Question

The organic-rich Upper Ordovician sediments (Wufeng and Guanyinqiao Formations) on the Yangtze
platform are considered to be one of the main source rocks. Here we present geochemical proxies,
including redox indicator (S/C ratios and sulfur isotopes) and productivity indices (TOC, Mo and Ba
contents), from Nanbazi section in North Guizhou province, South China, in order to investigate the
mechanism of organic matter accumulation. The geochemical data suggest a stagnant and anoxic
environment predominated the Yangtze Sea during the Wufeng period, whereas ventilated and
oxygenated marine conditions pervaded the Yangtze Sea during the Guanyinqiao period. Variations in
the concentration of TOC, Mo and Ba indicate that higher organic carbon export in the Wufeng intervals
than those in the Guanyinqiao intervals. These variations in redox and productivity during the late
Ordovician were associated with different mechanisms and forcing processes. The abrupt change from
anoxic to oxygenated condition at the beginning of the Guanyinqiao was concomitant with the global
glacial period, likely resulted from the glacio-eustatic sea-level fall and subsequent circulation of cold,
dense oxygenated waters upon the shelf seabed. The productivity variations were related to the change

富含有机物上奥陶统沉积物（五峰和观音桥地层）上Yangtzeplatform被认为是主要的烃源岩之一。在这里，我们提出了地球化学代理，包括氧化还原指示剂（S / C比率和硫同位素）和生产力指数（TOC，Mo和Bacontents），从北贵州省，中国南方Nanbazi节，以探讨有机质积累themechanism。地球化学数据表明，停滞和anoxicenvironment为主的长江海在五峰期，而通风andoxygenated海洋条件弥漫长江海在观音桥时期。变化在矿井TOC，钼，钡的浓度表明在五峰，较高的有机碳的出口intervalsthan那些在观音桥区间。在lateOrdovician这些变化中的氧化还原和生产率都与不同的机制，并迫使流程。急剧变化fromanoxic以氧化条件在观音桥一开始是伴随着的globalglacial期内，在货架海底glacio，海平面的升降秋天寒冷，密集的含氧水和随后的循环可能会导致。生产率的变化均相关的变化本回答被提问者和网友采纳
