沉积盆地内形成的自生矿物,如黄铁矿、海绿石、菱铁矿等是在特定环境下形成的。研究它们的形态、成分、结构及构造,对于了解成岩作用早期的环境及变化,具有指相意义。在现代沉积物中,自生黄铁矿是最常见的矿物之一。人们对它的研究也比较早,研究的中心问题,集中于成因上。已有细菌化石说、胶体成因说和无机成因说。近 The formation of authigenic minerals in sedimentary basins, such as pyrite, glauconite, siderite and the like, are formed under specific circumstances. Studying their morphology, composition, structure and structure has the meaning to understand the environment and changes in the early stage of diagenesis. In modern sediments, authigenic pyrite is one of the most common minerals. People study it earlier, the central issue of research focuses on the causes. Bacterial fossils have been said that the causes of colloids and inorganic genesis said. near
