimentary rock formation and change, especially in the process of diagenesis, organic matter plays an important role in promoting the migration and enrichment of various elements and their transformation from one mineral to another . In recent years, the study of organic geochemistry has not only made great progress not only in flammable organic rocks, but also in the deposition of nonmetal and metal deposits, especially in the study of rare dispersed elements and radioactive element deposits The importance and development. In general sedimentary rocks often contain more or less organic matter, but there is no direct measurement of the total content of the simple and complete method. Since carbon is the major component of organic matter, the organic carbon content of rocks is commonly used as a marker of the total organic matter content. Due to the needs of the work, we conducted a pilot study on the wet combustion method for the determination of organic carbon, and made some improvements in the determination method. The method is reported as follows, please comment on criticism.
