| 摘 要： | 缺氧沉积环境是一种能够提供多种类型矿化定位的特殊沉积环境。缺氧环境判识指标包括岩石、古生物和地球化学三方面。在缺氧环境的研究中,地球化学指标如矿物、微量元素、同位素和有机地球化学指标最为重要。因受地质历史中诸多因素的影响,地球化学指标具有一定的多解性和局限性,故只有多项参数综合应用才可更为准确地进行环境分析。

| Abstract: | Anoxic sedimentary environment is a special sedimentary environment where vari-
ous mineralizations take place. Indicators for diagnosing anoxic settings deal with three aspects
such as lithology, paleontology and geochemistry. The geochemical indicators, such as mineral,
trace element and isotopic geochemistry and organic geochemistry indices, are of the most impor-
tance in the study of anoxic environment. Due to the affects of various factors from geological his-
tory, the geochemical indices bear multi-interpretation and limitations, so comprehensive appli-
cation of multi-parameters(indices) can help to accurately analyse the environmen |
