FOR 736: The Precambrian-Cambrian Biosphere (R)evolution: Insights from Chinese Microcontinents

包括埃迪卡拉纪(约630-543 Ma)和寒武纪(543-493 Ma)在内的这段时间段可以说代表了地球历史上最戏剧性的时期，其特征是全球构造、水和大气化学的同时发生深刻变化，以及可能“爆炸性”但无可争议的生物圈重大辐射事件。在这些事件之前，是地球历史上最严重的气候扰动之一，由几个世界范围的冰川记录下来，随后至少有一个同样极端的“温室效应”情景。这些变化可能最终是由大陆格局的重新安排，特别是罗迪尼亚超大陆的形成和解体所触发的。

The time interval including the Ediacaran (ca. 630-543 Ma) and the Cambrian (543-493 Ma) periods arguably represents the most dramatic time period in Earth's history, characterised by concurrent profound changes in global tectonics, in the chemistry of the hydro- and atmosphere and a possibly "explosive" but undisputed major radiation event of the biosphere. Preceding these events was one of the most severe climatic perturbations in Earth's history, documented by several world-wide glaciations, and followed by at least one equally extreme "greenhouse" scenario. These changes may have been ultimately triggered by rearrangement of the continental configuration, notably the formation and break-up of the supercontinent Rodinia.
