石炭纪海平面波动的幅度并不为人所知，但估计是重要的约束旋回模型。在本文中，我们应用面积-体积的关系，第四纪冰盖估计冰川海平面变化的石炭纪组成部分。利用冈瓦纳冰面积最大时的最佳估计，我们得到均衡校正的冰川-海平面分量的数字为60 ±15米。这一数值更接近其他来源的旋回层波动海平面估计的下限。
The magnitude of Carboniferous sea-level fluctuations is not well known, but the estimates are important for constraining cyclothem models. In this paper we apply area-volume relations developed for Quaternary ice sheets to estimate the glacio-eustatic component of sea-level fluctuations in the Carboniferous. Utilizing the best estimate of Gondwanan ice area at the time of its greatest extent, we arrive at a figure of 60 ±15 m for the isostasy-corrected glacio-eustatic component. This value is nearer the lower limit of sea-level estimates for cyclothem fluctuations from other sources.
