在含煤地层中,黄铁矿是一种常见的、分布很普遍的矿物。但在过去的地质勘探和生产过程中,人们往往把它当作有害无益的矿物,因此很少进行研究。原生黄铁矿形成在成煤初期。这一时期,泥炭沼泽中堆积了大量的生物残体,其中有一部分的植物茎及生活在水体中的菌藻类生物遗体被黄铁矿化,使其免受后来成煤(岩)作用的破坏而保存下来,这样研究原生黄铁矿中的生物化石对成煤物质和成煤环境就具有一定的意义。
In coal-bearing formations, pyrite is a common, widely distributed mineral. However, in the past, geological exploration and production process, people often regard it as harmful minerals, so little research. Primary pyrite formed in the early coal formation. During this period, a large number of biological residues were accumulated in the peat swamps. Some of the plant stems and the living algae of living algae living in the water bodies were pyritized to protect them from later coal-forming (rock) destruction However, it is of great significance to study the biological fossils in native pyrite for coal-forming materials and coal-forming environment.
