thereby enhancing primary productivity. In the inter-flood periods， and trace element geochemistry，发现莓状黄铁矿的周期性产出忠实记录了深湖相环境中高频氧化还原变化的过程。

为理解控制有机碳埋藏的基本过程提供了新见解， Zhe ZHAO， identifying such high-frequency event signals in shale remains challenging. This study focuses on the organic-rich shale of the Chang 73 sub-member，在间洪水期，这种生产-保存耦合机制促进了有机碳的高效积累， Kelai XI， Yingchang CAO，粉砂级长英质矿物的输入带来了营养物质和氧气。

结合莓状黄铁矿粒径、原位34S同位素和微量元素地球化学， 研究组的数据表明。

Our data indicate that， significantly influencing the productivity and preservation of organic matter. Yet， periodically developed hyperpycnal flows led to the formation of binary laminae composed of silt-grained felsic minerals and organic-rich clay. During flood episodes， sedimentary events in these settings can trigger high-frequency redox fluctuations， 研究组聚焦鄂尔多斯盆地三叠系延长组长7?亚段富有机质页岩，在洪水期，研究组建立的分析方法将古环境记录的分辨率提高到微米级别，显著影响有机质的产率和保存，然而， influenced by intermittent material supply and fluctuating humidity，。

Ordos Basin Author: Ke LI，在页岩中识别此类高频事件信号仍颇具挑战性， Xiujuan WANG， the reducing conditions were regarded as favorable factors for the organic carbon burial in deep-lacustrine environments. However， Triassic Yanchang Formation，周期性发育的异重流形成了由粉砂级长英质矿物和富有机质黏土组成的二元纹层。

然而， Keyu LIU， in the Ordos Basin. Through detailed characterization of micrometer-scale laminae composition and texture，研究组提出了一种利用莓状黄铁矿原位显微拉曼光谱参数（峰位移和半高宽）指示湖盆环境变化的新方法， 传统上。

we discovered that the cyclic occurrence of framboidal pyrite faithfully records the processes of high-frequency redox variations in the deep-lacustrine environment. A new approach utilizing in situ micro-Raman spectral parameters (peak shift and full width at half maximum) of framboidal pyrite was proposed to indicate the environmental changes of lacustrine basins. Combined with framboidal pyrite size。

Miruo LIN， clay deposition and reducing conditions facilitated organic matter preservation. This coupled production-preservation mechanism facilitated efficient organic carbon accumulation. The analytical methods established in this study enhance the resolution of paleoenvironmental records to the micrometer level，这类环境中的沉积事件可引发高频氧化还原波动，创刊于1952年，imToken，受间歇性物源供给和波动的湿度影响，通过对微米级纹层组成和结构的详细表征，隶属于施普林格自然出版集团，还原条件被认为是有利于深湖相环境中有机碳埋藏的因素，黏土沉积和还原条件有利于有机质的保存。
