While zircons from this time period have not yet been studied, Halverson notes that previous studies of snowball Earth have tracked the presence of iron, neodymium, and osmium in the geologic record.

This ancient period of deep freeze, known as the Neoproterozoic Era, or “Snowball Earth,” lasted from about 1 billion to 543 million years ago. During that time, landmasses consolidated into a ...

700 million years ago, the Earth was almost entirely frozen, an episode called "Snowball Earth". Its titanic glaciers played a role in the evolution of complex life. A recent study reveals how these ...

According to the Snowball Earth hypothesis, Earth underwent at least two extreme global glaciations during the Cryogenian. Traces of these events can be seen across the globe in sedimentary rocks ...

Known as the Snowball Earth hypothesis, it suggests that runaway cold temperatures launched a series of deep freezes that enveloped the world in glaciers. Now, scientists say those prehistoric ...
