摘要早期地球过程通常通过研究岩石记录中的矿物学、元素和同位素特征来识别，包括前寒武纪条带状铁建造（BIF）。然而，沉积后的过程往往掩盖了主要的地球化学信号，使用BIF作为古海水和古生物圈的代理可能不精确。因此，需要其他方法来补充从岩石记录中获得的信息，以便充分了解古地球上独特的地球化学过程。在实验室中模拟这些条件是一种方法，但这种方法永远无法完全复制自然环境的复杂性。因此，寻找具有独特的地球化学和微生物特征的现代环境作为BIF沉积环境的类似物可以提供宝贵的信息。在这篇综述中，我们概述了已用作模拟BIF环境的现代含铁湖泊的化学、物理和生物参数。
Abstract Early Earth processes are typically identified through the study of mineralogical, elemental and isotopic features in the rock record, including Precambrian banded iron formations (BIF). However, post-depositional processes often obscure the primary geochemical signals, making the use of BIF as proxies for paleo-seawater and the paleo-biosphere potentially imprecise. Thus, alternative approaches are required to complement the information gained from the rock record in order to fully understand the distinctive biogeochemical processes on ancient Earth. Simulating these conditions in the laboratory is one approach, but this approach can never fully replicate the complexity of a natural environment. Therefore, finding modern environments with a unique set of geochemical and microbiological characteristics to use as analogues for BIF depositional environments can provide invaluable information. In this review, we provide an overview of the chemical, physical and biological parameters of modern, ferruginous lakes that have been used as analogue BIF environments.
