自生黄铁矿是在介质处于还原条件下形成的。它是一种能够反映沉积环境的重要指示矿物。研究现代海洋沉积物中自生黄铁矿的形成作用、分布规律和相关因素,对于探讨现代乃至古地质时期的某一海域的沉积环境具有重要意义。通过对我国北黄海沉积物中的重矿物分析,发现所含的自生黄铁矿主要富集在西部海域的成烟渔场一带,说明那里的沉积环境有着自己的特殊性。为此,本文试图从北黄海沉积物中自生黄
Authigenic pyrite is formed when the medium is under reducing conditions. It is an important indicator of minerals that reflect the sedimentary environment. Studying the formation, distribution and related factors of authigenic pyrite in modern marine sediments is of great significance for exploring the sedimentary environment of a certain sea area in modern and even paleogeological periods. Based on the analysis of heavy minerals in the sediments of North Yellow Sea in China, it is found that the authigenic pyrite contained in the sediments of the western sea area is mainly concentrated in the area where the sediments are located, indicating that the sedimentary environment has its own particularity. To this end, this article attempts to yellow from the North Yellow Sea sediments
