Neoproterozoic. The later part of the Neoproterozoic records the break-up of the Rodinia supercontinent and the formation of the Iapetus Ocean. Passive margin sequences are preserved within the lowermost allochthon and parautochthon of the Caledonian thrust sheets. In southern Norway the sequence is known as Sparagmite.

Cambrian Period, earliest time division of the Paleozoic Era, extending from 541 million to 485.4 million years ago. The Cambrian Period is divided into four stratigraphic series: the Terreneuvian Series (541 million to 521 million years ago), Series 2 (521 million to 509 million years ago), Series 3 (509 million to 497 million years ago), and the Furongian Series (497 million to 485.4 million ...

Jun 18, 2020 · Earth’s hottest periods—the Hadean, the late Neoproterozoic, the Cretaceous Hot Greenhouse, the PETM—occurred before humans existed. Those ancient climates would have been like nothing our species has ever seen. Modern human civilization, with its permanent agriculture and settlements, has developed over just the past 10,000 years or so.

Around the top of Neoproterozoic glacial deposits there is commonly a sharp transition into a chemically precipitated sedimentary limestone or dolomite metres to tens of metres thick. These cap carbonates sometimes occur in sedimentary successions that have no other carbonate rocks, suggesting that their deposition is result of a profound aberration in ocean chemistry.

The Sturtian glaciation was a glaciation, or perhaps multiple glaciations, during the Cryogenian Period when the Earth experienced repeated large-scale glaciations. The duration of the Sturtian glaciation has been variously defined, with dates ranging from 717 to 643 Ma. Stern et al. place the period at 715 to 680 Ma.. According to Eyles and Young, "Glaciogenic rocks figure …
