本文对赋存于中新统混杂沉积物中淡水序列(如粘土中的煤层夹矸,砂岩以及页岩)与连续的褐煤层相互交替的地层中的黄铁矿及黄铁矿形成过程中早期的成岩特征进行了研究。根据大量的矿物特征观察,黄铁矿形成的主要沉积环境为:伊利石-蒙脱石环境(I-M),方解石环境(Ct)和成煤环境。根?
In this paper, the early stage of the formation of pyrite and pyrite in the strata that alternates with the successive layers of lignite in the fresh water sequence of the Miocene mixed sediments (such as coal seam, sandstone and shale in clay) Diagenetic characteristics were studied. According to a large number of mineral characteristics observed, the main sedimentary environment formed by pyrite is: illite-montmorillonite environment (I-M), calcite environment (Ct) and coal-forming environment. root?
