Some scientists think the Great Unconformity was caused by Snowball Earth’s glaciations. Recent work suggests these phenomena might not be related.
A Day in the Life Used to Be 17 Hours
The Moon was a lot closer to Earth 2.46 billion years ago, and the shorter distance contributed to shorter days.
What Can Zircons Tell Us About the Evolution of Plants?
The versatile mineral could contain evidence of the evolution of land plants and their effect on the sedimentary system.
Supervolcanoes Linger a While, Then Rush to Erupt
Geologists examined crystals in rock from four massive eruptions in the Chilean Andes.
Uncovering the Formation of the Western Nepal Embayment
Using thermokinematics, researchers have found that crustal accretion along the megathrust at mid-lower crustal depths shapes plateau growth and regional drainage development.
Searching for Earth’s Oldest Rocks in its Youngest Deposits
By sampling and analyzing zircons from glacial eskers dating from about 20,000 years ago, the extent of the oldest known rocks on Earth can be better mapped and constrained.
Sorting Minerals Differently Could Usher a New Era for Mineralogy
Grouping minerals by how they were formed yields insights into our planet’s evolution across billions of years.
Time-Step Filtering in Holocene Global Magnetic Field Models
Through a local fixed time-step filter, global Holocene magnetic field models remain mathematically tractable refining our insight into field variability and improving archeological dating.
A Puzzle Mat for Assembling Colombia’s Geologic History
A new database compiles all the available pieces of information about Colombia’s geochronology, offering scientists a consistent framework in which to view and study the data in a broader context.
